Mining operations are potential sources of airborne particulate metal and metalloid contaminants through both direct smelter emissions and wind erosion of mine tailings. The warmer, drier conditions predicted for the Southwestern US by climate models may make contaminated atmospheric dust and aerosols increasingly important, due to potential deleterious effects on human health and ecology. Dust...

abandoned surface mine excavations can be a major environmental, social and/or human healthproblem for the mining industry as well as for the community living nearby. this problem is exacerbated by therapidly growing population encroaching on areas of historic mined lands. the aim of this studywas to assess thesafety status of the historic nyala mine excavation with the purpose of coming up wit...

The activities of mining exploitation in Campo de Jales were performed in an uncontrolled way and gave rise to serious environmental contamination: rubbish depositories have been accumulated with no treatment or maintenance. An investigation developed around Jales Mine showed the existence of some chemical impact originated from the waste produced during mining activities. Some "black spots" fo...

The data obtained from field and geothermometric studies and also the REE composition of fluorites associated with lead mineralization at the Kamar-Mehdi mine are compatible with a structurally controlled, fissure filling, epigenetic, hydrothermal origin. Homogenization and last ice melting temperatures for primary fluid inclusions trapped in fluorite crystals indicate that the mineralizati...

this study was carried out for the purpose of investigating the issue of tailings dams as a potential source of contamination by trace elements in soils at the sidi bou othmane mine in the marrakech region, morocco. soil samples taken from depths of up to 15 cm and within a radius of 50 m from the tailings dams, were analyzed for cd, cu, pb and zn using atomic absorption spectrometry. average c...

Lead is a major cause of environmental concern for the industries like paint, pesticides, battery, mine, smelting etc. Lead can cause diseases related to kidney, liver, brain and nervous system. Various methods used for lead removal include electro-coagulation, ion exchange, membrane separation and suspended and attached growth biological techniques. In case of electro-coagulation, factors like...

The process of mining affects all the components of environment and ecology. resulting in different types of pollution problems like soil, surface and ground water pollution. Acid Mine Drainage (AMD) and mine spoil dumps may contain an elevated amount of Heavy metals. Physiological effect of heavy metal toxicity on algal species like Chlorella vulgaris, Scenedesmusbijugatus, Oscillatoriaamphibi...
