Soil erosion in the Pisha sandstone area of the Loess Plateau in China has become a severe environment issue that has raised concerns globally. The projects of ecological restoration in this area and their impact on soil erosion have been analyzed using the unmanned aerial vehicle remote sensing system (UAVRSS) and the revised universal soil loss equation (RUSLE) in the Two-Tiger Valley Basin in 2013...
Heavy metals pollution of surface soils is a major global issue. To assess the ecological risk caused by heavy metals, 280 samples were collected in Chiping, Shandong Province, China. Eight different heavy metals in surface soils (Cu, Pb, Cd, Cr, Hg, Ni, Zn, and As) were analyzed in this study. The author got the realization of the eight kinds of heavy metals respectively based on sequential simulation...
As scattered elements, thallium (Tl) contamination poses a significant threat to human health due its high toxicity. Sulfate-reducing bacteria (SRB) embedded in PVA-sodium alginate matrix was utilized as a novel bio-remover to remove Tl from aqueous solution. The effect of pH, temperature, and initial Tl concentration on removal capacity of immobilized beads were studied and discussed in this work...
Corporate environmental information disclosures (EIDs) are important policy tools for environmental protection. This paper assesses and longitudinally examines EID changes in Chinese listed nonferrous metal companies from 2008 to 2012 through their annual, social responsibility, environmental, and sustainability reports. Using content analysis and multivariate regression methods, we fi nd a signifi...
Perfluorooctanoic acid (PFOA) has been found to distribute and accumulate widely in the environment. In this study, the acute toxicity, behavioral activity, regeneration, antioxidant enzyme activities, and cell apoptosis effects of PFOA on planarian Dugesia japonica have been investigated. The results show that the mortality is directly proportional to the PFOA concentration, and planarian locomotor...
