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 635μg·kg-1)and Dicentrarchus labrax(mean 463μg·kg-1)samples were found to be significantly higher than the maximum allowances concentration(MAC)of 300μg·kg-1.Mean chromium(324μg·kg-1)and Cu(940μg·kg-1)concentrations in Pomatomus saltatrix were higher than in Dicentrarchus labrax(268μg Cr·kg-1 and 600μg Cu·kg-1)while Ni in Pomatomus saltatrix(216μg·kg-1)was lower in Dicentrarchus labrax(291μg·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 2~9in 1 000 000.
The concentrations of five toxic metals were decided for two fish species, obtained from fish markets in Turkey during 2010-2011. For the determinations, AAS and ICP-AES were used. The resulting lead concentrations for all studied Pomatomus saltatrix (mean 635 μg · kg-1) and Dicentrarchus labrax (mean 463 μg · kg -1) samples were found to be significantly higher than the maximum allowances concentration (MAC) of 300 μg · kg -1 .Mean chromium (324 μg · kg -1) and Cu · Kg-1) concentrations in Pomatomus saltatrix were higher than in Dicentrarchus labrax (268 μg Cr · kg -1 and 600 μg Cu · kg -1) while Ni in Pomatomus saltatrix (216 μg · kg -1) 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 1 000 000.
