abstractbackground and objectives: considering progressive growth of industry and technology, the accumulation of environmental contaminants, especially heavy metals (hms) in the soil is of increasing worldwide concern about the probable soil pollution risks. the perception of pollutants spatial distribution pattern and recognition of factors which control this pattern and identification of pro...

Bioaccumulation of heavy metals including Cd, Pb, Cu and Zn in muscle, gill, liver, kidney and stomach in Acipencer persicus was studied. Fish were collected from the ‘Iranian fishery zone 1’ located between Astara and Kiyahshahr. Samples (n=25) were collected from five stations in the study area during the autumn catch season in 2001. Samples were analyzed by wet digestion with hydrogen peroxi...

background: one of the most critical problems in the field of water and food pollution is the heavy metal pollution. agricultural products are exposed to this type of contamination through wastewater; industrial activity and population pollutions are also in its area. since the plant in the affected areas can directly enter heavy metals into the food chain, so, it is important to check their le...

high concentration of heavy metals or long time exposure to low concentrations of these metals can usually decrease the hematological indices in fish. therefore the aim of this study was to indicate changes in hematology and serum chemistry of common carp (cyprinus carpio) after low cadmium concentration exposure. 60 apparently healthy common carp (mean weight of 700g) divided in two groups and...
