Silica Sand Carcinogens

Background: Aims of our study were to explore whether and to what extent exposure to other lung carcinogens, or staging and clinical features of silicosis modify or confound the association between silica and lung cancer. Methods: We used data from a nested case-control study, conducted in the late 1980s in 29 Chinese mines and potteries (10 tungsten mines, 6 copper and iron mines, 4 tin mines ...

    Sand, perlite, grog, and vermiculite contain free silica and are, therefore, highly toxic by inhalation. Vermiculite is also frequently contaminated with asbestos. There is a danger of accidents if clay or water can be added while the mixer is in operation. Bags of clay and glaze materials can be very heavy, and lifting can cause back problems.
