Ozone
Ozone is a highly reactive, colorless gas pollutant that is not typically emitted directly into the air by any one source. Instead, ozone is considered a secondary pollutant, which means that it is formed through complex chemical reactions of molecules in the air. Specifically, ground-level ozone is formed when nitrogen oxides (NOx) and volatile organic compounds (VOCs) chemically react in the presence of sunlight.
Spare the Air
SCDES Spare the Air
SCDES Spare the Air is a statewide education and outreach campaign led by the Bureau of Air Quality that advances public health and environmental well-being by improving air quality across South Carolina.
Asbestos
According to the EPA, asbestos is a naturally occurring mineral fiber in rock and soil. Because of its fiber strength and heat resistance, asbestos has been used in a variety of building construction materials for insulation and as a fire retardant.
