Soil contamination with potentially toxic elements (PTEs) in agricultural lands, in part, is responsible for limiting the crop productivity and the food chain contamination. The objective of this study were to asses the limiting of crop productivity by cadmium (Cd) and lead (Pb), the potential transfer and bioaccumulation of these PTEs in plants, and ultimately the food chain contamination to e...

Models such as the Biotic Ligand Model (BLM) predict how natural organic matter (NOM) and competing ions (e.g., Ca(2+), H(+) and Na(+)) affect metal bioavailability and toxicity in aquatic organisms. However, such models focus upon individual metals, not metal mixtures. This study determined whether Pb and Cd interact at the gill of rainbow trout (Oncorhynchus mykiss) when trout were exposed to...

measurement of availability and mobility of heavy metals in river sediments is required in order to understand the behavior of these metals and to prevent potential toxic hazards. leaching column experiments were conducted for four sediment samples to determine the degree of mobility and the distribution of zn, cd, ni, cu, and pb because of an application of spiked heavy metals in sediments. se...

This study was conducted to determine Pb (Pb) and Cd (Cd) concentrations in the liver and muscle of Platycephalus indicus (flathead) in Minab, Qeshm Island and Khamir Port in the Northeastern Persian Gulf. Moreover, the influences of season (winter and summer) and target tissue (liver and muscle) on the Pb and Cd concentrations in flathead were investigated and compared with FAO/WHO standards f...

background: evaluation on the toxicity of two mainly contaminant heavy metals, cadmium (cd) and lead (pb) through the food chain was the aim of this study. methods: a total number of 270 healthy common carp (4±1.14 g) in april, 2015 transported to the khatam alanbia university of technology, behbahan, iran. fishes were divided into three groups and transferred to the 20 l aquaria each containin...
