Asbestos mining and milling have well characterised relations with a number of hazards for the respiratory system, 4– 9, 20– 23 and it is intuitive to consider that reduction in exposure would be related to less morbidity. However, few studies have examined the effects of changing workplace conditions on the respiratory health of a large ...
There are currently no functioning asbestos mines in the United States, but Canada and many other countries continue asbestos mining in order to sell the substance to manufacturers throughout the world. Mining and milling activities to remove asbestos from underground rock exposes workers to dangerous levels of the carcinogen.
NIOSH studied the health effects of mining and milling talc. The study included 710 men who mined or milled talc. The study included all men who had worked for at least 1 day between 1947 and 1978. The purpose of the study was to see if exposures at this work site were associated with lung disease, including cancer.
