Fiber Dimensions of Crocidolites from Western Australia, Boliva, and the Cape and Transvaal Provinces of South Africa.
MISSING :33 pages
The Bureau of Mines measured fiber dimensions on crocidolites (riebeckite-asbestos and magnesioriebeckite-asbestos) from the world's four crocidolite mining regions. The objective of the study was to determine whether there are measurable morphological differences between crocidolite fibers that correlate with the high reported incidence of mesothelioma in miners and mill employees in the Cape Province of South Africa and Western Australia, as compared with little or no reported incidence of this cancer in the transvaal province of South Africa or Bolivia. Fiber dimensions measured with the scanning transmission electron microscope showed that crocidolites from Western Australia and the Cape Province have more thin fibers than crocidolites from Bolivia and the transvaal province.
