Asbestos is a naturally occurring mineral found in several forms and because of its temperature-resisting properties, flexibility, and strength, it was widely used in the construction industry, automobile industry, and textile industry. Asbestos becomes dangerous when it crumbles and breaks releasing fibers that can cause asbestosis and certain types of cancer. Since the effects of asbestos exposure often do not appear until years later, there is concern in the United States over the presence of asbestos in older buildings, particularly schools. This guide lists materials on the uses and health problems associated with asbestos. As the name implies it is not a comprehensive bibliography but is designed to put the reader "on target." (PR)
