Ambient Air Monitoring Ambient air monitoring in Georgia provides information on measured concentrations of criteria and non-criteria pollutants at selected locations. Criteria pollutants are those 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 58 monitors at 46 locations in 23 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). During 1996 the network contained 14 NAMS, 25 SLAMS, 19 SPM stations and 4 PAMS stations.
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-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 PM10. 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 24-hour concentrations of PM10, 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 PM10 levels, and small decreases in lung function take place when children are exposed to lower 24-hour peak PM10 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 24-hour 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 24hour 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 24-hour 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 24-hour 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. Air Quality Levels: EPA recently revised the ozone standard for areas of the state which are outside the Atlanta non-attainment area. For these areas, the 1-hour ozone standard was replaced with an 8-hour average ozone standard. The air quality standard for ozone, which is designed to protect public health with an adequate margin of safety, is 0.08 ppm, averaged over eight hours. EPD is required to issue a public alert when ozone levels reach 0.12 ppm, a public warning when ozone levels reach 0.40 ppm, and a declaration of public emergency at 0.50 ppm. The significant harm level, at which serious and widespread health effects occur among the general population, is 0.60 ppm of ozone, averaged over two hours.

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. Air Quality Levels: The air quality standard for CO, which is designed to protect public health with an adequate margin of safety, is 9 parts per million, averaged over 8 hours. EPD is required to issue a public alert when CO levels reach 15 ppm, a public warning when CO levels reach 30 ppm, and a public declaration of emergency at the level of 40 ppm. The significant harm level, at which serious and widespread health effects occur to the general population, is 50 ppm of CO.

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. Air Quality Levels: National primary and secondary ambient air quality standards for lead and its compounds, measured as elemental, 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.

PHOTOCHEMICAL ASSESSMENT MONITORING Carbonyl Compounds
Determination of ambient concentrations of carbonyl compounds is a requirement of 40 CFR Part 58, Subpart E, enhanced ozone network monitoring programs. Carbonyl compounds have been shown to contribute to the formation of photochemical ozone. Formaldehyde, acetaldehyde, and acetone are specifically required target compounds for PAMS; however, other carbonyl compounds may be added to the target list consistent with individual program objectives. The methodology used to accomplish carbonyl compounds monitoring provides sensitive and accurate measurements of carbonyl compounds and involves sample collection and analysis procedures. In this method, a cartridge(s) containing a solid sorbent is used to capture the target compounds.

Toxic Metals 1997 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 to establish, over the course of five years, twenty sites to monitor non-criteria metals which include arsenic, cadmium, chromium, nickel, and zinc. In 1997 beryllium, cobalt, lead, and selenium were added. There are six sites in six counties in the 1997 network. Currently there are no ambient standards established for these metals.

Ambient Air Monitoring Ambient air monitoring in Georgia provides information on measured concentrations of criteria and non-criteria pollutants at selected locations. Criteria pollutants are those 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 58 monitors at 46 locations in 23 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). During 1996 the network contained 14 NAMS, 25 SLAMS, 19 SPM stations and 4 PAMS stations.
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-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 PM10. 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 24-hour concentrations of PM10, 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 PM10 levels, and small decreases in lung function take place when children are exposed to lower 24-hour peak PM10 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 24-hour 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 24hour 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 24-hour 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 24-hour 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. Air Quality Levels: EPA recently revised the ozone standard for areas of the state which are outside the Atlanta non-attainment area. For these areas, the 1-hour ozone standard was replaced with an 8-hour average ozone standard. The air quality standard for ozone, which is designed to protect public health with an adequate margin of safety, is 0.08 ppm, averaged over eight hours. EPD is required to issue a public alert when ozone levels reach 0.12 ppm, a public warning when ozone levels reach 0.40 ppm, and a declaration of public emergency at 0.50 ppm. The significant harm level, at which serious and widespread health effects occur among the general population, is 0.60 ppm of ozone, averaged over two hours.

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. Air Quality Levels: The air quality standard for CO, which is designed to protect public health with an adequate margin of safety, is 9 parts per million, averaged over 8 hours. EPD is required to issue a public alert when CO levels reach 15 ppm, a public warning when CO levels reach 30 ppm, and a public declaration of emergency at the level of 40 ppm. The significant harm level, at which serious and widespread health effects occur to the general population, is 50 ppm of CO.

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. Air Quality Levels: National primary and secondary ambient air quality standards for lead and its compounds, measured as elemental, 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.

PHOTOCHEMICAL ASSESSMENT MONITORING Carbonyl Compounds
Determination of ambient concentrations of carbonyl compounds is a requirement of 40 CFR Part 58, Subpart E, enhanced ozone network monitoring programs. Carbonyl compounds have been shown to contribute to the formation of photochemical ozone. Formaldehyde, acetaldehyde, and acetone are specifically required target compounds for PAMS; however, other carbonyl compounds may be added to the target list consistent with individual program objectives. The methodology used to accomplish carbonyl compounds monitoring provides sensitive and accurate measurements of carbonyl compounds and involves sample collection and analysis procedures. In this method, a cartridge(s) containing a solid sorbent is used to capture the target compounds.

Toxic Metals 1997 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 to establish, over the course of five years, twenty sites to monitor non-criteria metals which include arsenic, cadmium, chromium, nickel, and zinc. In 1997 beryllium, cobalt, lead, and selenium were added. There are six sites in six counties in the 1997 network. Currently there are no ambient standards established for these metals.

Acid Precipitation 1998 Network

Acid precipitation was monitored in 6 counties in 1998. The Air Protection Branch operated 3 of these sites and the Georgia Forestry Commission and University of Georgia operated the remainder. There are no national or state standards for acid precipitation. A fiveyear analysis reveals no obvious trends.

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-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
NITRIC OXIDE Continuous analysis for nitric oxide is accomplished with the use of ozone phase chemiluminescent method.
OXIDES OF NITROGEN Continuous analysis for oxides of nitrogen is accomplished with the use of ozone phase chemiluminescent method. (method number 074)

ACID PRECIPITATION Samples are collected weekly and analyzed gravimetrically and also for acidity and conductivity. Further analyses are performed for selected compounds. 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. CARBONYL During July and August samples are taken for three hours and analyzed at a State Laboratory. Throughout the year a 24 hour integrated sample is taken and analyzed in a State Laboratory.
