soil contamination significantly reduces environmental quality and affects human health. to investigate and assess the effects of land use on the concentrations of some heavy metals in surface soils of golestan province, 227 soil samples (0-60 cm) were collected from three types of land uses including agricultural lands, natural, and industrial areas. the total metals and metalloids (cr, se, as...

This study used hair and nails to biomonitor heavy metals (Pb, Cd, Cr and Cu) from geological source and exposure through regular fish consumption among children in Lake Victoria, Kenya. Concentration of Pb and Cu in water reflected anthropogenic pathways, while Cd and Cr reflected accumulation from the catchment basin. Higher concentration of heavy metals in the nails samples than the hair sam...

The objective of the present study is to determine the bioaccumulation of heavy metals in various organs of the fresh water fish exposed to heavy metal contaminated water system. The experimental fish was exposed to Cr, Ni, Cd and Pb at sublethal concentrations for periods of 32 days. The elements Cd, Pb, Ni and Cr were assayed using Shimadzu AA 6200 atomic absorption spectrophotometry and the ...

A survey was conducted to monitor the influence of city sewage irrigation on the heavy metal build up in soils around Bhopal. Concentration of the heavy metals in effluent was within safe limits. Diethylene triamine penta acetic acid extractable Pb, Cd, Ni, Co, Cr, Fe, Mn, Zn and Cu in the sewage irrigated surface soil ranged 3.5-6.8, 0.15-0.40, 2.56-5.58, 1.59-3.89, 0.45-0.55, 3.5-15.8, 3.6-8....

to understand the present status of metal contamination along the haiphong-halong coast, the concentrations of as, cd, cr, cu, pb, and zn were seasonally determined in rock oysters from four sites during 2013. the results indicated that a high concentration of heavy metals was found in oysters. the average concentrations of zn and cu were extremely high, ranging from 823.6–3201.6 and 238.1–1597...
