Abstract：The contents and distribution of heavy metals As ,Hg ,Cd ,Pb ,Cu and Zn in visceral mass , gill ,muscle ,shell and pereiopods were investigated and evaluated in ridgetail white prawn Exopalaemon carinicauda cultured in a pond in Southern Jiangsu province using atomic absorption and atomic fluorescence .The results showed that heavy metal contents were found significantly higher in visceral mass and gill than those in the muscle ,shell and pereiopods ,from 0 .0190 mg/kg (Hg ) to 20 .9 mg/kg (Cu) in visceral mass ,and from 0 .00636 mg/kg (Hg) to 26 .4 mg/kg (Zn) in the gill .Zn and Cu contents were relatively higher and the Hg contents were the minimum in the 5 tissues .Since the muscle was found to account for nearly 50% of the total shrimp quality ,the maximal muscular heavy metal was observed in the total ridgetail white prawn .The findings indicate that various heavy metal contents in different tissues of the cultured ridgetail white prawn are lower than the national standard and safe for human consumption .
