Crystalline silica has been classified as a human lung carcinogen, and can cause serious lung disease and lung cancer. It only takes a very small amount of respirable silica dust to create a health hazard. One of the dangerous effects of silica exposure is a disease called silicosis, which can be contracted after just a few months of high exposure.
