Increased sediment loading comprises one of the most important and pervasive
anthropogenic impacts on aquatic ecosystems globally. In spite of this, little is known of the …

ABSTRACT A The potential ecological effects of rising levels of heavy metals concentrations
in the environment are of great concern due to their highly bioaccumulative nature …

A hydrochemical study on a 630km stretch of river Gomti, a tributary of the river Ganges
examined the distribution of heavy metals in sediments and the partitioning of their chemical …

Contamination of heavy metals, namely, lead, cadmium, zinc, nickel, copper, chromium and
mercury was evaluated in the samples of water and tissues of Labeo rohita and …

This study reports the spatio-temporal changes in water quality of Nullah Aik, tributary of the
Chenab River, Pakistan. Stream water samples were collected at seven sampling sites on …

The concentration and speciation of heavy metals (Cu, Co, Ni, Zn, Cr, Pb and Cd) were
studied in surface sediment from the Yangtze River (YR) to the East China Sea (ECS) shelf …

In this paper we explored the heavy metal bioaccumulation (Cd, Cu, Pb and Zn) in
Procambarus clarkii, a crayfish recently suggested as a potential bioindicator for metals …

Pollution of river bottom sediments with heavy metals (HMs) has emerged as a main
environmental issue related to intensive anthropopressure on the water environment. In this …

Chemical fractionation of seven heavy metals (Cd, Cr, Cu, Mn, Ni, Pb and Zn) was studied
using a modified three-step sequential procedure to assess their impacts in the sediments of …

Heavy metals are normally occurring elements that have a density at least 5 times higher
than of water. Their plentiful domestic, industrial, agricultural and technological usages have …
