The common practice of remediating metal contaminated mine soils with compost can reduce metal mobility and promote revegetation, but the effect of introduced or colonising earthworms on metal solubility is largely unknown. We amended soils from an As/Cu (1150 mg As kg(-1) and 362 mg Cu kg(-1)) and Pb/Zn mine (4550 mg Pb kg(-1) and 908 mg Zn kg(-1)) with 0, 5, 10, 15 and 20% compost and then in...

Lygeum spartum is a native species in semiarid Mediterranean areas that grows spontaneously on acid mine tailings. We aimed to study the suitability of this plant for phytostabilization. L. spartum was grown from both seeds and rhizomes in acid mine tailings with various fertilizer and lime treatments. Untreated soils had a solution pH of 2.9 with high concentrations of dissolved salts (Electri...

soil contamination in the vicinity of the abandoned lakan lead and zinc mine was studied. the results showed that over the past decades, the environmental pollution was caused by lead, zinc tailings dam and acid mine drainage. the average of lead, zinc, cadmium, copper and nickel is 1295, 4273, 27, 185 and 92 mg/kg, respectively in the soils of tailings dam. these metals were continuously dispe...

heavy metal concentration in the soils and sediments has increased worldwide during the last century due to the mining, smelting, and industrial activities. the forumad chromite deposit is located in the sabzevar ophiolitic complex (soc), with a long history of mining activities, yet very little is known about the heavy metal contamination in its surrounding environment. in this research work, ...

Five medicinal plants viz. Abelmoschatus moschatus Linn., Clitoria tematea L., Plumbagozeylanica L., Psorolea corylifolia L. and Withania sominifera L. were grown in a polypot experiment in five soils representing coal mine soil, coppermine soil, fly ash, skeletal soil and forest soil with and without mycorrhizal inoculations in a completely randomized block design. Dry matter yield and mycorrh...

This research focuses on the heavy metal contamination of the paddy soils and rice from Kocani Field (eastern Macedonia) resulting from irrigation by riverine water impacted by past and present base-metal mining activities and acid mine drainage. Very high concentrations of As, Cd, Cu, Pb and Zn were found in the paddy soils (47.6, 6.4, 99, 983 and 1,245 microg g(-1)) and the rice (0.53, 0.31, ...

Rare earth mine tailing dumps are environmental hazards because tailing easily leaches and erodes by water and wind. To assess the influence of mine tailing on the geochemical behavior of rare earth elements (REEs) in soil, sixty-seven surface soil samples and three soil profile samples were collected from different locations near China's largest rare earth mine tailing. The total concentration...

Heavy metal pollution in soils caused by mining and smelting has attracted worldwide attention for its potential health risks to residents. This paper studies the concentrations and accumulations of Sb and As in both soils and vegetables and the human health risks of Sb and As in vegetables from Xikuangshan (XKS) Sb mine, Hunan, China. Results showed that the soils were severely polluted by Sb ...

The core microbiota of a neutral mine drainage and the surrounding high heavy metal content soil at a Brazilian copper mine were characterized by 16S rDNA pyrosequencing. The core microbiota of the drainage was dominated by the generalist genus Meiothermus. The soil samples contained a more heterogeneous bacterial community, with the presence of both generalist and specialist bacteria. Both env...

the aim of the study is to determine the major source and extent of metal pollution in the vicinity of dashkasan gold mine. dashkasan mine has resulted in extensive contamination of soils by arsenic (as) and potentially toxic ore-related elements including mercury (hg), antimony (sb) and cadmium (cd). soils samples were collected and analyzed for as, cd, hg, pb and sb. the concentration of each...
