Asbestos, a group of chemically and physically distinct fibers, is one of the most notorious carcinogens in the lung and pleura. The National Institutes of Health in 1978 estimated that approximately 11 million individuals had been exposed to asbestos in the United States since
1940 (1). Although widely employed in World Wars I and II, the use of asbestos has undergone major changes in recent decades, with severe restrictions in most countries on amphiboles. In developed countries, with the exception of Japan, asbestos production is controlled or banned, while in developing countries, consumption has leveled off or increased (2). Between the 1940s and 1970s, asbestos was utilized exten-sively in insulation applications (primarily in the building construction industry), and in asbestos-cement pipes. Current usage is generally confined to chrysotile in four products: asbestos cement, friction mate-rials, roof coating and cements, and gaskets. In 1992 approximately 28 million tons of asbestos-cement products were produced in approxi-mately 100 countries (3).
