title: Seasonal variations in toxic metal levels of two fish species, Mugil cephalus and Mullus barbatus and estimation of risk for children.
abstract: Concentrations of five toxic metals were determined in two fish species namely, Mugil cephalus and Mullus barbatus consumed in two neighboring Turkish cities during 2010-2011. Lead concentrations (mean 900 μg kg(-1)) for M. cephalus were found to be higher than the maximum allowances concentration (MAC) of 300 μg kg(-1). Similarly, Cr (mean 410 μg kg(-1)), Ni (mean 331 μg kg(-1)) and Cu (mean 834 μg kg(-1)) concentrations in M. cephalus were significantly higher than in M. barbatus (mean 341 μg Cr kg(-1), 256 μg Ni kg(-1) and 568 μg Cu kg(-1)). Although concentrations of some metals exceed the limits set by the authorities, the estimated non-carcinogenic and carcinogenic health risks by the Target Hazard Quotient and target carcinogenic risk indicate that there is no carcinogenic risk for humans, and the risk of developing cancer over a human lifetime is between 2 and 12 in 1,000,000.
