What Are the Major Air Pollutants Monitored and Regulated by the EPA?
The Environmental Protection Agency (EPA) monitors and regulates several key air pollutants to ensure air quality and protect public health.
These pollutants, known as criteria air pollutants, are regulated under the Clean Air Act due to their potential to cause harm to human health and the environment.
The EPA tracks these pollutants using the Air Quality Index (AQI), which provides a standardized way of reporting air quality.
The six criteria air pollutants monitored and regulated by the EPA are:
- Ground-Level Ozone (O₃): Formed when pollutants emitted by cars, power plants, industrial boilers, refineries, and other sources chemically react in the presence of sunlight. Ozone at ground level can cause respiratory problems and other health issues.
- Particulate Matter (PM10 and PM2.5): Consists of tiny particles suspended in the air, which can be inhaled and cause severe respiratory and cardiovascular problems. PM10 refers to particles with diameters of 10 micrometers or less, while PM2.5 refers to particles with diameters of 2.5 micrometers or less.
- Carbon Monoxide (CO): A colorless, odorless gas produced by burning fossil fuels. High levels of carbon monoxide can interfere with the body’s ability to transport oxygen, leading to various health issues, including cardiovascular problems.
- Sulfur Dioxide (SO₂): Emitted from fossil fuel combustion at power plants and other industrial processes. Sulfur dioxide can cause respiratory problems and contribute to the formation of acid rain, which can harm ecosystems.
- Nitrogen Dioxide (NO₂): Part of a group of highly reactive gasses known as nitrogen oxides (NOx), emitted from vehicles, power plants, and off-road equipment. Nitrogen dioxide can cause respiratory issues and contribute to the formation of ground-level ozone and fine particulate pollution.
- Lead (Pb): Historically common in gasoline and paint, lead emissions have significantly decreased due to regulatory efforts. However, lead still poses a risk in areas with industrial emissions and can cause severe health problems, particularly in children.
These pollutants are also monitored using the AQI, which includes ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide.
The AQI helps communicate how polluted the air currently is or how polluted it is forecasted to become, providing a standardized way of reporting air quality and helping people understand what actions they need to take to protect their health based on air quality levels.
