Bioaccumulation of Metals in Silver Carp and Stone Moroko From Zarivar Wetland in Kurdistan Province, Iran

This research aims to monitor the trace elements content (cr, cu, pb, cd, ag, al, mn, mg, zn and fe) in the tissues of the muscle and liver of silver carp (h. molitrix ) and stone moroko (p. parva) from zarivar wetland in western iran. this research was crosssectional. the research specimen was fish caught from zarivar wetland. metal concentration analysis was carried out utilizing an icp. findings indicate presence of fe and pb in the liver, zn and cd in the muscle hadthe highest and lowest metal concentration accumulated, respectively. the trace elements content in the liver tissue was higher than those in the muscle tissue of h. molitrix and p. parva. moreover, the hazard quotients for an adult with mean of 71.5 kg was below 1 based on trace elements levels. though, the mean concentrations of trace elements in the muscle of h. molitrix and p. parva was lower than international standards. according to the uptake and distribution, these elements require periodic monitoring in the human body.
