Exposure was highest before asbestos regulations were implemented in the 1970s, but active vermiculite, talc and taconite mines in the U.S. remain contaminated with asbestos and pose an exposure threat to current miners. Coal miners have also developed asbestos-related diseases, and this is likely caused by asbestos products used in coal mining.
