Cook, P. M., L. D. Palikar, AND D. E. Coffin. RELATIVE POTENCIES OF MINERAL FIBERS IN VIVO: FERROACTINOLITE FROM TACONITE. Presented at International Symposium on Taconite Health Hazard, St. Paul, MN, March 30-April 1, 2003.
Description:
In the early 1970s EPA provided the scientific basis for the Federal Government's lead in the Reserve Mining Case. This historic case resulted in cessation of the discharge of taconite tailings into Lake Superior and controls on air and water emissions of microscopic amphibole fibers which were shown to be similar or identical to fibers from asbestos with known human health risks. . . The carcinogenicity of ferroactinolite from taconite and its implications for other amphibole fibers associated with taconite are a major concern. These findings also are relevant to present EPA approaches to asbestos and non-traditional asbestos health problems such as vermiculite, talc, and disturbance of natural serpentine deposits.
