Abstract
The term “asbestos” refers to a family of hydrated silicates with an aspect (length to diameter) ratio of > 3:1 as defined by regulatory policy in the United States. Physicochemical characteristics vary considerably amongst the various types of asbestos. Chrysotile asbestos [Mg6Si4O10(OH)8], the most common asbestos type, accounts for most of the world’s production of asbestos. Crocidolite asbestos [Na2Fe(III)2Fe(II)3Si8O22(OH)2], an iron containing fiber, belongs to the amphibole family. It is of less industrial importance than chrysotile but is more pathogenic than chrysotile in man in the causation of malignant mesothelioma (Mossman et al., 1990a).
