title: Variations in toxic metal levels of two fish species, Pomatomus saltatrix and Dicentrarchus labrax, and risk estimation for children.
abstract: The concentrations of five toxic metals were monthly determined in two fish species, obtained from fish markets in Turkey during 2010-2011. For the determinations, AAS and ICP-AES were used. The obtained lead concentrations for all studied Pomatomus saltatrix (mean 635 microg x kg(-1)) and Dicentrarchus labrax (mean 463 microg x kg(-1)) samples were found to be significantly higher than the maximum allowances concentration (MAC) of 300 microg x kg(-1). Mean chromium (324 microg x kg(-1)) and Cu (940 microg x kg(-1)) concentrations in Pomatomus saltatrix were higher than in Dicentrarchus labrax (268 microg Cr x kg(-1) and 600 microg Cu x kg(-1)) while Ni in Pomatomus saltatrix (216 microg x kg(-1)) was lower in Dicentrarchus labrax (291 microg x kg(-1)). The estimated non-carcinogenic and carcinogenic health risks by the Target Hazard Quotient and target carcinogenic risk indicate that there are no sytemic effects, and the risk of developing cancer over a human lifetime is between 2-9 in 1000000.
