Radionuclides (Po-210 and Pb-210) and Some Heavy Metals in Fish and Sediments in Lake Bafa, Turkey, and the Contribution of Po-210 to the Radiation Dose

WOS: 000389571300072The pollution level of Lake Bafa was investigated by collecting fish samples {Dicentrarchus labrax (sea bass), Liza ramada (mullet) and Anguilla anguilla (eel)}, surface sediment, and core samples. In all these samples, Po-210 and Pb-210 concentrations were estimated, and total annual dose rates were obtained for each species. Some heavy metal (Cr, Ni, Pb, Cd, Mn, Fe, and Zn) concentration levels were obtained for the fish and a core sample. The sediment mass accumulation rate was found to be 3.27 g.m(-2) . day(-1) (0.119 g . cm(2) . y(-1)) from a core sample. The heavy metal concentrations in the vertical profile of samples from the core were also observed. The measured concentration of Zn, Pb, Cd, and Cr were between the ERL (effects range low) and ERM (effects range median) limits, while Ni concentrations were higher than the ERM limit. The observed concentrations of Cd, Pb, and Zn in fish samples did not exceed the limits in accordance with Turkish Food Regulations. Further, the maximum effective dose equivalent of Po-210 in the area was found to be 1.169 mu Sv.y(-1).Ege UniversityEge University [11 NBE 009]This work was supported by The Research Fund of Ege University No.: 11 NBE 009
