The aim of this study was to determining metals concentration in water, sediment samples and two organs of Common coot (liver and kidney). Materials and methods: This study was tested on water, sediment and 30 Common coot samples, in winter 2009. The water and sediment samples were respectively collected by Rotner bottle and Ekman grab within six sites of Gomishan and Khalij Gorgan wetland. The concentration of heavy metals in samples (Bird tissues, water and sediment) was measured by GF-AAS and Flame-AAS. Results: The data indicated that maximum heavy metals concentration in water belongs to lead (0.154 ± 0.02 ppm) and in sediment to Zn (2.04 ± 0.42 ppm). There was a significantly high correlation among heavy metals in water and sediment samples (P LA eng UL http://jmums.mazums.ac.ir/article-1-963-en.html M3 ER -
