EXECUTIVE SUMMARY 

A. General Review 

2011 air quality data are summarized for the 

seven criteria pollutants: particulate matter 

less than 10 microns in diameter (PM10) and 

particulate matter less than 2.5 microns in 

diameter (PM2.5), sulfur dioxide (SO2), nitrogen 

dioxide (NO2), carbon monoxide (CO), ozone (O3), 

and lead (Pb). Data are also summarized for 

total suspended particulates (TSP). 

A section discussing Toxics monitoring projects 

conducted in 2011 is included. 

Trend studies are presented for three criteria 

pollutants: SO2, CO, and O3. 

Precision and accuracy data gathered through the 

quality assurance programs are also included. 

B. Discussion of Violations 

Violations of multiple-year, annual and short 

term air quality standards by county and 

pollutant are shown in Figures 3 through 18 and 

in Table 3. 

C. Conclusions 

1. In 2011 there were 36 PM10 monitoring sites and 45 

PM2.5 monitoring sites with 95 monitors 63 of which 

are Federal Reference Monitors, 25 continuous (5 of 

which are Federal Equivalent Monitors), and 14 

speciation. In 1987 there were 30 PM10 and no PM2.5

monitoring sites. Nearly all monitoring for 

particulate matter is conducted using PM10 and PM2.5

samplers. Monitoring for TSP has essentially been 
 ii 

discontinued. During 2011, 9 TSP sites reported 

data, down from 217 sites in 1987. Of those 9 sites 

all are monitoring for lead or other metals and 

also report TSP data. 

2. Sulfur dioxide levels in urban areas have dropped 

an average of 56.7% in the last ten years. There 

were no violations of the 3-Hour, 24-Hour or annual 

SO2 air quality standards in 2011. There are four 

counties that are in violation of the 1-Hour 

standard (2009-2011). 

3. No overall trend is indicated for the past several 

years for carbon monoxide. Figure 23 shows 

individual urban area trends. 

4. The relatively high lead concentrations sampled in 

Fulton and Cuyahoga Counties are the result of 

industrial source monitoring. 

5. Twenty-five counties are monitoring attainment of 

the 0.075 ppm eight hour ozone standard. There are 

eight counties with monitored non-attainment based 

on data for 2009 through 2011. This report uses the 

ozone standard in effect during 2011. 

6. No violations of air quality standards for nitrogen 

dioxide were recorded in 2011. 

7. No air pollution alerts were declared in 2011. 

D. The Ohio Network 

In 2011 there were a total of 283 monitors at 

126 sites reporting data. There were 13 carbon 

monoxide, 32 sulfur dioxide, 3 nitrogen 

dioxide, 52 ozone, 43 10 micron particulate 

(PM10), 119 2.5 micron particulate monitors 

(PM2.5) and 27 lead monitors. 

The only states with comparable or more 

monitors are California with 1487, Texas with 

316 and Pennsylvania with 297.

I. INTRODUCTION 

A. General 

 

A variety of substances are generated and released into the 

atmosphere by a multitude of manmade and natural sources. Those 

substances that may affect public health and welfare are 

regarded as "air pollutants". The U.S. EPA has established 

National Ambient Air Quality Standards (NAAQS) to safeguard the 

public health and welfare from selected air pollutants. The 

pollutants for which standards have been promulgated are: Sulfur 

Dioxide (SO2), Nitrogen Dioxide (NO2), Carbon Monoxide (CO), 

Ozone (O3), Lead (Pb), Particulate Matter ≤10 microns (PM10) and 

Particulate Matter ≤2.5 microns (PM2.5). The standards are 

ambient concentrations that are expressed in micrograms per 

cubic meter (μg/m3

) or parts per million (ppm) per duration (1 

hr., 3 hr., etc.) with a restriction (not to be exceeded or not 

to be exceeded more than once per year, etc.). Table 1 shows the 

NAAQS in effect at the end of 2011. 

In some cases, standards are separated into two parts: primary 

and secondary. The primary standard sets the level of air 

pollution above which human health is endangered. The secondary 

standard sets the level above which the welfare of citizens is 

endangered due to air pollution damage to crops, animals, 

vegetation and materials. 

This report contains a summary of measured high concentrations 

of the pollutants, selected statistics, including quality 

assurance of the data, and trend analyses for various areas in 

Ohio. A brief description of the pollutants, the sources from 

which the pollutants originate and the adverse health effects of 

the pollutants and the monitoring methods, precede the tabulated 

pollutant concentrations. 

Ambient air is usually defined as air that is accessible to the 

general public. The air that is within (over) the fenced in or 

guarded areas of facility property is not ambient. 

Data for this report were collected by Ohio EPA, local air 

pollution control agencies and private industry. An indication 

of the accuracy of data from each reporting organization is 

located in a separate section on Quality Assurance. 

B. Development of the Ohio Air Monitoring System 

Society's concern about air pollution brought about the first 

national law, the Clean Air Act of July 14, 1955. This Act and 

its subsequent amendments first encouraged, and then authorized, 

grants to help finance the establishment of state and local air 

pollution control programs. 
2 

In 1963, aided in part by this federal program, the Ohio 

Department of Health established the Ohio Air Sampling Network 

(OASN) with 21 monitoring sites. The OASN was designed to 

measure the levels of "Total Suspended Particulate" (TSP) 

throughout the state. 

The Clean Air Act Amendments of 1970 mandated the promulgation 

of the NAAQS and delegated authority to develop plans for their 

attainment to the individual states. To oversee the provisions 

of this Act, the U.S. EPA was formed in February of 1972 by 

Presidential Order. 

After proposing standards for the criteria air pollutants, the 

U.S. EPA worked with Ohio to set up the State Implementation 

Plan (SIP) which included a detailed air monitoring program for 

the original six criteria pollutants: TSP, sulfur dioxide, 

carbon monoxide, nitrogen dioxide, lead and ozone. The SIP is a 

state's master plan for achievement of the NAAQS. The SIP 

contains detailed provisions for reducing concentrations of each 

of the regulated pollutants, where necessary, to achieve and 

maintain the NAAQS. 

In October 1972, Ohio EPA was established by State law (Ohio 

Revised Code Section 3745.01) and the air monitoring program was 

significantly enlarged. Many local air pollution control 

agencies and private industries participated in this program. 

See Figure 1 for the location of the five districts and the nine 

local air agencies currently supporting the air program. 

In 1980, the U.S. EPA and Ohio EPA established and designated 

certain portions of Ohio's network to be a part of the National 

Air Monitoring Station (NAMS) network, created for the purpose 

of tracking national trends. In 1980, the US EPA also required 

that all sites produce data of adequate quality to meet 

monitoring objectives and adequate quantity to meet statistical 

and trend requirements. All NAMS sites were to meet these 

requirements beginning with 1981 data, and all other sites 

beginning with 1983 data. 

On January 1, 2011 U.S. EPA made changes to the designations of 

sites. The NAMS sites, used for national trends in 

concentrations was eliminated in favor of NCore sites, a much 

smaller network of sites with many more parameters per site 

monitored. There are three sites in Ohio, one each in 

Cincinnati, Cleveland and Preble Co. 
3 

On March 20, 1984, the U.S. EPA proposed a standard for 

inhalable particles of ten micrometers in diameter and smaller. 

To enable the states to begin collecting data without excessive 

delay the U.S. EPA provided the states with monitors in late 

1984. Ohio's field offices began collecting PM10 data during 1985 

and a network of sites was primarily located in urban areas. 

The PM10 standard was promulgated on July 1, 1987 and became 

effective on July 31, 1987. 

The U.S. EPA promulgated new particulate monitoring regulations 

and National Ambient Air Quality Standards on July 18, 1997. 

The new particulate standard is for particulate matter less than 

or equal to 2.5 micrometers in diameter. The first monitors 

began to collect data in January 1999. Monitors to determine the 

chemical makeup of the particulate were added in the year 2000 

and in 2001 hourly reading monitors were added. 

The one hour ozone standard was supplemented on July 18, 1997 

with an eight hour standard. The eight hour standard is a three 

year average of the fourth highest daily eight hour averages. 

The level of the standard was set at 0.08 ppm which was not to 

be exceeded. 

In 2001 The United States Supreme Court found U.S. EPA’s 

previously proposed implementation plan for ozone unlawful and 

further held that, in the setting of a standard for ozone 

pursuant to Section 109 of the Clean Air Act U.S. EPA must set 

air quality standards at the level that is “requisite”-no higher 

or lower than is necessary-to protect the public health with an 

adequate margin of safety. The Supreme Court then sent the case 

back to the D.C. Circuit Court of Appeals to review U.S. EPA’s 

subsequent actions. On March 26, 2002, that court upheld U.S. 

EPA’s revision of the ozone NAAQS, which had been published in 

the Federal Register by U.S. EPA as a proposal on November 14, 

2001. 

In March 2008 the 8-Hour ozone standard was changed to be less 

than or equal to 0.075 ppm as the three year average of each 

site’s annual fourth high 8-Hour average. The summary tables in 

this report use the new standard. 

In 2009 the standard for lead (Pb) was changed to 0.15 μg/m3

 as a 

three month average. This standard replaces the 1.5 μg/m3
4 

calendar quarter average. New monitors near presumed sources are 

to be operational on the first sampling day of January 2010. 

During 2011, more than 280 ambient air monitors were operated in 

Ohio. Table 2 enumerates the number and type of criteria 

pollutant monitors that were operated in the various District 

Office and Local Air Agency jurisdictions. 

The goals of the ambient monitoring program are to determine 

compliance with the ambient air quality standards, to provide 

real-time monitoring of air pollution episodes, to provide data 

for trend analyses, regulation evaluation and planning, and to 

provide information to the public on a daily basis concerning 

the quality of the air in high population areas, near major 

emission sources and in rural areas. 

C. Remote Ambient Data System 

The Remote Ambient-Air Data System (RADS) is a system for the 

automatic acquisition and transmission of data from a remote 

monitor to a central computer. Each continuous monitoring site 

operated by Ohio EPA's district offices is furnished with a data 

logger that is polled automatically at least once a day by the 

central computer in Columbus and hourly for the AIRNow web site. 

A major benefit of RADS is that the data can now be handled more 

quickly with fewer chances of error. Formerly the data was 

manually read from recorder strip charts, handwritten on a 

computer input form, keyed into the computer and then made 

available for retrieval. This process took three to four weeks. 

The data in the RADS computer is available for review by the 

district and central office staff on a daily basis. The 

individual sites can also be contacted through the data logger 

for instantaneous data and interrogated further by remote 

testing of zero-span for any parameter. This is particularly 

valuable when pollutant levels are, or may become, elevated, as 

during an air stagnation episode. 

RADS was installed during the fall of 1985 and went into 

operation on January 1, 1986. Local air agencies have automated 

their continuous monitors and Ohio EPA has expanded RADS to 

include the automation of the local air agencies' networks. 

Industrial networks will also be added. 
5 

RADS has been upgraded for remote access to the data by digital 

cellular wireless technology to telemeter data to the central 

computer. 

D. Data Availability on the Internet 

For the past several years Ohio EPA has provided ozone and PM2.5

data updates several times a day to the U.S. EPA for a public 

outreach web site where current data and data forecasts are 

displayed in the form of tables and maps. This web site can be 

viewed at: www.airnow.gov. From this site different states can 

be chosen to view forecasts of ozone and PM2.5 levels and to link 

to animated ozone concentration maps. 

As part of the AIRNow effort there is also a page that displays 

a map of North America that has sites that can be clicked upon 

for current environmental data. This page is updated frequently 

and is called Enviroflash at: www.enviroflash.info. 

 

Historical ambient air quality data can also be found at: 

www.epa.gov/airdata/. This site is a gateway to maps, reports 

and user selected data that reside in the U.S. EPA’s Air Quality 

System (AQS) database. 

For those with specific health concerns (asthma, heart disease) 

or who want general information for older adults, children or 

who are active outdoors and who want to compare the air quality 

of different counties or states, the U.S. EPA has a web site 

that allows comparisons at: www.epa.gov/aircompare/ . 

E. Designation of Air Quality Control Regions 

The fact that air pollution does not respect state boundaries 

was recognized in early control efforts. To effectively deal 

with pollution and attain the NAAQS, U.S. EPA, with advice from 

local governments and the public, divided the nation into areas 

called Air Quality Control Regions (AQCR's). Boundaries for each 

region were set by consideration of air pollution levels, 

population density, geography, and common meteorological 

conditions. While AQCR's may consist of parts of more than one 

state, each state has the authority to implement air quality 

standards only in its portion of the region. Portions of Ohio 

are included in a total of fourteen different AQCR's, each 

labeled numerically and by geographical description. Figure 2 

illustrates the boundaries of Ohio's AQCR's.

II. Summary of 2011 Air Quality Data 

The following pages, in a series of maps and tables, summarize 

the data presented in Section V of the report. 

Figures 3-14 indicate the highest annual and second highest 

concentrations for PM10, PM2.5, SO2, CO, and NO2, respectively, in 

each county where data were collected. Sites not meeting 

Federal regulatory requirements for data completeness1

 are marked 

with asterisks. 

Figure 15 indicates the second highest 1-Hour concentration of 

ozone recorded in each county. 

FIGURE 16 indicates the counties in which the highest reading 

ozone monitor recorded a three year average of fourth highest 

eight hour averages greater than the standard. 

Figure 17 indicates the three year average of the 4th high 8-Hour 

averages of ozone. The highest reading site was used. 

Figure 18 indicates the highest three-month average 

concentration of lead in each county where data were collected. 

Table 3 gives a breakdown of air quality standard violations by 

county. 

A more detailed presentation of air quality data can be found in 

Section V of the report. 

 

 1The Federal averaging criteria for PM10 and PM2.5 monitors 

requires that at least seventy-five percent of scheduled samples 

are collected each quarter. Many intermittent monitors in Ohio 

run on a six-day sampling schedule (one daily reading every six 

days) yielding up to sixty-one samples per year. To meet 

averaging criteria for continuous (hourly) monitors, a monitor 

must have valid data for at least seventy-five percent of each 

calendar quarter, approximately 1655 hours. For a valid ozone 

monitoring day, the monitor must collect at least 18 hours of 

data or have an average that is greater than the standard.

III. Air 

Quality Trends 

Federal regulations promulgated in 1980 established a number of 

urban sites in Ohio as part of a national network for 

determining trends of the criteria pollutants. This network, 

called National Air Monitoring Stations (NAMS), required the 

exclusion (for purposes of trend studies only) of those urban 

sites not designated as NAMS. This requirement permits a more 

accurate comparison of trends in different areas of the nation. 

The NAMS group was easily integrated into Ohio's monitoring 

system starting with the 1980 data. 

SO2 TRENDS 

Data for SO2 continuous instruments in urban areas which met the 

NAMS siting requirements were used to generate Ohio SO2 trend 

studies for years 2002 through 2011. The resulting data, based 

on annual average SO2 concentrations, top chart, are plotted in 

Figure 19. Percent improvement is calculated using values 

derived from the method of "least squares". The bottom chart 

plots the 99th percentile value which is the new, short term, 1-

Hour, NAAQS for S02.

Ozone Trends 

Assessing progress towards the attainment of the ozone air 

quality standards is difficult because of the influence of 

meteorology on ozone levels. Differences in weather conditions 

can cause variations from year to year in both the NAAQS 

exceedances and the second highest 1-Hour ozone levels. 

High temperatures, brilliant sunshine and stagnant air 

contribute to high levels of evaporation from fuel storage 

tanks, fuel systems and auto refueling activities emitted by 

millions of cars and trucks. Also daily emissions of nitrogen 

oxides and hydrocarbons by millions of cars and trucks are a 

major contributor to low level ozone pollution during these 

atmospheric conditions. In the presence of sunlight, 

hydrocarbons and nitrogen oxides create high levels of groundlevel ozone. 

One Hour Data: 

Information is presented from eight metropolitan areas in Ohio 

for the period of 2002 through 2011. Figure 20 is a bar chart 

which shows, for each year, the second highest 1-Hour average. 

In an area where ozone is monitored at several sites, the site 

with the highest second high for each year was used which may be 

a different site from year to year. 

Eight Hour Standard: 

Eight metropolitan areas are presented with the three year 

average of the 4th highest 8-Hour daily ozone averages for the 

years 2002 through 2011. The year listed is the last year of the 

three year period. Figure 21 is a bar chart with those 

concentrations. The ambient air quality standard is a three year 

average of the fourth high 8-Hour averages, that concentration 

must be less than or equal to 0.075 parts per million (75 parts 

per billion) for an area to be in compliance with the standard. 

The monitor with the highest 4th high in each three year period 

was used, not necessarily the same monitor for all years. 

The three year averages for each site in Ohio are listed in the 

ozone portion of: Section V. AIR QUALITY DATA 2011.

IV. QUALITY ASSURANCE PROGRAM 

A. GENERAL 

Air monitoring data collected by State and Local Air Monitoring 

Stations (SLAMS)are required to meet Quality Assurance guidance 

in Appendix A of 40 CFR Part 58. That appendix specifies the 

minimum quality system requirements for SLAMS data for the 

pollutants SO2, NO2, O3, CO, Lead, PM2.5, and PM10. 

Air monitoring agencies are required to have a quality system in 

place. The quality system is the means by which an organization 

manages the quality of the monitoring data it produces in a 

systematic, organized manner. It provides a framework for 

planning, implementing, assessing and reporting work performed 

by an organization. It provides for required quality assurance 

and quality control activities. A quality system includes an 

overall Quality Management Plan and specific Quality Assurance 

Project Plans for the pollutants measured. 

For air monitoring data the measurements of accuracy and 

precision are integral to the quality assurance and quality 

control of the data. Accuracy is defined as the degree the 

measurement is close to the true value of the parameter 

measured. Precision is defined as the repeatability of the 

measurements. 

B. Accuracy and Precision Requirements 

Accuracy requirements for manual Lead, PM10 and PM2.5 samplers and 

continuous PM10 and PM2.5 monitors include audits of the flow rate 

of each sampler compared to a known flow rate at least once 

every 6 months. For continuous monitors for SO2, NO2, O3, and CO, 

quarterly audits of at least 25% of the analyzers are 

recommended. One audit per monitor per calendar year is 

required. During the audits the analyzers are tested with a gas 

in three specific concentration levels. 

Precision requirements for Lead, PM10 and PM2.5 are met by 

selecting sites in areas of expected highest concentration for 

side-by-side (collocated) sampling. Duplicate samples for 

comparison purposes are collected on an every 12-day schedule 

although it may be more frequent. Each PM2.5 sampler or continuous 

PM2.5 monitor should have a quality control flow rate 

verification each month. Each Lead and PM10 sampler should have a 

flow rate verification every quarter. For continuous SO2, NO2, O3, and CO monitors the determination of precision is by a onepoint quality control check against a gas of known concentration 

at least once every two weeks for each analyzer. The analyzers 

are operated in the normal sampling mode during this check. 
40 

The accuracy audit data and the precision data are collected by 

local and state agencies and reported to the US EPA Air Quality 

System (AQS) within 90 days of the quarter when they were 

performed. 

C. The Statistics of Accuracy and Precision 

Statistical calculations are available from reports in the Air 

Quality System as calculated from the reported accuracy and 

precision data. Calculations are as shown in Appendix A of 40 

CFR 58. The results of those data are available to the reporting 

organization that collected the data and to other AQS data 

users. Statistics that are available for 1-Point Quality Control 

include results for percent of data completeness, coefficient of 

variation (CV) and bias for each analyzer plus a combined 

summary for the reporting organization for the pollutant. 

Results of collocated data for PM10 and for PM2.5 include the 

number of collocated data pairs, the percentage completeness and 

the coefficient of variation. For manual PM10 and PM2.5 accuracy 

the number of flow rate audits, the percent completeness and the 

lower and upper confidence limits are included. 

For accuracy statistics the summary results that are included in 

the accompanying tables for SO2, NO2, CO and O3 include 1-Point 

Confidence Limits and percentage of data between confidence 

limits. 

In general lower numbers for the coefficient of variation are 

desirable because indicates more consistency of the test 

measurements. For SO2, NO2 and CO 10% is the CV upper target. For 

those pollutants 10% is the bias target also. For O3 7% is the CV 

target and 7% for bias. For PM2.5 10% or less is the target for 

precision. For PM2.5 accuracy audits less than 5% for design is 

the upper limit. For QA statistics 100% data completeness is 

desired. 

Tables 5-8 give summaries of the percent completeness, 

coefficient of variation and bias for precision and 1-point 

confidence limits and percent of data between confidence limits 

for accuracy for each reporting organization in the state, for 

SO2, NO2, CO and O3 monitors. 

Tables 9-11 give summaries of number of duplicate samples, 

percent completeness and coefficient of variation for precision 

and percent completeness and lower and upper confidence limits 

for accuracy for PM10, PM2.5 and Lead.

Total Suspended Particulate (TSP) 

Total suspended particulate matter is defined as any liquid 

(aerosol) or solid substance found in the atmosphere. Particles 

larger than approximately 100 microns in diameter settle rapidly 

due to gravity and are not considered suspended particulates. 

Fly ash, process dusts, soot and oil aerosols are all common 

forms of suspended particulate matter. The major sources of 

particulate pollution are industrial processes, electric power 

generation, industrial fuel combustion, and dust from plowed 

fields, roadways, or construction sites. Particulate pollution 

causes a wide range of damage to materials, as well as limiting 

visibility and reducing the amount of sunlight reaching the 

earth. Components of particulates may be harmful, such as 

sulfates, nitrates and metals. The major adverse health effects 

on humans are related to damage to the respiratory system 

through interference with the lung's natural cleansing process. 

Such adverse health effects are dependent, in a general sense, 

upon (1) the concentration, size and chemical composition of the 

particles of which the TSP consists and (2) the concentration 

and composition of any pollutant gases in combination with it. 

Particles greater than 10 microns in diameter can rarely 

penetrate below the larynx and, therefore, are less likely to 

damage the respiratory system. Particles less than 6 microns in 

diameter can penetrate the bronchial passage and those of less 

than 1 micron in diameter can usually penetrate and be deposited 

in the capillaries and alveoli of the lungs. (I.M. Campbell, 

Energy and the Atmosphere: A Physical Chemical Approach, John 

Wiley & Sons, LTD., 1977). 

An inhaled particle may exert a toxic effect in one or more of 

the following four ways: (1) the particle may be intrinsically 

toxic because of its inherent chemical or physical 

characteristics; (2) the particle may interfere with one or more 

of the mechanisms that normally clear the respiratory track; (3) 

the particle may act as a carrier of an absorbed toxic 

substance; or (4) the particle may act as a carrier of an 

absorbent toxic substance. 

It is difficult to obtain direct relationships between exposures 

to various concentrations of TSP and resulting effects upon 

human health because of the problems of isolating the effects of 

TSP from those of other environmental pollutants and of 
52 

reproducing in the laboratory the exact conditions that prevail 

in the ambient air. Also, it has been observed that exposure to 

TSP in combination with other pollutants such as sulfur dioxide 

(SO2) produces more severe effects than does exposure to each 

pollutant separately. Nevertheless, statistical analyses of 

morbidity and mortality data do indicate a relationship between 

increased TSP concentrations and increased numbers of hospital 

and clinic admissions for upper respiratory infections, cardiac 

diseases, bronchitis, asthma, pneumonia, emphysema and the like. 

(Air Pollution: Its Origin and Control, Harper & Row, 1976.) 

TSP ceased to be a criteria pollutant on August 1, 1987, having 

been replaced by PM10. 

Starting in 1987 TSP sampling was gradually replaced by ten 

micron particulate sampling (PM10). There were over 200 TSP 

monitors in 1987. In 2011 there were 9 monitors reporting TSP 

data, all are used for lead or other metals monitoring. In July 

1997 the U.S. EPA promulgated regulations adding a National 

Ambient Air Quality Standard for 2.5 micron particulate matter 

(PM2.5). The PM2.5 monitors supplement and partially replace the 

PM10 network. They started collecting data in January 1999. 

Sampling Method 

 

TSP is measured by the high-volume air sampler method. This 

instrument draws measured volumes of air through a pre-weighed 

glass fiber or quartz filter for a specific time (normally 24 

hours). Particulate matter in the air is trapped on the filter, 

which is then re-weighed to determine the mass of the 

particulates collected. Results are reported as micrograms of 

particulate matter per cubic meter of air (μg/m3

). Normal 

sampling is done intermittently with 24-hour samples taken once 

every six days.

Particulate Matter (<10μ, PM10) 

On July 1, 1987, the U.S. EPA promulgated revisions to the 

National Ambient Air Quality Standards for particulate matter. 

The primary standard includes only those particles with an 

aerodynamic diameter smaller than or equal to a nominal 10 

micrometers. This standard is referred to as the PM10 standard 

(particulate matter <10 micrometers). From July 1987 until July 

18, 1997 the annual standard was 50 μg/m3

 annual arithmetic mean 

(average over three years' data). The 24-hour standard, not to 

be exceeded more than once, was 150 μg/m3. The standard is that 

the 24-hour level of 150 μg/m3

 is not to be exceeded more than 

once per year averaged over three years. 

The annual standard was retained until the changes to the 

particulate standards that became effective on December 18, 2006 

when the 24-Hour standard was retained and the annual standard 

was revoked. 

The standards were changed in July 1997, when the PM2.5 standard 

was promulgated. Changing the standard from TSP to PM10 and then 

adding PM2.5 was due to research findings concerning particle 

size. Particulate matter can harm body tissue such as the 

linings of the nose and throat and the lungs by simple 

mechanical irritation. Nasal hairs and sneezing are the body's 

natural defenses against some of the relatively large particles 

(15-100 microns). However, small particles can slip past these 

defenses and penetrate deep into the lungs where they can damage 

lung tissues. 

Because of the final action to set the fine particulate 

standards by U.S. EPA to replace TSP, the Ohio Air Monitoring 

Network was expanded to include 21 PM10 sites in 1986, to 45 in 

1988 and to a high of 91 in 1997. During the year 2011 monitors 

were operated at 36 sites. 

Samples are taken each weekday at urban sites used in reporting 

the Air Quality Index (AQI). 
Note: The * indicates that the mean does

not satisfy summary criteria.

Particulate Matter <2.5μ (PM2.5) 

On July 18, 1997, the U.S. EPA promulgated revisions to the 

National Ambient Air Quality Standards for particulate matter. 

The primary standard includes only those particles with an 

aerodynamic diameter smaller than or equal to a nominal 2.5 

micrometers. This new standard is referred to as the PM2.5

standard (particulate matter <2.5 micrometers). 

The annual standard is 15μg/m3 annual arithmetic mean (average 

over three consecutive years' data). The 24-hour standard is met 

when the 98th percentile concentration averaged over three 

consecutive years, is less than or equal to 35μg/m3. 

The 24-Hour National Ambient Air Quality Standard was changed 

from 65μg/m3

 to 35μg/m3 effective in December 2006. 

This revision to the particulate matter program is due to 

research findings concerning particle size. Particulate matter 

can harm body tissue such as the linings of the nose and throat 

and the lungs by simple mechanical irritation. Nasal hairs and 

sneezing are the body's natural defenses against some of the 

relatively large particles (15-100 microns). However, small 

particles can slip past these defenses and penetrate deep into 

the lungs where they can damage lung tissues. 

Because of the final action to set the fine particulate 

standards by U.S. EPA to supplement PM10, the Ohio Air Monitoring 

Network had a peak of 52 sites in 2008. There were 45 PM2.5 sites 

in 2011. Those 45 sites have a total of 95 monitors reporting 

data. There are 25 continuous monitors of which 5 are Federal 

Equivalent Method monitors and 14 speciation monitors in 

addition to the 63 Federal Reference monitors. 

The Federal Reference and Federal Equivalent Method monitors are 

used to determine compliance with the National Ambient Air 

Quality Standards, the speciation monitors are used for analysis 

to determine the composition of the particulate and the 

continuous monitors are primarily used for the Air Quality Index 

and for “real time” reporting of particulate data to the public. 

Since most continuous and all speciation analysis monitors are 

not Federal Reference or Equivalent Methods those data are not 

used to determine compliance with the National Ambient Air 

Quality Standards. 
Note: The * indicates that the mean does

not satisfy summary criteria.

Sulfur Dioxide (SO2) 

Sulfur dioxide is a colorless gas formed through the combination 

of sulfur and oxygen during combustion. The major sources of SO2

are the burning of sulfur-containing fossil fuels (mainly coal), 

with lesser amounts caused by industrial processes such as 

smelting. Over 40% of the SO2 found in the ambient air is the 

result of human activities. 

The control of SO2 emissions from these sources is accomplished 

primarily by burning coal or oil with a relatively low sulfur 

content. Newer boilers may be equipped with flue gas 

desulfurization (FGD) systems that use a caustic solution to 

scrub SO2 from the exhaust gas stream. 

Sulfur dioxide is harmful because it can be converted to 

sulfuric acid (H2SO4) when it comes in contact with moisture, 

either in the atmosphere, on plants, materials, or in the lungs. 

Sulfur Dioxide can also be converted to a sulfate (SO4

2-) which 

as a particulate (aerosol) helps form acid rain and can also be 

a lung irritant. 

The presence of increased levels of SO2 in the atmosphere has 

been associated with a higher incidence of respiratory diseases, 

higher death rates, and property damage. 

Sampling Methods 

Sulfur dioxide is measured continuously by instruments using 

pulsed fluorescent techniques. 

Fluorescent analyzers irradiate an ambient air sample with 

ultraviolet light. Sulfur dioxide gas molecules absorb a portion 

of this energy, and then re-emit the energy at a characteristic 

wavelength of light. This light energy emitted by SO2 molecules 

is sensed by a photomultiplier tube and converted to an 

electronic signal proportional to the concentration of SO2

present. 

All concentrations for SO2 are given in parts per million (ppm). 

Reports for 1995 and earlier used the units 'micrograms per 

cubic meter’ (μg/m3) to report data. The primary units to report 

data were changed by U.S. EPA in May of 1996. 
69 

National Ambient Air Quality Standards 

On June 22, 2010 the U.S. EPA revised the NAAQS for SO2 by adding 

a 1-Hour standard which is the three year average of the 99th

percentile concentration in each year at each monitoring site. 

The level of the standard is 75 ppb which is not to be exceeded. 

The older NAAQS: Annual, 24-Hour and 3-Hour were retained. 
Note: The * indicates that the mean does

not satisfy summary criteria.

Nitrogen Dioxide (NO2) 

Nitrogen dioxide is a toxic gas formed in high temperature 

combustion processes, when nitrogen in the air is oxidized to 

nitric oxide (NO) or nitrogen dioxide (NO2). The major sources of 

NO2 are high temperature fuel combustion, motor vehicles, and 

certain chemical processes. 

Nitrogen dioxide has been associated with a variety of 

respiratory diseases through its ability to reduce cell immunity 

or resistance to bacteria and viruses. Nitrogen dioxide is also 

harmful due to its involvement in the production of 

photochemical oxidants such as ozone (O3). 

Sampling Methods 

Continuous monitoring of nitrogen dioxide is based on a 

chemiluminescent reaction between NO and O3. When these two gases 

react, light energy at a specific wavelength is produced. In the 

monitor, ambient air is drawn along two paths. In the first 

path, the air is reacted directly with ozone, and the light 

energy produced is proportional to the amount of nitric oxide in 

the air. In the second path, the air is reacted with ozone after 

it passes through a catalytic reduction surface. The reduction 

surface converts NO2 to NO and the light energy produced is a 

measure of the total oxides of nitrogen in the air sample. The 

electronic difference of these two signals yields the 

concentration of nitrogen dioxide. 

All concentrations for NO2 are given in parts per billion (ppb). 

National Ambient Air Quality Standards 

On February 9, 2010 the U.S. EPA revised the NAAQS for NO2 by 

adding a 1-Hour standard which is the three year average of the 

annual 98th percentile values. The level of the standard is 100 

ppb which is not to be exceeded. 

The older annual NAAQS of 53 ppb was retained.

Carbon Monoxide (CO) 

Carbon monoxide, a colorless and odorless gas, is the most 

abundant and widely distributed pollutant found in the lower 

atmosphere. It is produced by the incomplete combustion of 

carbon containing fuels, primarily in the internal combustion 

engine. About 95 to 98% of urban carbon monoxide comes from 

manmade sources, with transportation vehicles ranking as the 

largest source. 

The main effect of CO on human health involves its tendency to 

reduce the oxygen carrying capacity of the blood by binding 

chemically to hemoglobin, the substance that carries oxygen to 

the cells. This may lead to short-term impairment of mental 

processes. Exposure to concentrations as low as 10-15 ppm for 

several hours has affected time interval discrimination in test 

subjects, while exposures of 31 ppm under similar conditions 

have temporarily altered the function of the brain. 

Sampling Method 

Carbon monoxide is monitored continuously by analyzers that 

operate on the infrared absorption principle. Ambient air is 

drawn into a sample chamber and a beam of infrared light is 

passed through it. CO absorbs infrared radiation, and any 

decrease in the intensity of the beam is due to the presence of 

CO molecules. This decrease is directly related to the 

concentration of CO in the ambient air. A special detector 

measures the difference in the radiation between this beam and a 

duplicate beam passing through a reference chamber with no CO 

present. This difference in intensity is electronically 

translated into a reading of the CO present in the ambient air, 

measured in parts per million. 

National Ambient Air Quality Standard 

The NAAQS for carbon monoxide are a 1-Hour concentration of 35 

ppm which is not to be exceeded more than once per year and an 

8-Hour concentration of 9 ppm which is not to be exceeded more 

than once per year.

Ozone (O3) 

Ozone differs from other pollutants in that it is not directly 

emitted into the atmosphere from sources. Rather, it is created 

photochemically in the lower atmosphere by the reaction of 

volatile organic compounds and oxides of nitrogen in the 

presence of sunlight. For this reason, it is referred to as a 

secondary pollutant. Ozone is the predominant oxidant component 

of photochemical smog. 

In urban areas, emissions of nitrogen oxides and volatile 

organic compounds lead to the formation of ozone and other 

photochemical oxidants in the lower atmosphere. Nitrogen oxides, 

important in triggering the sequence of photochemical reactions, 

are emitted primarily from combustion sources such as the 

internal combustion engine, electric power generation units, and 

gas and oil-fired space heaters. Volatile organic compounds, 

important in sustaining the reactions, are emitted in the 

exhausts of gasoline, diesel and jet engines, through the 

evaporation of gasoline and solvents such as dry-cleaning 

fluids, and from industrial and non-industrial surface coating 

operations such as paint booths, from open burning, and other 

combustion sources. 

Although ozone is beneficial in the upper atmosphere, where it 

screens out ultraviolet rays from the sun, it is harmful in the 

lower atmosphere. Due to the role of temperature and sunlight in 

its formation, the largest concentrations occur during the 

summer months. Ozone irritates mucous membranes of the nose and 

throat, causes eye irritation, reduces resistance to respiratory 

infections, damages plants and contributes to the deterioration 

of materials. Individuals with asthma or disease of the heart or 

circulatory system experience symptoms when concentrations are 

above the air quality standards. 

Prior to July 1997 there was a one hour standard of 0.12 ppm 

with more than three exceedances being a violation of the 

standard. The one hour standard was revoked in 2006. 

The standard from July 1997 to May 27, 2008 was an eight hour 

average of 0.08 ppm with the fourth high eight hour average 

averaged in each year over three consecutive years. 

The current standard is a three year average of the fourth 

highest eight hour averages at each monitoring site. If that 
 77 

three year average is greater than 0.075 ppm (76 ppb or greater) 

a violation of the standard has occurred 

In 2001 The United States Supreme Court found U.S. EPA’s 

previously proposed implementation plan for ozone unlawful and 

further held that, in the setting of a standard for ozone 

pursuant to Section 109 of the Clean Air Act U.S. EPA must set 

air quality standards at the level that is “requisite”-no higher 

or lower than is necessary-to protect the public health with an 

adequate margin of safety. The Supreme Court then sent the case 

back to the D.C. Circuit Court of Appeals to review U.S. EPA’s 

subsequent actions. On March 26, 2002, that court upheld U.S. 

EPA’s revision of the ozone NAAQS, which had been published in 

the Federal Register by U.S. EPA as a proposal on November 14, 

2001. 

This report contains a printout of the one hour data and eight 

hour average data, as in previous reports, and printouts of the 

three year average of the fourth high eight hour averages 

calculated for each site in Ohio for the years 2009 through 2011 

and the four highest eight hour averages during 2011. A three 

year average was not calculated if one or more years had 

insufficient data. 

Sampling Methods 

Ozone is monitored continuously during our ozone season, April 

1st through October 31st using analyzers that operate on 

ultraviolet absorption techniques. 

Ozone absorbs ultraviolet light. Analyzers designed to measure 

ozone by ultraviolet photometry use this property. An air sample 

is drawn into the analyzer and irradiated with an ultraviolet 

light of 253.7 nanometers wavelength. The amount of light 

absorbed is related to the amount of ozone present. This is the 

type of monitor used by Ohio EPA and our Local Air Agencies. 

All concentrations for ozone are given in parts per million 

(ppm).

On the following pages are tables of ozone sites with the: 

Highest through fourth highest 1-Hour ozone values 

Highest through fourth highest 8-Hour ozone values 

Three year average of fourth highest 8-Hour ozone 

values (see NAAQS TABLE 1) 

First day in each year from 1992 that recorded an 

exceedance of the 1-Hour or 8-Hour standard with the 

number of sites and the total number of exceedances 

Last day in the year upon which an exceedance of the 

1-Hour or 8-Hour standard occurred with the number of 

sites and values listed

Lead 

Airborne lead in urban areas was once primarily caused by 

vehicles using leaded fuels. Sources of airborne lead now 

include lead smelting facilities, lead-acid storage battery 

manufacturing plants and other manufacturing operations. 

In the period 1978-1991 lead concentrations at traffic oriented 

sites dropped by over 90%, reflecting the removal of lead from 

gasoline. In March 1999 the U.S. EPA promulgated new rules for 

lead monitoring that eliminated the requirement for traffic 

oriented sites and emphasizes monitoring at industrial sources. 

We discontinued monitoring at traffic oriented sites after the 

first calendar quarter of 1999. 

In September 2008 the U.S. EPA changed the National Ambient Air 

Quality Standard for lead from 1.5 g/m3 as a calendar quarter 

average “not to be exceeded” to 0.15 g/m3

 as a running three 

month average. This much stricter standard is designed to 

provide increased protection to the public, particularly 

children. 

The new lead standard originally required increased monitoring 

at lead sources that reported emissions of greater than 1.0 ton 

per year. These source oriented sites were required to be in 

place and operating as of January 1, 2010. A revision to the 

lead standard promulgated on December 27, 2010 changed the level 

of emissions that required review for possible monitoring to 0.5 

tons per year. 

Lead monitoring is also required at NCore sites in Core based 

statistical areas (CBSAs) of 500,000 or more persons. There will 

be three sites in Ohio: Cincinnati, Cleveland and Dayton. 

Lead is a stable compound that can accumulate in the human body. 

Its health related effects include interference with the blood 

forming process and the normal functions of nervous and renal 

systems. Young children are the age group most susceptible to 

the adverse effects of lead.

Sampling and Analysis Method 

Lead concentrations in ambient air are determined by the 

reference method promulgated by U.S. EPA. Lead samples are 

collected as total suspended particulate matter (TSP) on glass 

fiber filters according to 40 CFR Part 50, Appendix B, the EPA 

Reference method for the Determination of Suspended Particulate 

Matter in the Atmosphere. These filters are then analyzed by 

the manual Equivalent method: EQL-0710-192, “Heated Nitric Acid 

Hot Block Digestion and ICP/MS analysis for Lead (Pb) on TSP 

High-volume filters”. In this method, one 3⁄4”x 8” portion or 

strip, of the TSP filter is dissolved in a solution of nitric 

acid, heated on a hot block, on which the solution is reduced to 

final volume for analysis. The extracted solution is then 

analyzed by inductively coupled plasma-mass spectrometry, 

(ICP/MS) to determine the amount of lead collected on the 

original filter. 

In the past a month's collection of filters was analyzed as a 

composite sample. Most sites collect so little lead that 

individual sampling days’ analysis would have lead 

concentrations below the detection limit of the methods used at 

the time. Some sites’ filters are still analyzed this way. Newer 

sites and sites that are being used to meet the new monitoring 

network requirements have individual sampling events (days) 

analyzed. 

Concentrations are reported in micrograms per cubic meter of air 

(μg/m3

).

AIR TOXICS MONITORING 

INTRODUCTION 

As part of its air quality monitoring program, Ohio EPA, 

Division of Air Pollution Control (DAPC) operates a network of 

air toxics monitors as part of a state wide Air Toxics 

Monitoring Program (ATMP). This Air Toxic sampling network is 

modeled after programs and methodologies recommended by U.S. 

EPA. The emphasis has been on urban toxics monitoring for 

volatile organic compounds and heavy metals. Brief sections 

describing the sampling and analytical procedures for the 

pollutants follow the introduction. 

1.) Main focus of the ATMP is on urban monitoring, looking for 

major risk areas where people live. In this effort sampling has 

concentrated on groups of compounds. 

volatile organic compounds (VOC), examples: 

 benzene, chloroform, styrene, toluene etc. 

heavy metals, examples: 

 arsenic, cadmium 

The majority of the sampling has been conducted at semipermanent monitoring sites where monitoring extends beyond a 6 

month period. The intermittent sampling stations at these types 

of sites have been dedicated to VOCs and heavy metals 

monitoring. See the list following the description of the 

volatile organic analysis method for the VOC target compounds. 

The list of target metals is included in the metals description 

section. 

Semi-permanent monitoring projects have been conducted in: 

 Cleveland - VOC - Urban, Metals - Urban 

 Middletown - VOC - Source, Metals - Source 

 Columbus - Metals - Urban, VOC - Urban 

 Marietta - Metals - Source 

 Delta - Metals - Source 

 East Liverpool - Metals - Source 

 Steubenville - VOC - Urban 

 Marion - Metals - Urban 

 Bellefontaine - Metals - Urban 

 Elmore - Metals - Urban 
96 

2.) Throughout 2011 DAPC has worked to expand sampling at semipermanent sites with an emphasis on smaller urban areas. Future 

sampling projects will involve additional sampling locations or 

reallocation of current resources to other locations. Expanded 

air toxics sampling will involve adding other parameters to 

existing sites. DAPC’s efforts will also include more efficient 

use of short term sampling. 

Past sampling efforts have included: 

 

Cross Media pollution monitoring Urban air toxics 

Great Lakes deposition monitoring Source monitoring 

Post-remediation Monitoring Complaint investigation 

Emergency Episode Monitoring Emissions verification 

During 2011 DAPC was involved in several minor monitoring 

projects throughout the state. However, due to the limited 

scope of these short term and grab sampling projects they are 

not included in the data summaries for this year. 

The sampling and analytical methods for VOCs and heavy metals 

are described below. 

VOLATILE ORGANIC COMPOUND SAMPLING AND ANALYSIS 

SAMPLING

A major component of the Air Toxics Monitoring Program is 

ambient sampling for volatile organic compounds (VOCs). These 

are compounds that are generally found in the vapor state. Some 

organic compounds can be chlorinated, (contain chlorine) or just 

hydrocarbons, (contain just hydrogen and carbon atoms). Most of 

the VOC samples were collected using a whole air sampling system 

that pumped ambient air into a stainless steel canister. The 

canister, which is evacuated prior to use, is a storage 

container which allows an air sample to be maintained virtually 

unchanged until it is analyzed. In addition to the pumped 

sampling method, a number of samples were collected using the 

vacuum of the canister to draw in an air sample. These, vacuumfilled “grab” samples usually take only a few minutes to collect 

and were useful for collecting transient odors or potentially 

high concentration samples. DAPC is now capable of collecting 

specific samples for 1, 3, 8 and 24 hours using this grab 

sampling method. 

Initially samples were collected sporadically, however as semi-
97 

permanent sites were established the sampling program has become 

more routine. With that, an attempt has been made to collect 

samples at least twice a month, with a sampling frequency 

consistent with the national air toxics monitoring schedule of 

once every 12th day, over a 24 hour period. The specific 

procedures for this type of sampling can be found in the U.S. 

EPA Compendium of Methods for the Determination of Toxic Organic 

Compound in Ambient Air in the section TO-14 

ANALYSIS 

The volatile tendency of VOCs allows them to be vaporized when 

heated, (if not already in that form) and to be injected into an 

analytical device called a gas chromatograph (GC). As a sample 

passes through a GC column, the various compounds separate out 

of the sample mixture. As the individual compounds exit the 

column, a detector records a response. That response is 

illustrated on a chromatogram as a peak. The area of each peak 

indicates the concentration of the compound. Compound 

identification is accomplished by comparing the retention times 

of the peaks on a chromatogram with those from a chromatogram of 

a known mixture of compounds. Retention time is the time it 

takes for a particular compound to reach the detector. As long 

as the analytical conditions remain the same, a compound from 

one analysis to the next will have the same retention time. 

The typical analytical system used for this study utilized a GC 

with a special detector called a mass spectrometer (MS). The 

combination, a GC/MS, can be used to analyze a sample by 

separating it into its individual components which are then 

broken down into mass fragments which form a fingerprint by 

which a compound can be identified. 

All of DAPC’s canister analyses were conducted at the Ohio EPA 

Division of Environmental Services (DES). The analytical 

procedures performed by the laboratory targeted an list of over 

60 VOCs for identification and quantitation. The following list 

includes the current parameters of the analytical target 

compounds list. Most of the target compounds have a detection 

limit of 0.2 ppbv. The Exceptions are Acetone, 2-Butanone, 

Carbon Disulfide, total m&p-Xylenes, which have limits 0.4 ppbv 

or higher depending of the sample concentration.

Beyond this list of compounds, additional compounds can be 

detected and tentatively identified during the analysis of VOC 

samples. If during the analysis, an unidentified compound of 

significant quantity, (greater than 0.2 ppb) exist in a sample 

it can be identified during the MS analysis. However, due to 

the uncertainty involved with the identification of these 

additional, non-target compounds and the vast number of them 

detected they are not included in this report. 

As the technology and the methods improve and new techniques are 

developed, it is expected that the target compounds list will be 

periodically modified. It is also expected that the list will 

change as U.S. EPA’s emphasis on air toxics compounds changes. 

The following tables summarize the data from the routine 

canister samples collected during 2011. Throughout 2011 over 

170, 24-hour samples were collected at 6 permanent VOC 

monitoring sites.

HEAVY METALS SAMPLING AND ANALYSIS

SAMPLING 

Ambient air toxic monitoring on a routine basis for heavy metals 

(other than lead), by Ohio EPA DAPC, was initiated in 1989 and 

has continued. Since that time all of DAPC’s air filter samples 

have been analyzed by the Ohio EPA Division of Environmental 

Services (DES). A summary of the results can be found in the 

following tables. Sampling for heavy metals is conducted using 

a high volume total suspended particulate (TSP) sampler. With 

this sampler, particulate matter in the air is collected on a 

glass fiber filter. Sampling is done intermittently with 24-

hour samples collected once every six days. The operating 

procedures for lead can be found in the Code of Federal 

Regulations, 40 CFR, Part 50, Appendix G. These basic 

procedures are also used for the other metals. 

ANALYSIS 

For this report filters collected at each site were analyzed as 

a monthly composite. Typically there are 5 sampling days in 

which a filter is collected. From these individual filters one 

strip is cut and combined from strips from all the filters 

collected that month and analyzed as one sample for the month. 

These composite samples are acid extracted and then the 

resulting solution analyzed by the ICP/MS similar to the method 

used for the determination of Lead from TSP filters. 

SUMMARY OF ICP METHOD: The method measures element - emitted 

light by optical spectrometry. Samples are nebulized into an 

aerosol and transported to the plasma by the nebulizer argon 

flow. The first function of the high temperature plasma is to 

remove the solvent from, or desoluate, the aerosol, usually 

leaving the sample as microscopic salt particles. The next steps 

involve decomposing the salt particles into a gas of individual 

molecules (vaporization) that are then dissociated into atoms 

(atomization). The next plasma functions are Excitation and 

Ionization. The light emitted by the excited atoms and ions in 

the plasma is measured to obtain information about the sample. 

For coupling to mass spectrometry, the ions from the plasma are 

extracted through a series of cones into a mass spectrometer, 

usually a quadrupole. The ions are separated on the basis of 

their mass-to-charge ratio and a detector receives an ion signal 

proportional to the concentration.

HEAVY METALS PARAMETERS 

Historically lead was the NAAQS Criteria pollutant released from 

gasoline into the ambient air. Monitoring for it established 

the lead filter analysis monitoring program. Over the years 

DAPC added other metals to the filter analysis program. As lead 

was phased out of gasoline other metals have risen to greater 

concern. At one time it was cadmium and from one particular 

industry it was beryllium. But now Ohio is focused on manganese 

in several communities. However, trends continue to change and 

lead has once again become the driving pollutant for filter 

analysis. As the only metal that is Criteria Pollutant lead is 

the pollutant that drives the metals monitoring program. With 

the establishment of a new NAAQS for lead, 0.15 μg/m3 from the 

previous standard of 1.5 μg/m3 and the requirement to monitor 

near specific sources, lead has been re-established as a 

pollutant of concern. Since 2010 DACP has had all TSP sampler 

filters collected analyzed for lead. 

For this particular section the data collected is from the 

monthly composite samples collected and analyzed. All monthly 

composite particulate filter samples collected by DAPC are 

routinely analyzed for eight metals. 

 arsenic cadmium chromium beryllium 

 lead1 nickel zinc manganese 

From each sample, most parameters are analyzed using a very 

sensitive ICPMS analytical system which significantly lowers the 

detection limit from the standard ICP instrument. The following 

parameters, which are typically detected in higher 

concentrations, are still analyzed with the older ICP method. 

 

 Iron potassium zinc manganese 

 

Particulate mercury that can be detected from a glass or quartz 

fiber filter has been added to the parameter list for a number 

of samples from sites in communities with specific concerns 

about potential mercury sources. Mercury analysis for each 

sample is performed separately from the other metals. Total 

mercury is determined using a cold vapor method developed by 

DES.

Lead is the only parameter being monitored in the ATMP that has a National 

Ambient Air Quality Standard. See Section V, page 90, Lead.

FUTURE 

The long term air toxics monitoring goals of DAPC will focus on the 

requirements of the Clean Air Act (CAA), particularly Section 112, 

and will support the development of EPA’s Integrated Urban Air Toxics 

Strategy. In addition the air toxics monitoring efforts will 

incorporate relative elements of the mission and goals of DAPC to 

protect the environment for the benefit of all and to develop 

improved air toxics information. 

The current strategy of urban based monitoring has evolved over the 

years and the number of sites and locations have changed depending on 

resources and priorities. The major emphasis of existing sampling 

projects is to develop and establish cost effective, routine sampling 

and analysis procedures. U.S. EPA has provided the Compendium of 

Recommended Methods for the Determination of Toxic Organic Compounds 

in Ambient Air. Methods have been updated to allow for more uniform 

approaches for sampling and analyzing various groups of compounds. 

New methods have been developed and added for compounds not 

previously targeted. There is even a Compendium of Methods for the 

Determination of Air Pollutants In Indoor Air. Ohio EPA’s own air 

toxics monitoring capacity has been enhanced with the expansion of 

the air canister sample analysis capability by the Division of 

Environmental Services (DES). 

Future Goals of the division will be modified to be compatible with 

the National Air Toxics Assessment Network activities. The intent of 

this network is to provide measurements of ambient concentrations of 

air toxics at monitoring sites throughout the nation for the 

estimation of human and environmental exposure to air toxics, and the 

assessment of risk due to air toxics. 

As part of the current grant commitment to U.S. EPA, DAPC will 

continue its effort to submit future Air Toxics Data to the AQS 

Database. As part of that effort DAPC will compile all air toxics 

data collected in previous years so that it may eventually be 

submitted to AQS. DAPC has already made an effort to have all metals 

data submitted to AQS. 

An intermediate effort of DAPC will be to conduct follow-up sampling 

efforts for the U.S. EPA School Air Toxics Program. Some of these 

areas were a high priority before the EPA study and will continue to 

be until the situation is mitigated. One development of this program 

was the expanded role of district and local air agencies into air 

toxics sampling. 
121 

Modernization: 

DAPC will pursue information on new technology such as: 

 Continuous gas chromatography, mass spectrometry 

 DES has developed an ICP/MS method for lead to be equivalent to 

Manual Equivalent Method: EQL-0710-192 and it is used to analyze 

all standard metals parameters, (except manganese, mercury and 

zinc), from single filters. 

 Updates of the Compendium of Recommended Methods are available at 

the following: http://www.epa.gov/ttn/amtic/airtox.html and 

http://www.epa.gov/ttn/amtic/inorg.html and 

 Modernizing the Stainless Steel Canister inventory 

 Evaluate future training needs for Air Toxics Monitoring: 

 sampling methods, 

 analytical procedures,

VII. AIR QUALITY INDEX (AQI) 

There has been a daily reporting of ambient air quality in 

Ohio's major metropolitan areas in some form since 1971. A 

national Pollution Standards Index (PSI) was established in 1977 

to report air quality. This index was adopted by Ohio EPA's 

District Offices and the local air agencies (LAA's) to inform 

the public of daily air quality. 

In the summer of 1999 the PSI scale was revised and renamed the 

Air Quality Index (AQI). It was modified to add 2.5 micron 

particulate matter (PM2.5) and to accommodate the 8-Hour ozone 

standard. 

The AQI (see Table 13) is a uniform "scaling" of five 

pollutants: particulate (PM10 and PM2.5), sulfur dioxide, ozone, 

nitrogen dioxide, and carbon monoxide. The concentration level 

of each of these is calculated every day to determine the AQI. 

The pollutant with the highest AQI is reported to the media. 

When the AQI exceeds, or is expected to exceed, 100 in a major 

city, the agency concerned issues a "health advisory". When 

pollution levels exceed an AQI of 200 and are projected to 

persist, an "air pollution episode" exists and the Governor 

declares an "alert". This initiates mandatory cutbacks of 

emissions from specified facilities to alleviate the situation. 

If the AQI were to surpass 300, 400 or 500, progressively 

greater cutbacks would be implemented to reduce pollutants to an 

acceptable level. 

The AQI trend shows that Ohio's air quality has improved 

significantly. Although alerts were commonplace in the early 

1970's, none have happened in over twenty years, and the number 

of health advisories has been greatly reduced.

AQI Chart 

The accompanying table shows the AQI values for selected 

counties. It should be noted that the daily AQI values that are 

calculated and reported on a daily basis for cities in these 

counties may differ from those in the table. The daily AQI is 

based on a limited number of monitors (particularly PM10 and 

PM2.5). This table uses data from all Federal Reference Monitors 

in the county. From those data the highest AQI value is chosen 

for each day. 

The data in TABLE 14 is for the AQI in effect during 2011. 

The table gives a general representation of the relative air 

quality in these counties. There were no readings in the “very 

unhealthy” or “hazardous” categories.
