Abstract

Background and Objective: We investigated the accumulation of four toxic Heavy metals (Pb, Cd, Hg, and as) in the muscle, skin, and gill tissues of three fish species (Alectis indicus; Epinephelus chlorostima, and Lutjanus imniscatus), and the relationships between weight and total standard lengths and the levels of the Heavy metals as well as assessing the inter-metal relationships. Method: The samples were collected from two important Bushehr fishery zones located in the Iranian part of the Persian Gulf during September– October 2013. The muscle, skin, and gill tissues were separated after the biometric measurements. The metals were extracted from tissues using the closed digestion method and an acidic mixture. The heavy metal concentrations were measured using a sequential atomic absorption spectrometer. Findings: A negative linear relationship was detected between the accumulations of Pb, Cd, and Hg and standard length and a positive linear relationship was observed between the accumulation of the total length and weight. The gills had significantly higher heavy metal concentrations than those in the other tissues whereas muscle had significantly lower concentrations of the metals compared to those in the other tissues. The highest Pb and Cd concentrations were detected in Alectis indicus, the highest Hg and as concentrations were found in Lutjanus imniscatus, and the lowest concentrations were found in Epinephelus chlorostima. Discussion and Conclusion: In all cases, the quantities of toxic Heavy metals (Pb, Cd, Hg, and As) were higher than the concentrations recommended in the FDA, WHO, and NHMRC international guidelines for human consumption.
