Ambient Air Monitoring
Ambient air monitoring in Georgia provides information on measured concentrations of criteria and noncriteria pollutants at selected locations. Criteria pollutants are those for which a standard has been adopted by the U.S. Environmental Protection Agency. Non-criteria pollutants, while having no standard, provide useful information on the quality and content of ambient air.
The current Georgia Air Sampling Network (G.A.S.N.), is comprised of 83 monitors at 57 locations in 29 counties. Monitoring takes place year round with the exception of ozone, which is sampled from April through October.
The monitoring network is composed of State and Local Air Monitoring Stations (SLAMS), National Air Monitoring Stations (NAMS), Special Purpose Monitoring (SPM), and Photochemical Assessment Monitoring Stations (PAMS) and air toxic monitoring stations. During 1999, the network contained 14 NAMS, 47 SLAMS, and 36 SPM monitors. The 1998 PAMS and air toxic networks consisted of 4 and 9 sites respectively.
The number and location of the individual sites vary from year to year, depending on a variety of reasons that include: availability of long-term space allocation; citizen complaint; regulatory need; etc. Once the site is established, it is our intention to monitor for long-term trends.
In general, the basic monitoring objectives that govern the selection of sites are: 1) to determine the highest concentration expected to occur; 2) to determine representative concentrations in areas of high population density; 3) to determine the impact on ambient pollution levels of significant sources or source categories; 4) to determine the general background concentration levels; and 5) to determine the concentration of a number of compounds which may aid in the generation of ground level ozone.

PARTICULATE MATTER (PM-2.5)
Sources:
Particulate matter consists of the solid particles and liquid droplets found in the air. Individually, these particles and droplets are invisible to the naked eye. Collectively, however, they can appear as clouds or a fog-like haze.
Particulate matter less than 2.5 microns in diameter is referred to as "fine" particles. (In comparison, a human hair is about 70 microns in diameter.) Fine particles result from many different sources including industrial and residential combustion and vehicle exhaust so their composition varies widely. Fine particles can also be formed when combustion gases are chemically transformed into particles.
Particulate matter larger than 2.5 microns in diameter is referred to as coarse particles. Coarse particles have many sources, including wind-blown dust, vehicles traveling on unpaved roads, materials handling, and crushing and grinding operations.
Both coarse and fine particles are of health concern because they can penetrate into the sensitive regions of the respiratory tract. Fine particles are of greatest concern because they are linked to the most serious effects. They can cause persistent coughs, phlegm, wheezing, and physical discomfort.
Several recently published community health studies indicate that significant respiratory and cardiovascular-related problems are associated with exposure to particle levels well below the existing particulate matter standards. These negative effects include premature death, hospital admissions from respiratory causes, and increased respiratory symptoms. Long-term exposure to particulate matter may increase the rate of respiratory and cardiovascular illness and reduce life span.
Children, the elderly, and individuals with cardiovascular disease or lung diseases such as emphysema and asthma are especially vulnerable.
Fine particles can soil man-made materials, speed their deterioration, and impair visibility.
50.7 National primary and secondary ambient air quality standards for particulate matter. (a)The national primary and secondary ambient air quality standards for particulate matter are: (1) 15.0 micrograms per cubic meter mg/m 3 ) annual arithmetic mean concentration, and 65 mg/m 3 24-hour average concentration measured in the ambient air as PM2.5 (particles with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers) by either: i. A reference method based on appendix L of this part and designated in accordance with part 53 of this chapter; or ii. An equivalent method designated in accordance with part 53 of this chapter. (b) The annual primary and secondary PM2.5 standards are met when the annual arithmetic mean concentration, as determined in accordance with appendix N of this part, is less than or equal to 15.0 micrograms per cubic meter.
(b) The 24-hour primary and secondary PM2.5 standards are met when the 98th percentile 24-hour concentration, as determined in accordance with appendix N of this part, is less than or equal to 65 micrograms per cubic meter.

PARTICULATE MATTER (PM-10)
Sources: Particulate matter (PM) is solid matter or liquid droplets from smoke, dust, fly ash, or condensing vapors that can be suspended in the air for long periods of time. It represents a broad class of chemically diverse particles that range in size from molecular clusters of 0.005 micrometers (m) to coarse particles of 50-100 m in diameter (100 m is about the thickness of an average human hair). PM results from all types of combustion. The carbon-based particles that result from incomplete burning of diesel fuel in buses, trucks and cars are of particular concern. Another important combustion source is the burning of wood in stoves and fireplaces in residential settings. Also of concern are the sulfate and nitrate particles that are formed as a byproduct of SO2 and NO2 emissions, primarily from fossil fuel-burning power plants and vehicular exhausts.
The U.S. national ambient air quality standard was originally based on particles up to 25-45 m in size, termed "total suspended particles" (TSP). In 1987, EPA replaced TSP with an indicator that includes only those particles smaller than 10 m, termed PM-10. These smaller particles cause most of the adverse health effects because of their ability to penetrate deeply into the lungs. Health effects. The observed human health effects of PM include breathing and respiratory symptoms, aggravation of existing respiratory and cardiovascular disease, alterations in the body's defense system against inhaled materials and organisms, and damage to lung tissue. Groups that appear to be most sensitive to the effects of PM include individuals with chronic lung or cardiovascular disease, individuals with influenza, asthmatics, elderly people, and children. Health Effects: Marked increases in daily mortality have been statistically associated with very high 24hour concentrations of PM-10, with some increased risk of mortality at lower concentrations. Small increases in mortality appear to exist at even lower levels. Risks to sensitive individuals increase with consecutive, multi-day exposures to elevated PM concentrations. The research also indicates that aggravation of bronchitis occurs with elevated 24-hour PM-10 levels, and small decreases in lung function take place when children are exposed to lower 24-hour peak PM-10 levels. Lung function impairment persists for 2-3 weeks following exposure to PM.
National Primary and Secondary Ambient Air Quality Standards for Particulate Matter.
(a) The annual primary and secondary PM-10 standards are met when the annual arithmetic mean concentration, as determined in accordance with appendix N of this part, is less than or equal to 50 micrograms per cubic meter. (b) The 24-hour primary and secondary PM-10 standards are met when the 99th percentile 24hour concentration, is less than or equal to 150 micrograms per cubic meter. [62 FR 38711, July 18, 1997]

SULFUR DIOXIDE
Sources: Sulfur dioxide (SO2) is a colorless reactive gas that is ordorless at low concentrations, but pungent at very high concentrations. It is emitted primarily when fossil fuels and ores that contain sulfur are burned or processed. Major sources of SO2 are fossil fuel-burning power plants and industrial boilers.
Health Effects: Exposure to SO2 can cause impairment of respiratory function, aggravation of existing respiratory disease (especially bronchitis), and a decrease in the ability of the lungs to clear foreign particles. It can also lead to increased mortality, especially if elevated levels of particulate matter (PM) are also present. Groups that appear most sensitive to the effects of SO2 include asthmatics and other individuals with hyperactive airways, and individuals with chronic obstructive lung or cardiovascular disease. Elderly people and children are also likely to be sensitive to SO2.
Effects of short-term peak exposures have been evaluated in controlled human exposure studies. These studies show that SO2 generally increases airway resistance in the lungs, and can cause significant constriction of air passages in sensitive asthmatics. These impacts have been observed in subjects engaged in moderate to heavy exercise while exposed to relatively high peak concentrations. These changes in lung function are accompanied by perceptible symptoms such as wheezing, shortness of breath, and coughing in these sensitive groups.
The presence of PM appears to aggravate the impact of SO2 pollution. Several studies of chronic effects have found that people living in areas with high PM and SO2 levels have a higher incidence of respiratory illnesses and symptoms than people living in areas without such a synergistic combination of pollutants.
National Primary Ambient Air Quality Standards for Sulfur Oxides (Sulfur Dioxide).
(a) The level of the annual standard is 0.030 parts per million (ppm), not to be exceeded in a calendar year. The annual arithmetic mean shall be rounded to three decimal places (fractional parts equal to or greater than 0.0005 ppm shall be rounded up).
(b) The level of the 24-hour standard is 0.14 parts per million (ppm), not to be exceeded more than once per calendar year. The 24-hour averages shall be determined from successive nonoverlapping 24-hour blocks starting at midnight each calendar day and shall be rounded to two decimal places (fractional parts equal to or greater than 0.005 ppm shall be rounded up).
(c) Sulfur oxides shall be measured in the ambient air as sulfur dioxide by the reference method described in appendix A to this part or by an equivalent method designated in accordance with part 53 of this chapter.
(d) To demonstrate attainment, the annual arithmetic mean and the second-highest 24-hour averages must be based upon hourly data that are at least 75 percent complete in each calendar quarter. A 24-hour block average shall be considered valid if at least 75 percent of the hourly averages for the 24hour period are available. In the event that only 18, 19, 20, 21, 22, or 23 hourly averages are available, the 24-hour block average shall be computed as the sum of the available hourly averages using 18, 19, etc. as the divisor. If fewer than 18 hourly averages are available, but the 24-hour average would exceed the level of the standard when zeros are substituted for the missing values, subject to the rounding rule of paragraph (b) of this section, then this shall be considered a valid 24-hour average. In this case, the 24hour block average shall be computed as the sum of the available hourly averages divided by 24. [61 FR 25579, May 22, 1996]

OZONE
Sources: Ozone (O3), a colorless gas, is the major constituent of smog. It is produced by the chemical reaction of nitrogen dioxide with reactive organic substances such as hydrocarbons in automobile exhaust or vapors from cleaning solvents - in the presence of sunlight. This type of pollution first gained attention in the 1940's as Los Angeles "smog." Since then, photochemical smog has been observed frequently in many cities as well. (Note: In the upper atmosphere, naturally occurring ozone is beneficial in protecting us from the harmful solar rays.)
Health Effects: Ozone and other photochemical oxidants such as peroxyacyl nitrates and aldehydes are associated with health effects in humans. Peroxyacyl nitrates and aldehydes cause the irritation that is characteristic of photochemical pollution. Ozone has a greater impact on the respiratory system, where it irritates the mucous membranes of the nose, throat and airways; ninety percent of the ozone inhaled into the lungs is never exhaled. Symptoms associated with exposure include cough, chest pain, and throat irritation. Ozone can also increase susceptibility to respiratory infections. In addition, ozone impairs normal functioning of the lungs and reduces the ability to perform physical exercise. Recent studies also suggest that even at lower ozone concentrations some healthy individuals engaged in moderate exercise for 6 to 8 hours may experience symptoms. All of these effects are more severe in individuals with sensitive respiratory systems, and studies show that moderate levels may impair the ability of individuals with asthma or respiratory disease to engage in normal daily activities.
The potential chronic effects of repeated exposure to ozone are of even greater concern. Laboratory studies show that people exposed over a 6 to 8 hour period to relatively low ozone levels develop lung inflammation. Animal studies suggest that if exposures are repeated over a long period (e.g. months, years, lifetime), inflammation of this type may lead to permanent scarring of lung tissue, loss of lung function, and reduced lung elasticity.
National 1-hour primary and secondary ambient air quality standards for ozone: (a) The level of the national 1-hour primary and secondary ambient air quality standards for ozone measured by a reference method based on appendix D to this part and designated in accordance with part 53 of this chapter is 0.12 parts per million (235 ug/m3). The standard is attained when the expected number of days per calendar year with maximum hourly average concentrations above 0.12 parts per million (235 ug/m3) is equal to or less than 1, as determined by appendix H to this part. (b) The 1-hour standards set forth in this section will no longer apply to an area, once EPA determines that the area has air quality meeting the 1-hour standard. Area designations are codified in 40 CFR part 81. (62 FR 38894, July 18, 1997)

CARBON MONOXIDE
Sources: Carbon Monoxide (CO) is an odorless, colorless gas that is a by-product of the incomplete burning of fuels. Industrial processes contribute to CO pollution levels, but the principal source of CO pollution in most large urban areas is the automobile. Cigarettes and other sources of incomplete burning in the indoor environment also produce CO. CO is inhaled and enters the blood stream; there it binds chemically to hemoglobin, the substance that carries oxygen to the cells, thereby reducing the amount of oxygen delivered to all tissues of the body. The percentage of hemoglobin inactivated by CO depends on the amount of air breathed, the concentration of CO in air, and length of exposure; this is indexed by the percentage of carboxyhemoglobin found in the blood. Health Effects: CO weakens the contractions of the heart, thus reducing the amount of blood pumped to various parts of the body and, therefore, the oxygen available to the muscles and various organs. In a healthy person, this effect significantly reduces the ability to perform physical exercises. In persons with chronic heart diseases, these effects can threaten the overall quality of life, since their systems are unable to compensate for the decrease in oxygen. CO pollution is also likely to cause such individuals to experience angina during exercise. Adverse effects have also been observed in individuals with heart conditions who are exposed to CO pollution in heavy freeway traffic for 1 to 2 hours or more. In addition, fetuses, young infants, pregnant women, elderly people, and individuals with anemia or emphysema are likely to be more susceptible to the effects of CO. For these individuals, the effects are more pronounced when exposure takes place at high altitude locations, where oxygen concentration is lower. CO can also affect mental function, visual activity, and alertness of healthy individuals, even at relatively low concentrations.
National primary ambient air quality standards for carbon monoxide: (a) The national primary ambient air quality standards for carbon monoxide are: (1) 9 parts per million (10 milligrams per cubic meter) for an 8-hour average concentration not to be exceeded more than once per year and (2) 35 parts per million (40 milligrams per cubic meter) for a 1-hour average concentration not to be exceeded more than once a year.

NITROGEN DIOXIDE
Sources: Nitrogen dioxide (NO2) is a light brown gas that can become an important component of urban haze. Nitrogen oxides usually enter the air as the result of high-temperature combustion processes, such as those occurring in automobiles and power plants. NO2 plays an important role in the atmospheric reactions that generate ozone. Home heaters and gas stoves also produce substantial amounts of NO2.
Health Effects: Healthy individuals experience respiratory problems when exposed to high levels of NO2 for short durations (less than three hours). Asthmatics are especially sensitive, and changes in airway responsiveness have been observed in some studies of exercising asthmatics exposed to relatively low levels of NO2. Studies also indicate a relationship between indoor NO2 exposures and increased respiratory illness rates in young children, but definitive results are still lacking. Many animal studies suggest that NO2 impairs respiratory defense mechanisms and increases susceptibility to infection.
Several studies also show that chronic exposure to relatively low NO2 pollution levels may cause structural changes in the lungs of animals. These studies suggest that chronic exposure to NO2 could lead to adverse health effects in humans, but specific levels and durations likely to cause such effects have not yet been determined.
National Primary and Secondary Ambient Air Quality Standards for Nitrogen Dioxide
(a) The level of the national primary ambient air quality standard for nitrogen dioxide is 0.053 parts per million (100 micrograms per cubic meter), annual arithmetic mean concentration. (b) The level of national secondary ambient air quality standard for nitrogen dioxide is 0.053 parts per million (100 micrograms per cubic meter), annual arithmetic mean concentration. (c) The levels of the standards shall be measured by:
(1) A reference method based on appendix F and designated in accordance with part 53 of this chapter, or (2) An equivalent method designated in accordance with part 53 of this chapter. (d) The standards are attained when the annual arithmetic mean concentration in a calendar year is less than or equal to 0.053 ppm, rounded to three decimal places (fractional parts equal to or greater than 0.0005 ppm must be rounded up). To demonstrate attainment, an annual mean must be based upon hourly data that are at least 75 percent complete or upon data derived from manual methods that are at least 75 percent complete for the scheduled sampling days in each calendar quarter.

LEAD
Nature and Sources of the Pollutant: In the past, automotive sources were the major contributor of Pb emissions to the atmosphere. As a result of EPA's regulatory efforts to reduce the content of Pb in gasoline, the contribution from the transportation sector has declined over the past decade. Today, metals processing is the major source of Pb emissions to the atmosphere. The highest air concentrations of Pb are found in the vicinity of nonferrous and ferrous smelters, and battery manufacturers. Health and Environmental Effects: Exposure to Pb occurs mainly through inhalation of air and ingestion of Pb in food, water, soil, or dust. It accumulates in the blood, bones, and soft tissues. Lead can adversely affect the kidneys, liver, nervous system, and other organs. Excessive exposure to Pb may cause neurological impairments, such as seizures, mental retardation, and behavioral disorders. Even at low doses, Pb exposure is associated with damage to the nervous systems of fetuses and young children, resulting in learning deficits and lowered IQ. Recent studies also show that Pb may be a factor in high blood pressure and subsequent heart disease. Lead can also be deposited on the leaves of plants, presenting a hazard to grazing animals. National primary and secondary ambient air quality standards for lead: National primary and secondary ambient air quality standards for lead and its compounds, measured as elemental lead, are: 1.5 micrograms per cubic meter, maximum arithmetic mean averaged over a calendar quarter.

PAMS The Environmental Protection Agency (EPA) has revised the ambient air quality surveillance regulations in Title 40 Part 58 of the Code of Federal Regulations (40 CFR Part 58) to include provisions for enhanced monitoring of ozone, oxides of nitrogen, volatile organic compounds (VOCs), selected carbonyl compounds, and monitoring of meteorological parameters. The revisions require States to establish Photochemical Assessment Monitoring Stations (PAMS) as part of their existing State Implementation Plan (SIP) monitoring networks in ozone non-attainment areas classified as serious, severe, or extreme. The principal reasons for requiring the collection of additional ambient air pollutant and meteorological data are the lack of successful attainment of the National Ambient Air Quality Standard (NAAQS) for ozone, and the need to obtain a more comprehensive air quality data base for ozone and its precursors. Analysis of the data will help the EPD understand the underlying causes of ozone pollution, devise effective controls, and measure improvement.

1998 Air Toxics Monitoring Results Toxic air pollutants are also referred to as air toxics or hazardous air pollutants (HAPs). They are generally defined as those pollutants that are known or suspected to cause serious health problems. "Routine" toxic air pollutants are emitted by a variety of industrial sources and motor vehicles. In addition to routine releases, sudden accidental air releases of toxics potentially threaten many Americans. In response to public concern over the quality of Georgia's air, the Environmental Protection Division began an ambitious project in 1997 to establish, over the course of several years, nineteen sites to monitor non-criteria metals, semi volatiles, volatiles and carbonyl compounds. In 1998 there were a total of nine sites in nine counties monitoring for noncriteria pollutants. The following tables are the results of that monitoring

Ambient Air Monitoring
Ambient air monitoring in Georgia provides information on measured concentrations of criteria and noncriteria pollutants at selected locations. Criteria pollutants are those for which a standard has been adopted by the U.S. Environmental Protection Agency. Non-criteria pollutants, while having no standard, provide useful information on the quality and content of ambient air.
The current Georgia Air Sampling Network (G.A.S.N.), is comprised of 83 monitors at 57 locations in 29 counties. Monitoring takes place year round with the exception of ozone, which is sampled from April through October.
The monitoring network is composed of State and Local Air Monitoring Stations (SLAMS), National Air Monitoring Stations (NAMS), Special Purpose Monitoring (SPM), and Photochemical Assessment Monitoring Stations (PAMS) and air toxic monitoring stations. During 1999, the network contained 14 NAMS, 47 SLAMS, and 36 SPM monitors. The 1998 PAMS and air toxic networks consisted of 4 and 9 sites respectively.
The number and location of the individual sites vary from year to year, depending on a variety of reasons that include: availability of long-term space allocation; citizen complaint; regulatory need; etc. Once the site is established, it is our intention to monitor for long-term trends.
In general, the basic monitoring objectives that govern the selection of sites are: 1) to determine the highest concentration expected to occur; 2) to determine representative concentrations in areas of high population density; 3) to determine the impact on ambient pollution levels of significant sources or source categories; 4) to determine the general background concentration levels; and 5) to determine the concentration of a number of compounds which may aid in the generation of ground level ozone.

PARTICULATE MATTER (PM-2.5)
Sources:
Particulate matter consists of the solid particles and liquid droplets found in the air. Individually, these particles and droplets are invisible to the naked eye. Collectively, however, they can appear as clouds or a fog-like haze.
Particulate matter less than 2.5 microns in diameter is referred to as "fine" particles. (In comparison, a human hair is about 70 microns in diameter.) Fine particles result from many different sources including industrial and residential combustion and vehicle exhaust so their composition varies widely. Fine particles can also be formed when combustion gases are chemically transformed into particles.
Particulate matter larger than 2.5 microns in diameter is referred to as coarse particles. Coarse particles have many sources, including wind-blown dust, vehicles traveling on unpaved roads, materials handling, and crushing and grinding operations.
Both coarse and fine particles are of health concern because they can penetrate into the sensitive regions of the respiratory tract. Fine particles are of greatest concern because they are linked to the most serious effects. They can cause persistent coughs, phlegm, wheezing, and physical discomfort.
Several recently published community health studies indicate that significant respiratory and cardiovascular-related problems are associated with exposure to particle levels well below the existing particulate matter standards. These negative effects include premature death, hospital admissions from respiratory causes, and increased respiratory symptoms. Long-term exposure to particulate matter may increase the rate of respiratory and cardiovascular illness and reduce life span.
Children, the elderly, and individuals with cardiovascular disease or lung diseases such as emphysema and asthma are especially vulnerable.
Fine particles can soil man-made materials, speed their deterioration, and impair visibility.
50.7 National primary and secondary ambient air quality standards for particulate matter. (a)The national primary and secondary ambient air quality standards for particulate matter are: (1) 15.0 micrograms per cubic meter mg/m 3 ) annual arithmetic mean concentration, and 65 mg/m 3 24-hour average concentration measured in the ambient air as PM2.5 (particles with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers) by either: i. A reference method based on appendix L of this part and designated in accordance with part 53 of this chapter; or ii. An equivalent method designated in accordance with part 53 of this chapter. (b) The annual primary and secondary PM2.5 standards are met when the annual arithmetic mean concentration, as determined in accordance with appendix N of this part, is less than or equal to 15.0 micrograms per cubic meter.
(b) The 24-hour primary and secondary PM2.5 standards are met when the 98th percentile 24-hour concentration, as determined in accordance with appendix N of this part, is less than or equal to 65 micrograms per cubic meter.

PARTICULATE MATTER (PM-10)
Sources: Particulate matter (PM) is solid matter or liquid droplets from smoke, dust, fly ash, or condensing vapors that can be suspended in the air for long periods of time. It represents a broad class of chemically diverse particles that range in size from molecular clusters of 0.005 micrometers (m) to coarse particles of 50-100 m in diameter (100 m is about the thickness of an average human hair). PM results from all types of combustion. The carbon-based particles that result from incomplete burning of diesel fuel in buses, trucks and cars are of particular concern. Another important combustion source is the burning of wood in stoves and fireplaces in residential settings. Also of concern are the sulfate and nitrate particles that are formed as a byproduct of SO2 and NO2 emissions, primarily from fossil fuel-burning power plants and vehicular exhausts.
The U.S. national ambient air quality standard was originally based on particles up to 25-45 m in size, termed "total suspended particles" (TSP). In 1987, EPA replaced TSP with an indicator that includes only those particles smaller than 10 m, termed PM-10. These smaller particles cause most of the adverse health effects because of their ability to penetrate deeply into the lungs. Health effects. The observed human health effects of PM include breathing and respiratory symptoms, aggravation of existing respiratory and cardiovascular disease, alterations in the body's defense system against inhaled materials and organisms, and damage to lung tissue. Groups that appear to be most sensitive to the effects of PM include individuals with chronic lung or cardiovascular disease, individuals with influenza, asthmatics, elderly people, and children. Health Effects: Marked increases in daily mortality have been statistically associated with very high 24hour concentrations of PM-10, with some increased risk of mortality at lower concentrations. Small increases in mortality appear to exist at even lower levels. Risks to sensitive individuals increase with consecutive, multi-day exposures to elevated PM concentrations. The research also indicates that aggravation of bronchitis occurs with elevated 24-hour PM-10 levels, and small decreases in lung function take place when children are exposed to lower 24-hour peak PM-10 levels. Lung function impairment persists for 2-3 weeks following exposure to PM.
National Primary and Secondary Ambient Air Quality Standards for Particulate Matter.
(a) The annual primary and secondary PM-10 standards are met when the annual arithmetic mean concentration, as determined in accordance with appendix N of this part, is less than or equal to 50 micrograms per cubic meter. (b) The 24-hour primary and secondary PM-10 standards are met when the 99th percentile 24hour concentration, is less than or equal to 150 micrograms per cubic meter. [62 FR 38711, July 18, 1997]

SULFUR DIOXIDE
Sources: Sulfur dioxide (SO2) is a colorless reactive gas that is ordorless at low concentrations, but pungent at very high concentrations. It is emitted primarily when fossil fuels and ores that contain sulfur are burned or processed. Major sources of SO2 are fossil fuel-burning power plants and industrial boilers.
Health Effects: Exposure to SO2 can cause impairment of respiratory function, aggravation of existing respiratory disease (especially bronchitis), and a decrease in the ability of the lungs to clear foreign particles. It can also lead to increased mortality, especially if elevated levels of particulate matter (PM) are also present. Groups that appear most sensitive to the effects of SO2 include asthmatics and other individuals with hyperactive airways, and individuals with chronic obstructive lung or cardiovascular disease. Elderly people and children are also likely to be sensitive to SO2.
Effects of short-term peak exposures have been evaluated in controlled human exposure studies. These studies show that SO2 generally increases airway resistance in the lungs, and can cause significant constriction of air passages in sensitive asthmatics. These impacts have been observed in subjects engaged in moderate to heavy exercise while exposed to relatively high peak concentrations. These changes in lung function are accompanied by perceptible symptoms such as wheezing, shortness of breath, and coughing in these sensitive groups.
The presence of PM appears to aggravate the impact of SO2 pollution. Several studies of chronic effects have found that people living in areas with high PM and SO2 levels have a higher incidence of respiratory illnesses and symptoms than people living in areas without such a synergistic combination of pollutants.
National Primary Ambient Air Quality Standards for Sulfur Oxides (Sulfur Dioxide).
(a) The level of the annual standard is 0.030 parts per million (ppm), not to be exceeded in a calendar year. The annual arithmetic mean shall be rounded to three decimal places (fractional parts equal to or greater than 0.0005 ppm shall be rounded up).
(b) The level of the 24-hour standard is 0.14 parts per million (ppm), not to be exceeded more than once per calendar year. The 24-hour averages shall be determined from successive nonoverlapping 24-hour blocks starting at midnight each calendar day and shall be rounded to two decimal places (fractional parts equal to or greater than 0.005 ppm shall be rounded up).
(c) Sulfur oxides shall be measured in the ambient air as sulfur dioxide by the reference method described in appendix A to this part or by an equivalent method designated in accordance with part 53 of this chapter.
(d) To demonstrate attainment, the annual arithmetic mean and the second-highest 24-hour averages must be based upon hourly data that are at least 75 percent complete in each calendar quarter. A 24-hour block average shall be considered valid if at least 75 percent of the hourly averages for the 24hour period are available. In the event that only 18, 19, 20, 21, 22, or 23 hourly averages are available, the 24-hour block average shall be computed as the sum of the available hourly averages using 18, 19, etc. as the divisor. If fewer than 18 hourly averages are available, but the 24-hour average would exceed the level of the standard when zeros are substituted for the missing values, subject to the rounding rule of paragraph (b) of this section, then this shall be considered a valid 24-hour average. In this case, the 24hour block average shall be computed as the sum of the available hourly averages divided by 24. [61 FR 25579, May 22, 1996]

OZONE
Sources: Ozone (O3), a colorless gas, is the major constituent of smog. It is produced by the chemical reaction of nitrogen dioxide with reactive organic substances such as hydrocarbons in automobile exhaust or vapors from cleaning solvents - in the presence of sunlight. This type of pollution first gained attention in the 1940's as Los Angeles "smog." Since then, photochemical smog has been observed frequently in many cities as well. (Note: In the upper atmosphere, naturally occurring ozone is beneficial in protecting us from the harmful solar rays.)
Health Effects: Ozone and other photochemical oxidants such as peroxyacyl nitrates and aldehydes are associated with health effects in humans. Peroxyacyl nitrates and aldehydes cause the irritation that is characteristic of photochemical pollution. Ozone has a greater impact on the respiratory system, where it irritates the mucous membranes of the nose, throat and airways; ninety percent of the ozone inhaled into the lungs is never exhaled. Symptoms associated with exposure include cough, chest pain, and throat irritation. Ozone can also increase susceptibility to respiratory infections. In addition, ozone impairs normal functioning of the lungs and reduces the ability to perform physical exercise. Recent studies also suggest that even at lower ozone concentrations some healthy individuals engaged in moderate exercise for 6 to 8 hours may experience symptoms. All of these effects are more severe in individuals with sensitive respiratory systems, and studies show that moderate levels may impair the ability of individuals with asthma or respiratory disease to engage in normal daily activities.
The potential chronic effects of repeated exposure to ozone are of even greater concern. Laboratory studies show that people exposed over a 6 to 8 hour period to relatively low ozone levels develop lung inflammation. Animal studies suggest that if exposures are repeated over a long period (e.g. months, years, lifetime), inflammation of this type may lead to permanent scarring of lung tissue, loss of lung function, and reduced lung elasticity.
National 1-hour primary and secondary ambient air quality standards for ozone: (a) The level of the national 1-hour primary and secondary ambient air quality standards for ozone measured by a reference method based on appendix D to this part and designated in accordance with part 53 of this chapter is 0.12 parts per million (235 ug/m3). The standard is attained when the expected number of days per calendar year with maximum hourly average concentrations above 0.12 parts per million (235 ug/m3) is equal to or less than 1, as determined by appendix H to this part. (b) The 1-hour standards set forth in this section will no longer apply to an area, once EPA determines that the area has air quality meeting the 1-hour standard. Area designations are codified in 40 CFR part 81. (62 FR 38894, July 18, 1997)
National 8-hour primary and secondary ambient air quality standards for ozone: (a) The level of the national 8-hour primary and secondary ambient air quality standards for ozone measured by a reference method based on appendix D to this part and designated in accordance with part 53 of this chapter is 0.12 parts per million (235 ug/m3). The standard is attained when the expected number of days per calendar year with maximum hourly average concentrations above 0.08 parts per million (ppm), daily maximum 8- hour average (b) The 8-hour primary and secondary ozone ambient air quality standards are met at an ambient air quality monitoring site when the average of the annual fourth-highest daily maximum 8-hour average ozone concentration is less than or equal to 0.08 ppm, as determined in accordance with appendix I to this part.

CARBON MONOXIDE
Sources: Carbon Monoxide (CO) is an odorless, colorless gas that is a by-product of the incomplete burning of fuels. Industrial processes contribute to CO pollution levels, but the principal source of CO pollution in most large urban areas is the automobile. Cigarettes and other sources of incomplete burning in the indoor environment also produce CO. CO is inhaled and enters the blood stream; there it binds chemically to hemoglobin, the substance that carries oxygen to the cells, thereby reducing the amount of oxygen delivered to all tissues of the body. The percentage of hemoglobin inactivated by CO depends on the amount of air breathed, the concentration of CO in air, and length of exposure; this is indexed by the percentage of carboxyhemoglobin found in the blood. Health Effects: CO weakens the contractions of the heart, thus reducing the amount of blood pumped to various parts of the body and, therefore, the oxygen available to the muscles and various organs. In a healthy person, this effect significantly reduces the ability to perform physical exercises. In persons with chronic heart diseases, these effects can threaten the overall quality of life, since their systems are unable to compensate for the decrease in oxygen. CO pollution is also likely to cause such individuals to experience angina during exercise. Adverse effects have also been observed in individuals with heart conditions who are exposed to CO pollution in heavy freeway traffic for 1 to 2 hours or more. In addition, fetuses, young infants, pregnant women, elderly people, and individuals with anemia or emphysema are likely to be more susceptible to the effects of CO. For these individuals, the effects are more pronounced when exposure takes place at high altitude locations, where oxygen concentration is lower. CO can also affect mental function, visual activity, and alertness of healthy individuals, even at relatively low concentrations.
National primary ambient air quality standards for carbon monoxide: (a) The national primary ambient air quality standards for carbon monoxide are: (1) 9 parts per million (10 milligrams per cubic meter) for an 8-hour average concentration not to be exceeded more than once per year and (2) 35 parts per million (40 milligrams per cubic meter) for a 1-hour average concentration not to be exceeded more than once a year.

NITROGEN DIOXIDE
Sources: Nitrogen dioxide (NO2) is a light brown gas that can become an important component of urban haze. Nitrogen oxides usually enter the air as the result of high-temperature combustion processes, such as those occurring in automobiles and power plants. NO2 plays an important role in the atmospheric reactions that generate ozone. Home heaters and gas stoves also produce substantial amounts of NO2.
Health Effects: Healthy individuals experience respiratory problems when exposed to high levels of NO2 for short durations (less than three hours). Asthmatics are especially sensitive, and changes in airway responsiveness have been observed in some studies of exercising asthmatics exposed to relatively low levels of NO2. Studies also indicate a relationship between indoor NO2 exposures and increased respiratory illness rates in young children, but definitive results are still lacking. Many animal studies suggest that NO2 impairs respiratory defense mechanisms and increases susceptibility to infection.
Several studies also show that chronic exposure to relatively low NO2 pollution levels may cause structural changes in the lungs of animals. These studies suggest that chronic exposure to NO2 could lead to adverse health effects in humans, but specific levels and durations likely to cause such effects have not yet been determined.
National Primary and Secondary Ambient Air Quality Standards for Nitrogen Dioxide
(a) The level of the national primary ambient air quality standard for nitrogen dioxide is 0.053 parts per million (100 micrograms per cubic meter), annual arithmetic mean concentration. (b) The level of national secondary ambient air quality standard for nitrogen dioxide is 0.053 parts per million (100 micrograms per cubic meter), annual arithmetic mean concentration. (c) The levels of the standards shall be measured by:
(1) A reference method based on appendix F and designated in accordance with part 53 of this chapter, or (2) An equivalent method designated in accordance with part 53 of this chapter. (d) The standards are attained when the annual arithmetic mean concentration in a calendar year is less than or equal to 0.053 ppm, rounded to three decimal places (fractional parts equal to or greater than 0.0005 ppm must be rounded up). To demonstrate attainment, an annual mean must be based upon hourly data that are at least 75 percent complete or upon data derived from manual methods that are at least 75 percent complete for the scheduled sampling days in each calendar quarter.

LEAD
Nature and Sources of the Pollutant: In the past, automotive sources were the major contributor of Pb emissions to the atmosphere. As a result of EPA's regulatory efforts to reduce the content of Pb in gasoline, the contribution from the transportation sector has declined over the past decade. Today, metals processing is the major source of Pb emissions to the atmosphere. The highest air concentrations of Pb are found in the vicinity of nonferrous and ferrous smelters, and battery manufacturers. Health and Environmental Effects: Exposure to Pb occurs mainly through inhalation of air and ingestion of Pb in food, water, soil, or dust. It accumulates in the blood, bones, and soft tissues. Lead can adversely affect the kidneys, liver, nervous system, and other organs. Excessive exposure to Pb may cause neurological impairments, such as seizures, mental retardation, and behavioral disorders. Even at low doses, Pb exposure is associated with damage to the nervous systems of fetuses and young children, resulting in learning deficits and lowered IQ. Recent studies also show that Pb may be a factor in high blood pressure and subsequent heart disease. Lead can also be deposited on the leaves of plants, presenting a hazard to grazing animals. National primary and secondary ambient air quality standards for lead: National primary and secondary ambient air quality standards for lead and its compounds, measured as elemental lead, are: 1.5 micrograms per cubic meter, maximum arithmetic mean averaged over a calendar quarter.

PAMS The Environmental Protection Agency (EPA) has revised the ambient air quality surveillance regulations in Title 40 Part 58 of the Code of Federal Regulations (40 CFR Part 58) to include provisions for enhanced monitoring of ozone, oxides of nitrogen, volatile organic compounds (VOCs), selected carbonyl compounds, and monitoring of meteorological parameters. The revisions require States to establish Photochemical Assessment Monitoring Stations (PAMS) as part of their existing State Implementation Plan (SIP) monitoring networks in ozone non-attainment areas classified as serious, severe, or extreme. The principal reasons for requiring the collection of additional ambient air pollutant and meteorological data are the lack of successful attainment of the National Ambient Air Quality Standard (NAAQS) for ozone, and the need to obtain a more comprehensive air quality data base for ozone and its precursors. Analysis of the data will help the EPD understand the underlying causes of ozone pollution, devise effective controls, and measure improvement.

1998 Air Toxics Monitoring Results Toxic air pollutants are also referred to as air toxics or hazardous air pollutants (HAPs). They are generally defined as those pollutants that are known or suspected to cause serious health problems. "Routine" toxic air pollutants are emitted by a variety of industrial sources and motor vehicles. In addition to routine releases, sudden accidental air releases of toxics potentially threaten many Americans. In response to public concern over the quality of Georgia's air, the Environmental Protection Division began an ambitious project in 1997 to establish, over the course of several years, nineteen sites to monitor non-criteria metals, semi volatiles, volatiles and carbonyl compounds. In 1998 there were a total of nine sites in nine counties monitoring for noncriteria pollutants. The following tables are the results of that monitoring

TYPES OF SAMPLING METHODS

LEAD (Manual) Samples are collected on 8" x 10" pre-weighed fiberglass filters with a high-volume sampler for 24 hours. Atomic absorption analysis is then performed on the samples

SULFUR DIOXIDE (Continuous) Continuous analysis for sulfur dioxide is accomplished with the use of pulsed fluorescence (U.V. Light) method.

NITROGEN DIOXIDE (Continuous) Continuous analysis for nitrogen dioxide is accomplished with the use of ozone phase chemiluminescent method.

CARBON MONOXIDE (Continuous) Continuous analysis for carbon monoxide is accomplished with the use of non-dispersive infrared analysis and gas filter correlation methods.

OZONE (Continuous) Continuous analysis for ozone is accomplished with the use of U.V. photometric method.

PARTICULATE MATTER 10 MICRON (PM-2.5) Samples are collected on Teflon filters with a PM-2.5 sampler for 24 hours. Gravimetric analysis is performed on all samples after collection.

PARTICULATE MATTER 10 MICRON (PM-10) Samples are collected on microquartz fiber filters with a PM-10 sampler for 24 hours. Gravimetric analysis is performed on all samples after collection.

ACID PRECIPITATION Samples are collected weekly and analyzed gravimetrically and also for acidity and conductivity. Further analyses are performed for selected compounds.

PAMS VOC ANALYSIS During June, July, and August samples are analyzed hourly using a gas chromatography unit using a Flame Ionization Detector (FID). Throughout the year, a 24 hour integrated sample is taken and analyzed in a State Laboratory.

PAMS Carbonyl Analysis During June, July, and August four integrated three hour samples are taken every third day. In addition throughout the year, a 24 hr integrated sample is taken once every sixth day and analyzed in a State Laboratory. Toxic Carbonyl Analysis Once every 12 days a sample is collected on a DNPH coated paper cartridge for 24 hours. Liquid chromatographic analysis is performed on the samples in a State Laboratory. Toxic Metals Analyses Once every 12 days a sample is collected on 8" x 10" pre-weighed quartz filters with a high volume sampler for 24 hours. ICP analysis is then performed on the samples in a State Laboratory. Toxic Semi-volatiles Analyses Once every 12 days a sample is collected on a sandwiched polyurethane foam plug and XAD adsorbent resin with a high volume sampler for 24 hours. Gas chromatographic analysis is then performed on the samples in a State Laboratory. Toxic Volatile Organic Compounds Once every 12 days a sample is collected in an evacuated SUMMA passivated canister. The canister is sampled for 24 hours and pressurized. An analysis is performed at a State Laboratory.
