Natural Air Pollutants
Air pollution does not consist entirely of man-made substances. Many pollutants are released directly from natural sources, and some pose as much of a health hazard as man-made substances. These "natural" pollutants include radon, pollen, and mold spores. For more information on radon, contact the Chattanooga-Hamilton County Health Department at (423) 209-8110 or the state's Radon Hotline at 1-800-232-1139.
