De gevaren van amosiet asbest in Zuid Afrika

15-02-2008 00:00

Amosiet asbest veroorzaakt zowel niet-kwaadaardige als kwaadaardige asbestziekten. Het is echter minder schadelijk dan het blauwe crocidoliet asbest. In Zuid Afrika zijn de meeste mijnwerkers zowel aan amosiet- als aan crocidoliet-asbest blootgesteld. Bron: Murray, J. &. Nelson, G., (2007).

This study focuses on the amosite mining region in South Africa and associated health effects, compared to other mined asbestos fiber types. Historically, dust and fiber levels were high in the amosite mills and mines, and many miners and members of the surrounding communities were exposed to the fibers. Research has shown that amosite produces both benign and malignant disease. Nevertheless, the mesotheliomagenic potential of amosite is several fold lower than crocidolite. The risk of disease associated with amosite exposure is difficult to quantify. Reasons for this include the scarcity of available information, including fiber measurements, and case ascertainment, as well as the juxtaposition of the amosite and crocidolite asbestos seams in South Africa.
