Powder on the Face
Most of the talc produced before 1972, Cutis (37:328) reports, was contaminated with some asbestos, which is not surprising since both of these substances are crystalline forms of magnesium silicate and often found side by side in the same mine.

Talc miners, like asbestos miners, have a higher than normal share of health problems, often develop scarring of the lungs, and have a three to four times normal incidence of lung cancer. Exposure to asbestos dust in the workplace often results in tumors in the chest and lungs as many as 20-30 years later.
