In 1996, the International Agency for Research on Cancer (IARC) reviewed the medical data and classified crystalline silica as "carcinogenic to humans." The risk was best seen in cases with underlying silicosis, with relative risks for lung cancer of 2–4. Numerous subsequent studies have been published confirming this risk.
Clinical and toxicological research conducted on volcanic crystalline silica has found little to no evidence of its ability to cause silicosis/pneumoconiosis-like diseases and geochemical analyses have shown that there are inherent factors in the crystalline structure which may render volcanic crystalline silica much less pathogenic than some ...
Exposure to silica can cause Silicosis, which is a fibrosing interstitial lung disease caused by inhaling fine particles of silica, most commonly in the form of quartz or cristobalite. Short-term exposures of large amounts of silica or long-term (10 years or more) exposure of lower levels of silica can cause silicosis.
The grinding and sanding of synthetic engineered stone exposes workers to high levels of lung-scarring silica. Experts say the health risk should have been clear long before workers began falling ill.
A study by the Environmental Working Group found that contaminants could lead to nearly 100,000 cancer cases among people who drink it for a lifetime. Contaminated tap water could lead to 100,000 ...
Various health programs have arisen to deal with the ongoing health effects of the September 11 attacks. The World Trade Center Health Program, which provides testing and treatment to 9/11 responders and survivors, consolidated many of these after the James Zadroga 9/11 Health and Compensation Act became law in January 2011.

The increased drilling generates deadly silica dust and has caused severe forms of pneumoconiosis, better known as black lung disease, even among younger miners, some in their 30s and 40s ...
Silica: When silica is inhaled from coal ash dust, fetal lung disease or silicosis can develop. [4] Furthermore, chronic exposure of silica can cause lung cancer. [ 4 ] In addition, exposure to silica over a period of time can cause loss of appetite, poor oxygen circulation, breathing complications and fever.
