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 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 (940 μg·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) was lower in Dicentrarchus labrax (291 μg·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 29 in 1 000 000.
