Air Pollutants and Monitoring

Specific Air Pollutant Information

Each of these air pollutants have established methods to track their amounts present in the air we breathe (also called ambient air). Many of them involve specific regulations and laws to keep our health and environment safe.

In South Carolina, the U.S Environmental Protection Agency (EPA) establishes laws, standards, and regulations for states to follow. DHEC is responsible for maintaining the air quality in South Carolina.


Radon is a naturally occurring, radioactive gas. It forms when uranium breaks down in soil, rock and water. You cannot see, smell or taste radon. It can get into the air you breathe indoors, primarily from soil and water under your home and other buildings.
