Combining literature research and meta-analysis, the environmental hazards posed by mine dust are presented. • The health hazards of mine dust pollution are presented, to remind residents, miners and researchers to protect themselves.
اقرأ المزيدIn China, a growing number of small-scale mining enterprises are inflicting severe pollution damage to the environment, largely due to the application of obsolete technology and inefficiency of mining operations (Zhong, 1997). Small-scale mining in China is a significant source of mercury emissions.
اقرأ المزيدAir-mercury concentrations prove to be quite similar to control areas, but can reach very high levels in the vicinity of Au-Hg reburning locations, as well as in fish and human hair from the gold mining area along the Madeira River, SW Amazon. New results from an extensive survey on the mercury concentration in different environmental compartments …
اقرأ المزيدJ-WAFS researchers Scott Odell, a visiting researcher in MIT's Environmental Solutions Initiative, and John Fernández, a professor in MIT's Department of Architecture, are examining climate change, copper mining, and desalination, and their environmental and social impacts on Indigenous communities, glaciers, and agriculture …
اقرأ المزيدMine drainage is metal-rich water formed from a chemical reaction between water and rocks containing sulfur-bearing minerals. Problems that can be associated with mine drainage include contaminated drinking water, disrupted growth and reproduction of aquatic plants and animals, and the corroding effects of the acid on parts of …
اقرأ المزيدNoise pollution is quite evident while discussing about coal mining and pollution. As mining activity is taking place throughout the day, the noise coming out at the time of blasting, drilling, and transportation is polluting the entire environment.
اقرأ المزيدSources of air pollution due to coal miningThe emphasis of large-scale mechanisation of surface mining has resulted in widespread concern about deterioration of environmental quality, especially the increase in concentration of suspended particulate matter (SPM) within and around the mining site.
اقرأ المزيدNew report urges global action on mining pollution. On 5 November 2015, a waste dam at an iron-ore mine in southeastern Brazil collapsed, unleashing a tide of slurry that killed 19 people, displaced hundreds more and polluted 650 kilometres of fertile valleys and estuaries before spewing into the ocean.
اقرأ المزيدIn conclusion, the current study documents substantial air pollution emissions from coal mines in Australia, as well as higher levels of particulate matter measured in community air monitoring stations in mining versus nonmining communities. Emissions and subsequent exposures likely have impacts on the health of surrounding …
اقرأ المزيدChromium pollution due to chromite mining. The Indian mining industry is an important economic activity that contributes significantly to strengthening the national economy. Around 90% of India's chromite resource reserves are concentrated in the Sukinda Valley of Anka chromite, applying magnetic separation.
اقرأ المزيد"Mining companies and government need to do a better job of consulting with communities. We need solid plans and financing for mine closures in place from the beginning of mining operations, so that when the mine dries up, there's the money needed to secure tailings dams and protect the communities who will be there forever," Odell …
اقرأ المزيدA further environmental impact of cobalt mining in Congo is the hazy air surrounding the mines, full of dust and grit, and toxic to breathe. Studies have shown that the risk of birth defects, such as limb abnormalities and spina bifida, greatly increased when a parent worked in a cobalt mine, linked to high levels of toxic pollution caused by ...
اقرأ المزيدGroundwater pollution due to acid mine drainage (AMD) and seepage flowing from disposed mine waste are the most common water pollution arising from mining (Likus-Cies′lik et al., 2017; Sracek et al., 2010). AMD is often produced when there is an exposure of sulfide-bearing rocks to oxygen and water.
اقرأ المزيدMining also causes water pollution which includes metal contamination, increased sediment levels in streams, and acid mine drainage. Pollutants released from processing plants, tailing ponds, underground mines, waste-disposal areas, active or abandoned surface or haulage roads, etc., act as the top sources of water pollution.
اقرأ المزيدIn abandoned open-pit coal mines, surface water and groundwater form acidic waters with high concentrations of metal ions due to chemical interactions with ores such as pyrite, and the formation of acid mine drainage (AMD) is one of the major sources of pollution of world concern. For this reason, this paper reviews the formation …
