Carbon Monoxide is a gas mainly emitted by vehicles or machinery that burn fossil fuels. It is one of the six air pollutants controlled by EPA's National Ambient Air Quality Standards (NAAQS).
As a result of EPA's regulatory efforts, levels of lead in the air decreased by 98 percent between 1980 and 2014. In 2008, EPA significantly strengthened the air quality standards for lead to provide health protection for at-risk groups, especially children, and protect aquatic and terrestrial ecosystems.
NO 2 primarily gets in the air from the burning of fuel. NO 2 forms from emissions from cars, trucks and buses, power plants, and off-road equipment. Nitrogen Dioxide (NO 2) is one of a group of gases called nitrogen oxides (NO x).

Ozone Pollution Ground level or "bad" ozone is not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight.

Particulate matter (PM), also known as particle pollution, is a complex mixture of extremely small particles and liquid droplets that get into the air. Once inhaled, these particles can affect the heart and lungs and cause serious health effects.
Sulfur Dioxide (SO 2) is one of a group of gases called sulfur oxides (SO x). The other gases in the group are much less common in the atmosphere . May 29, 2018 - EPA proposes to retain the primary SO 2 NAAQS.
SO 2 results from the burning of either sulfur or materials containing sulfur. Sulfur Dioxide (SO 2) is one of a group of gases called sulfur oxides (SO x). The other gases in the group are much less common in the atmosphere .
