Evaluation of concentration of some heavy metals in different tissues of common mouse (Rattus norvegicus) as a bio-indicator species in Aran and Bidgol city (Isfahan Province)

One of the most important environmental pollutants is heavy metals that have accumulated in the tissues of organisms and at low levels can cause poisoning. The present study aims to measuring the concentration of heavy metals in different tissues of Common Mouse as a bioindicator species in Aran and Bidgol city. Thirteen specimens of Common Mouse were collected from two agricultural area of Majidabad and Beheshtieh located in Aran and Bidgol in summer 2013. Concentrations of metals in tissues of this species were measured by ICP-OES. Mean concentration of metals in liver, kidney and muscle was obtained respectively for Zinc 135.06, 87.97 and 61.80 µg/g dw, for copper was 21.59, 18.56 and 7.33 µg/g dw, for lead was 4.26, 6.80 and 2.39 µg/g dw, and for cadmium was 4.19, 7.25 and 4.97 µg/g dw. The results of one-way analysis of variance showed that accumulation of zinc in liver and lead in kidney were significantly higher than other tissues (p
