Title

Survey on heavy metals of Hg, Cu and Zn in muscle and liver tissues of Rainbow trout (Oncorhynchus mykiss) in various water resources of West Azarbayejan province

Pages

  75-88

Abstract

 In this study, the amount of Heavy Metals Hg, Cu and Zn in Muscle and Liver of Rainbow trout were compared in farms were compared in three sources of water well, spring and river in west Azarbaijan province. After supplying 20 fish samples from each water source (weight: 220g) Heavy Metals of the tissues were measured using Cold-Vapor technique and atomic absorption flame spectrometry. The results indicated significant relationship between tissues, water source and fish sex with the metals accumulation. The highest amounts of Hg (0. 73± 0. 18 mg/kg) and Zn (101. 2± 18. 6 mg/kg) observed in Liver of fish in river water source, and the highest amount of Cu (88. 84± 34. 22 mg/kg) was observed in Liver of fish in well water source. Regardless of the source of water, comparison of amount of Heavy Metals in tissues of both sex showed that accumulated metals in female tissues was significantly (p˂ 0. 05) more than that of male. There wasn’ t significant linear-regression between metals accumulation and fish biometric indices. The amount of Hg in Muscle of fish in water sources was lower than standards (EPA, FAO, WHO, UK MAFF, FDA, NHMRC), and amount of Cu and Zn of Muscle in water sources was less than EPA and FAO standards respectively, and was more than other standards. According to the results, spring is the best water source, and it is essential to continuously monitor the water and farmed fish pollution in river's water source to maintain the health of fish consumers.
