Federal Fix for Silica Dust Understates What We Found:
It plagues thousands of sick and dying coal miners like him. The likely cause, studies conclude, is exposure to clouds of silica dust while mining coal, and digging through solid rock to get to coal seams and prepare them for mining. Silica, one of the most abundant minerals on earth, is 20 times more toxic than coal dust alone.A representative sample of gold mine wastes of sandy grain size was used in making the glass.

Country-specific carbon footprint and cumulative energy demand
Illegal silica sand mining is happening in more than 70 countries (Rege and Lavorgna, 2017). Countries such as China, India, and Singapore with high growth rates need a large amount of silica sand to expand their high-tech industries (Ioannidou et al., 2020). This demand has increased silica sand price, making illegal trades more attractive.Inhalation of silica dust by human being during hand drilling in mica mining, lead & zinc mining, silica refractory manufacture and in foundaries causes a) Asphyxiation (suffocation) b) Shortness of breath c) Tuberculosis d) All of the above.

Reducing disease and death from Artisanal and Small-Scale Mining
Artisanal and small-scale mining (ASM) takes place under extreme conditions with a lack of occupational health and safety. As the demand for metals is increasing due in part to their extensive use in ‘green technologies’ for climate change mitigation, the negative environmental and occupational consequences of mining information was available for 881 deaths. Metal/nonmetal mining was the industry recorded for over 15% of these 881 deaths, with mining machine operator the most frequently recorded occupation. In light of ongoing silica overexposures and reported silicosis deaths in metal/nonmetal miners, an ongoing threat to miners’ health is evident.Best Practices for Dust Control in Metal/Nonmetal Mining

CDC Mining FAST Field Analysis of Silica Tool NIOSH
This enhances the ability to collect data more effectively, enables better control over potential exposures, and protects worker health. The FAST (Field Analysis of Silica Tool) software processes raw Fourier transform infrared (FTIR) data from field-based instruments and calculates an RCS mass and concentration estimate for each sample.Considering production or extraction of silica, in the proposed LCA, silica sand showed low burdens per sand kg, related to its extraction.

CDC Mining Mining Program Strategic Plan, 2019-2023
These relationships ensure that the NIOSH Mining Program focuses taxpayer dollars on solving the highest priority mine worker health and safety challenges. In order to inform our stakeholders and the public about our current and future plans, we have written an updated five-year Strategic Plan (2019–2023).Introduction. Human exposure to respirable crystalline silica (RCS), primarily quartz dust, occurs in a variety of industrial and occupational settings including: quarry and mining, mineral processing, foundry, construction, ceramic, and brick and tile industries. 1 The International Agency for Research on Cancer classified crystalline silicas (including Evaluation of workplace exposure to respirable crystalline silica in

Environmental Health and Safety Hazards of Indigenous Small
Small-scale gold mining (SSGM) refers to mining by individuals, groups, families, or cooperatives with minimal or no mechanization, often in the informal (illegal) sector of the economy. In the Philippines, the gross production value of small-scale gold mining is 1.0 billion pesos (USD 21.7M) as of 2014. 1The scale of a profound human tragedy. Concern over silica's role in black lung has been growing for decades, and mine safety advocates have urged regulators to act since 1974. If the samples show excessive silica, mining companies will be required to reduce the exposure, using what are called engineering controls:As coal miners suffer and die from severe black lung, a proposed

A Brief Review of Silicosis in the United States PMC
Abstract. Silicosis may be defined as the disease resulting from chronic occupational exposure to silica dust. Silica is primarily composed of quartz dust and has been classified since 2000 as a known human carcinogen by the U.S. government. Silicosis may lead to impairment of lung function resulting from fibrosis of the lungs.Silica mineral is the major constituent of Lithosphere and its manifold industrial use makes it more valuable. But, its fast extraction damages the environmental quality of a region. In this paper the pros and cons of silica mining by the environmental perspective has been measured by taking Shankargarh region as a case.Impact of silica mining on environment Academic Journals
