Silicosis - An airborne hazard

Every cubic metre of air contains millions of dust particles. Silicosis can develop when fine dust containing crystalline silica (silicid acid) is inhaled and accumulates in the lungs.

A basic component of sand, sandstone and granite, silica is ubiquitous. Only the crystalline form, however, poses a threat to human health. When inhaled, the fine dust (silicogenic dust) settles in the alveoli.
