The Six Criteria Pollutants:
1. Particulate Matter (PM): This refers to tiny particles suspended in the air, such as dust, soot, and smoke. These particles can originate from various sources, including industrial processes, vehicle emissions, and natural sources like wildfires. Inhalation of particulate matter can lead to respiratory problems and other health issues.
2. Sulfur Dioxide (SO2): This pollutant is primarily emitted from power plants and industrial facilities that burn fossil fuels containing sulfur compounds. Sulfur dioxide is a major contributor to acid rain and can also cause respiratory problems in humans.
3. Nitrogen Oxides (NOx): NOx emissions mainly come from burning fossil fuels at power plants, vehicles, and industrial processes. These pollutants contribute to the formation of smog and ground-level ozone, which can have adverse effects on human health, particularly on the respiratory system.
4. Carbon Monoxide (CO): Carbon monoxide is a colorless and odorless gas produced by burning fossil fuels. It is primarily emitted from vehicle exhausts and industrial processes. High levels of carbon monoxide can be harmful, as it reduces the amount of oxygen carried by the blood, leading to various health problems.
5. Lead (Pb): Lead emissions primarily result from industrial processes and the combustion of leaded gasoline, although leaded gasoline has been largely phased out in the United States. Lead exposure can cause a wide range of health issues, particularly in children, including developmental delays and neurological damage.
6. Ozone (O3): Ozone is a gas that occurs naturally in the Earth’s upper atmosphere and protects us from the sun’s harmful ultraviolet rays. However, at ground-level, ozone is formed by the reaction of volatile organic compounds (VOCs) and nitrogen oxides (NOx) in the presence of sunlight. Ground-level ozone can cause respiratory problems, especially for individuals with lung conditions.
These six pollutants have been identified as significant contributors to air pollution and have detrimental effects on human health and the environment. The Clean Air Act sets specific standards for each of these pollutants and requires federal, state, and local governments to take actions to reduce their emissions.
So there you have it! A brief overview of the six criteria pollutants regulated under the Clean Air Act. Understanding these pollutants is crucial in our efforts to protect our environment and ensure clean and healthy air for all.
Thank you for joining me on this journey through environmental law. Stay tuned for more insightful articles!

Understanding the Six Criteria Pollutants Regulated under the Clean Air Act
The Clean Air Act is a federal law designed to protect and improve air quality in the United States. It sets guidelines and regulations for controlling air pollution, with the goal of ensuring clean and healthy air for all Americans. One of the key aspects of the Clean Air Act is the regulation of six criteria pollutants, which are substances known to have adverse effects on human health and the environment.
These six criteria pollutants, also known as “criteria air pollutants,” were identified by the U.S. Environmental Protection Agency (EPA) as the most common and harmful air pollutants. The EPA established National Ambient Air Quality Standards (NAAQS) for these pollutants, which serve as benchmarks for permissible levels of pollution in the air. Meeting these standards is essential for maintaining good air quality and protecting public health.
The six criteria pollutants regulated under the Clean Air Act are:
Particulate matter refers to tiny solid particles and liquid droplets suspended in the air. These particles can come from a variety of sources, including smoke, dust, and industrial emissions. They are classified based on their size, with PM10 referring to particles smaller than 10 micrometers in diameter and PM2.5 referring to particles smaller than 2.5 micrometers. Exposure to particulate matter can lead to respiratory problems, cardiovascular issues, and other health effects.
Sulfur dioxide is a gas that is primarily emitted from burning fossil fuels containing sulfur, such as coal and oil. It contributes to the formation of acid rain and can cause respiratory issues, particularly in individuals with asthma or other respiratory conditions.
Nitrogen dioxide is a reddish-brown gas that primarily comes from burning fossil fuels, especially in vehicles and power plants. It can contribute to the formation of smog and can cause respiratory problems, particularly in individuals with asthma or other lung conditions.
Carbon monoxide is a colorless, odorless gas that is produced by incomplete combustion of fossil fuels, such as gasoline, oil, and wood. It is primarily emitted by vehicles and can be harmful when inhaled in high concentrations. Carbon monoxide reduces the amount of oxygen that can be carried by the blood, leading to headaches, dizziness, and even death in extreme cases.
Ozone is a gas that is formed when nitrogen oxides (NOx) and volatile organic compounds (VOCs) react in the presence of sunlight. It plays a vital role in the Earth’s upper atmosphere as it protects us from harmful ultraviolet radiation. However, at ground level, ozone is a harmful air pollutant and a primary component of smog. Exposure to high levels of ozone can cause respiratory issues, particularly in individuals with asthma or other lung conditions.
Lead is a highly toxic metal that can cause severe health problems, especially in children. In the past, lead was commonly used in gasoline, paint, and other products. The Clean Air Act has significantly reduced lead emissions by limiting its use and regulating industrial processes that release lead into the air.
Understanding these six criteria pollutants and their regulation under the Clean Air Act is crucial for individuals, businesses, and organizations to ensure compliance with air quality standards. Failure to comply with these regulations can result in penalties and fines.
In conclusion, the Clean Air Act focuses on regulating the six criteria pollutants – particulate matter, sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone, and lead. Understanding these pollutants and their sources is vital for individuals and industries to take necessary measures to reduce emissions and protect air quality. Compliance with the Clean Air Act not only contributes to a healthier environment but also safeguards public health for generations to come.

The Clean Air Act, enacted by the United States Congress in 1970, is a comprehensive federal law that regulates air pollution in the country. This law empowers the Environmental Protection Agency (EPA) to establish and enforce regulations to protect public health and the environment. One of the key provisions of the Clean Air Act is the regulation of six specific pollutants, known as the EPA Regulated Criteria Pollutants. Understanding these pollutants is crucial for individuals and businesses to ensure compliance with the law and minimize their impact on air quality.
The six EPA Regulated Criteria Pollutants are:
Particulate Matter refers to a mixture of solid particles and liquid droplets present in the air. These particles can be emitted directly from various sources such as industrial processes, vehicles, and wildfires, or they can be formed through complex chemical reactions in the atmosphere. PM can vary in size, with particles smaller than 10 micrometers (PM10) and those smaller than 2.5 micrometers (PM2.5) being of particular concern due to their ability to penetrate deep into the lungs and cause respiratory problems.
Sulfur Dioxide is a gas that is primarily produced from burning fossil fuels containing sulfur, such as coal and oil. It is also emitted by industrial processes and certain industrial facilities. SO2 can cause respiratory issues, particularly in individuals with pre-existing respiratory conditions, and it can contribute to acid rain and the formation of fine particles in the atmosphere.
Nitrogen Dioxide is a reddish-brown gas that forms when nitrogen oxides (NOx) react with the atmosphere. It is primarily emitted from burning fossil fuels, including vehicles, power plants, and industrial facilities. NO2 can contribute to the formation of ground-level ozone, a major component of smog, and it can cause respiratory problems and lung damage.
Carbon Monoxide is a colorless and odorless gas produced by the incomplete combustion of fossil fuels and biomass. It is primarily emitted from vehicles, power plants, and industrial processes. High levels of CO can be dangerous, as it reduces the blood’s ability to carry oxygen to vital organs and tissues.
Lead is a toxic metal that can have serious health effects, particularly in children and pregnant women. It is primarily emitted from industrial processes, mining activities, and the combustion of leaded gasoline, although regulations have significantly reduced lead emissions in recent decades. Lead can cause damage to the nervous system, kidneys, and other organs.
Ground-Level Ozone, often referred to as smog, is not emitted directly into the air but forms when pollutants like NOx and volatile organic compounds (VOCs) react in the presence of sunlight. It is a major component of air pollution and can cause respiratory problems, reduce lung function, and exacerbate existing respiratory conditions such as asthma.
The EPA regulates these six pollutants because they have been found to have adverse effects on human health and the environment.
