Abstract :

Abstract[1] We assessed and compared the concentration of heavy metals Mn, Zn, Fe and Cu in the muscle, liver and gill tissues of Liza abu in the Karkheh River in Khoozestan Province in winter 2009. Muscle tissue, liver and gills of 36 specimens were separated after bioassay. The study measured metal concentrations by wet Digestion Method using Atomic Absorption Spectrophotometry Perkin Elmer4100 in the laboratory of Alborz project in Shahrekord. This study showed that the average concentration of heavy metal in muscle tissue was the highest and in gill tissue the lowest. Iron concentration was more than zinc, manganese and copper in different organs of Liza abu (P≤0.05). Among metallic Iron accumulation in muscle tissue, liver and gills there was a positive linear relationship (P≤0.05). Manganese and copper in muscle and liver had no significant differences. However, there was a significant difference between muscle and liver with gill (P≤0.05). Zinc in the liver, gill and muscle had no significant difference (P≥0.05). The results of heavy metals in fish muscle and its comparison with standards Liza abu, UK (MAFF), WHO, FDA, NHMRC and NFA puppet showed manganese and iron metal contamination compared to WHO and FDA standards is. *Corresponding Authors; Email: [e-mail]
