بررسی غلظت فلزات سنگین در بافت‌های مختلف جرد ایرانی به عنوان گونه‌ی شاخص زیستی دره زرشک، یزد

In this study, the concentrations of Cu, Ni, Pb, Cd, Sr and Mg in hair, lung and femur tissues of Persian Jird as bioindicator species in different regions of Darreh Zereshk copper mine were investigated. In summer of 2012, a systematic random sampling was performed by using snap trap in different parts of the copper mine. Wet digestion method and ICP-OES instrument were applied for measurement of metal concentrations in different tissues. The concentrationS of Cd and Pb were reported below the detection limit of instrument. Results indicated that Ni and Cu in hair tissue and Mg and Sr in femur tissue of Persian Jird accumulate significantly more than in other tissues (PSr>Cr>Cu>Ni in different tissues. Generally, the female of Persian Jirds accumulate more heavy metals than males. The concentration of Cu in hair tissue of the first three regions and the concentration of Ni, Sr and Cr in the fourth region showed a significant difference compared with other regions.
