چکیده مقاله:
Intensified industrialization and human activities have resulted in the release of various contaminants into the environment. Among them, heavy metals are often present as a result of mining, milling and agriculture industrial. In the present investigation, concentrations Cd, Pb and Zn in Dez River (Iran) bed sediments and water around the Agricultural land were measured from several sample locations. Significant variations in metal values were evaluated using One-Way analysis of variance (ANOVA) followed by Duncan post hoc test p<0.05. Concentration of studied metals in both water and sediment are measured by using atomic absorption spectrometer. In sediment high levels of Cd, Pb and Zn were measured in Hamid Abad Forest (0.18, 6.1 and 10.1 mg kg-1 dw). In water and sediment, levels of heavy metal for Cd, Pb and Zn in the present study were lower than International Standards for these metals as declare by the World Health Organization (WHO).
