two core sediments (C1 and C2) of Xiangjiang River, Chang-Zhu-Tan region, Hunan Province, China. The heavy metal contents are relatively higher, especially for the surface or near the surface layers..., and 84.67 in C1 and C2, respectively. The correlation of heavy metals with sulphur indicates that they are precipitated as metal sulphides. Correlation matrix shows significant association between heavy......
Electrochemical Sensing of Heavy Metal Ions based on Monodisperse Single-crystal Fe3O4 Microspheres燕昊伟,胡双启School of Environment and Safety Engineering, North University of China摘 要:Single-crystal Fe3 O4 with monodisperse microspheres structure has been used for individual electrochemical detection of heavy metal ions. Morphology and structure......
’ health through food strains. Obviously, these metals’ potential ecological harm had been coming down to observed harm to the ecology. Key words: gold mining activity; soil pollution; heavy metal... physicochemical properties, namely pH and mechanical composition were also measured. The data and heavy metal concentrations have been discussed elsewhere[17]. Soil heavy metal concentrations were analyzed......
Synthesis and Heavy Metal Immobilization Behaviors of Fly Ash based Gepolymer张云升Jiangsu Civil Engineering Materials Key laboratory,Southeast University摘 要:heavy metal ions, and the immobilization efficiency reached 90% greater when heavy metals were incorporated in the fly ash geopolymer in the range......
Role of Heavy Metal Ions in the Formation of Oxyfluoride Glasses and Glass CeramicsMin Liu1,Lijuan Zhao1,2,Yan Liu1,Zijian Lan1,Lifen Chang1,Yiming Li1,Hua Yu11. The MOE Key Laboratory of Weak Light... of different heavy metal ions on the formation of the oxyfluoride glasses and glass ceramics, samples with different Pb F2/Cd F2 ratios have been prepared by the melting quenching and thermal treatment......
Removal of SO42-, uranium and other heavy metal ions from simulated solution by sulfate reducing bacteria WANG Qing-liang(王清良)1, 2, DING De-xin(丁德馨)2, HU E-ming(胡鄂明)2, YU RUN-lan... geochemical environment for groundwater is changed since leachant is injected into the water bearing uranium deposit. This increases the concentration of SO42-, uranium and other heavy metal ions......
Extraction and separation of Fe(Ⅲ) from heavy metal wastewater using P204 solvent impregnated resinQi Sun,Li-Mei Yang,Li Zhang,Song-Tao Huang,Zheng XuNational Engineering Laboratory of Biohydrometallurgy,General Research Institute for Nonferrous Metals摘 要:The extraction and separation of Fe(Ⅲ) from heavy metal wastewater generated in zinc smelting......

The results show that heavy metal content in soil significantly differs... identify health risks. Key words: soil; heavy metal; health risk; land use; geographic information system (GIS) 1 Introduction With the rapid development of industry, heavy metal pollution in soil has......
to evaluate the comprehensive pollution of heavy metals. The results show that the vertical distributions of heavy metals are different. The heavy metal concentration in the reclamation soil is lower but it is still higher than the soil background value. The heavy metal concentration in the interface between the soil and tailings is the highest, the pollution degree is the strongest. The pollution......
