Crystalline silica is a common mineral found in the earth's crust. Materials like sand, stone, concrete, and mortar contain crystalline silica. It is also used to make products such as glass, pottery, ceramics, bricks, and artificial stone. Respirable crystalline silica – very small particles at least 100 times smaller than ordinary sand you ...

Aliabadi et al. investigated the effect of LEV on workers' exposure to silica dust in the crushing plants in Hamedan Province. Their findings indicate the extraordinary performance of LEV in reducing the exposure of workers to silica dust, so much that the concentrations of respirable particles was below the occupational exposure limits and ...
