Air monitoring for silica dust. The mandatory limit for silica dust exposure in Australia is /m 3 averaged over an eighthour day (except in Tasmania where it is /m 3), although the American Conference of Governmental Industrial Hygienists (ACGIH) have recommended this be limited to mg/m 3.. However, there is no evidence to support a safe level of silica dust exposure.

The chemistry of silica and its potential health benefits

Chemically, silica is an oxide of silicon, viz., silicon dioxide, and is generally colorless to white and insoluble in water. When associated with metals or minerals the family of silies is formed. There are several water soluble forms of silica referred collectively to as silicic acid (ortho, meta, di, and trisilies), which are present in surface and well water in the range of 1100 ...
