Biota-sediment accumulation factor and concentration of heavy metals (Hg, Cd, As, Ni, Pb and Cu) in sediments and tissues of Chiton lamyi (Mollusca: Polyplacophora: Chitonidae) in Chabahar Bay, Iran
Heavy metals and some organic substances which are drained into the aquatic environments and cannot be decomposed or eliminated will sink into sediments or find their way into different levels of food chain. Bioaccumulation is the process of continuous deposition and aggregation of these substances into the body tissue of living organisms. Mollusks are remarkably appropriate to be used as bio-i...

متن کاملHeavy metal contamination in surface sediments of four important rivers leading to the Caspian Sea
Heavy metals tend to be adsorbed and accumulated in sediments as opposed to water or suspended solids. Sediments and biota bodis can act as a final sink for heavy metals in the aquatic environments. They accumulate through the food chain posing potential biological and ecological risks. Therefore, research on the heavy metal concentrations in aquatic ecosystems can help to protect human health ...
متن کاملAssessment of Heavy Metals Pollution in Water and Sediments of Djendjen River, North Eastern Algeria
Water and sediment samples have been collected from five different stations, located along Djendjen River between February and June, 2016 so that the concentrations of Cd, Ni, Zn, and Cu could be determined. The extent of the sediment pollution has been assessed, using the multiple pollution indices, namely Contamination Factor (CF), Pollution Load Index (PLI), and the geoaccumulation index (Ig...
متن کاملInvestigation of heavy metals accumulation in the sediment and body of carp fish in Aras River
Heavy metals are considered as the most dangerous water contaminants because of their possibility of bioaccumulation and toxic effects. This study tried to investigate the bio-availability of heavy metals in terms of Ni, Zn, Cu, Fe, Hg, Cd, and Pb in the sediment during dry seasons in Aras River basin located in Ardabil Province, north-west of Iran. Also the metal concentration in the skin and ...
