Asbestos

Asbestos is a name actually describing a group of mineral silicates, five of which are shown below. It has been used in insulation, roofing, flooring, cements and automobile brake linings just to name a few. The most common form of asbestos is chrysotile, with amosite and crocidolite being next in line.

Asbestos can cause serious health problems. Three specific diseases - asbestosis (scarring of the lungs), lung cancer and mesothelioma (a cancer of the lining of the chest) - have been linked to asbestos.
