About Asbestos


What is asbestos?

The Agency for Toxic Substances and Disease Registry (ATSDR) states, "Asbestos occurs naturally in certain types of rock. Large amounts of asbestos in rocks can look like long fibers, but each asbestos fiber is too small to see with the naked eye. Asbestos fibers do not dissolve in water or evaporate. They resist heat and fire and cannot be broken down easily by chemicals or bacteria. Certain areas of the country have natural deposits of asbestos near the ground surface."

The World Health Organization states "All types of asbestos cause lung cancer, mesothelioma, cancer of the larynx and ovary, and asbestosis (fibrosis of the lungs).  Exposure to asbestos occurs through inhalation of fiber in air in the working environment, ambient air in the vicinity of point sources such as factories handling asbestos, or indoor air in housing and buildings containing friable (crumbly) asbestos materials."

The Environmental Protection Agency (EPA) tried to ban asbestos in 1989; however, the rule was overturned in a courtcase in 1991. Asbestos imports and use continue today.
