Assessment of The Respirable Dust Concentration of The Mine Tailing Area In Comparison With The Non Mining Area
Journal Title: IOSR Journal of Environmental Science, Toxicology and Food Technology (IOSR-JESTFT) - Year 2018, Vol 12, Issue 3
Abstract
Mining is one of the most hazardous of professions and gold mining is considered one of the worst environmental pollutants. Gold mining is often associated with positive economic benefits, however it may also have negative impacts on the environment and human health. Long duration of mining in KGF has been associated with dumping of mine tailings approximately 32 million tons of sand dumped into 15 dumplings over 8 Km in the mining areas of KGF. Mine wastes in the form of rock fragments and mill tailings have been stacked in huge piles and heaps in KGF, occupying about 15-20% of the lease area seen as mine tailings. Particulate matter concentration beyond the permissible limit at KGF has indicated influence of tailings on air pollution on the environment. The aim of the study is to report the assessment of the area dust exposure of people to airborne respirable dust concentration in mine tailing area in comparison with non-mine tailing area. Air samples was measured. A total of 12 dust samples were collected from the 4 mine areas based on the proximity of the mine tailing and 07 dust samples were collected from non-mining area in the month of June 2017. In the present study Respirable area dust concentration was significantly higher in mine tailing compared to non-mine tailing area. The current study shows there is a significant increase in mean area respirable dust concentration in mine tailing area compared to non-mining area
