Heavy metals in Acanthopagrus arabicus Iwatsuki, 2013 from Karachi Coasts, Pakistan and potential risk of human health

Abstract

During the present concentrations of heavy metals (Fe, Mn, Zn, Pb and Cd) were estimated in muscle and liver tissues of commercially important marine fish Arabian yellowfin seabream (Acanthopagrus arabicus Iwatsuki, 2013) collected from Karachi Fish harbour during January-October, 2015. The results showed that muscle had the lowest metal concentrations as compared to liver tissues. The Fe concentration was the highest for both in muscle as well as for liver among the other heavy metals. The ranges of Fe concentration were found from 20.16 to 63.52 and 20.16 to 641.52 mg/kg in muscle and liver, respectively. The lowest metal concertation was Pb which was followed by Cd. Pb and Cd concentrations in the muscles of A. arabicus ranged from 0.01 to 0.52 and 0.23 to 0.88 mg/kg, respectively; whereas Pb and Cd concentrations in the liver of Arabian yellowfin seabream ranged from 0.01 to 2.58 and 0.23 to 2.64 mg/kg, respectively.
