The heavy metals concentrations including Zinc, Copper, Lead and Cadmium (Zn, Cu, Pb and Cd) in water and sediments in Gorgan Bay and their accumulation in Rutilus frisii kutum, Acipenser persicus, Rutilus rutilus caspicus and Cyprinus carpio organs (gills, muscle, kidney and liver) were investigated. There was substantial increase in concentration of heavy m...

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...

This study aimed to evaluate the concentration of heavy metals in liquid effluents and to quantify the mercury content in dental amalgam waste generated by dental clinics. Three neighbouring cities in Northeast Algeria were considered in this study (Constantine, Skikda, and Annaba). Heavy metals, such as Hg, Cu, Zn, Fe, Ni, Mn, Cr, Cd, and Pb, were analysed in wastewater and then compared with ...

industrial activities lead to an increase in heavy metal burden in rivers. sediment and algae (spirogyra sp.) samples were collected from the shoor river to investigate their heavy metal concentrations. dry and ashed samples of algae and sediment were digested using concentrated nitric acid. heavy metals (as, fe, zn and cr) concentration measured using an icp-oes instrument (perkinelmer, usa). ...

abstract heavy metals uptake and their distribution in plants are different. in addition to the genetic factors, environmental factors such as interactions of heavy metals with essential elements are very important on the amount of heavy metals uptake. in this study, the effects of iron and manganese on accumulation of cadmium in shoot and root of sunflower and corn in different concentration o...

ría and coastal zone are, in particular, vulnerable to heavy metals pollution. concentrations of 10 metals in liver, muscle and kidney of the sole (solea vulgaris) from ría of vigo and its coastal zone (spain) were measured from april 2006 to february 2007 and the relationships between fish size age and metal concentrations in the tissues was investigated. concentrations of the heavy metals in...

The aim of this study is to analysis the performance of Robinia pseudoascacia (black locust tree) to accumulation some of heavy metals and compared with the concentration of these metals in falling dust Yazd highway green belt. In order to an experiment was conducted as factorial based on completely randomized design with four replications.The results showed that the concentration of, ...
