11/05/2015#0183;#32;Silica sand mining has minimal environmental impact, involves virtually no public health risk, and is an important part of domestic energy production that has substantial economic benefits. Heartland Policy Study No. 137, Environmental Impacts of Industrial Silica Sand (Frac Sand) Mining, documents the following facts:
05/02/2019#0183;#32;Satellite images from 1995 and 2013 show the impact of sand mining on the waterway connecting China''s Poyang Lake and the Yangtze River. NASA Earth Observatory By removing so much sand, the miners have almost doubled the waterways capacity, partially draining the lake and making it more vulnerable to drought .
The chronic silicosis caused by silica exposure poses unique dangers for employees working at frac sand mining sites. Because longterm exposure can be fatal, the Labor Departments Occupational Safety and Health Administration (OSHA) issued draft regulations designed to reduce the health risk and previously issued a hazard alert .
13/03/2019#0183;#32;The onset of disease may occur long after the exposure has stopped. Silicosis, lung cancer, chronic bronchitis, and several autoimmune diseases have been linked to long term or very high exposures to crystalline silica. At High Concentrations in the Air. Health effects of crystalline silica have been well studied in workers.
Environmental Impacts of Industrial Silica Sand (Frac Sand. Environmental Impacts of Industrial Silica Sand (Frac Sand) Mining study will be dedicated to addressing the many misleading claims made about industrial sand mining in various environmental reports in an effort to develop better tools for policymakers on the subject matter.
Silica (Frac) Sand Mining Minnesota Legislature. Silica sand mining has been a divisive topic in Southern Minnesota. Advoes claimed the industry would bring jobs and economic development to the regions involved. Environmentalists and public health experts urged caution due to concerns over potential negative impacts of the fine silica sand dust
28/09/2010#0183;#32; Silica more toxic than coal and is regulated to 1/20 th the level of coal dust Freshly fractured silica more toxic than aged silica Smaller particles are more problematic Consequences of overexposure: Silicosis Airways diseases Pulmonary tuberculosis Chronic renal disease
