Study and comparison of Hg, Cd and Pb accumulation in the muscle and liver tissues of Aspius vorax in Karoon River,in winter season

The heavy metals are kind of the pollutants which created too much problems in aquatic ecosystems for both aquatics and human. A comparative study was conducted on concentration of heavy metals Hg, Cd and Pb in the muscle and liver tissues of Aspius vorax of Karoon River in winter 2011. Eighteen samples were taken in station one (Ahwaz six Bridge). Metals were extracted from the tissues using wet Digestion method and concentration of the heavy metals was measured by Atomic Absorption Spectrophotometer Perkin Elmer 4100. Data were analyzed with SPSS17 software in terms of one-way (ANOVA) test. The highest concentration of Hg, Cd, and Pb was 21.50±0.85, 127.73±2.27 and 238.26±7.51µg/Kg/wd, respectively. Accumulation of Hg, Cd and Pb in the muscle and liver of Aspius vorax were significant different (P<0.05). In this study, compare to WHO and FDA standards, concentration of Hg, Cd and Pb was lower.
