Abstract
In this study concentrations of zinc chromium cadmium and lead were determined in water and three species of fish sampled from 10 selected stations along Gorgan coast using atomic absorption spectrophotometery summer 2009 Mean lead levels in water and fish samples 11950 ± 2224 μg/L and 11380 ± 3311 μg/kg were significantly higher than that of cadmium and chromium p 005 Cyprinus carpio had highest metals content than Mugila auratus and Rutilus frisikutum The evaluated metals values in water collected from Gomishan wetland Pb Cd Cr and Zn values are 14531 ± 3532 12046 ± 1144 9647 ± 605 and 8202 ± 3437 μg/L respectively were higher than the other sampling sites The result is consistent with the findings accessed by evaluation of the metals in fish specimens The metals concentrations in the fish and water samples were below the recommended limits But elevating levels of metals in water and fish made a serious concern about ecosystem and food chain contamination
