Pesticide and PCB residues in biotic and abiotic environment in Lake Bafa

14493

In this study, the residues of organic pollutants such as agricultural pesticides and industrial based PCBs were measured in the Bafa Lake based on gray mullet (Mugil cephalus, Linnaeus 1758) and coastal sediments during 2010-2011 and these organochlorinated compounds were assessed to provide a better understanding of recent distribution, possible sources as well as potential biological risk of DDTs and PCBs in this area. In terms of DDT and its metabolites, it has been found that level of DDT pollution in the Bafa Lake is quite low when compared with the surface sediments of the lakes in the different regions of the world. The results indicated that Endrin was the predominant OCP contaminant in the sediments. According to sediment quality guidelines DDT and its metabolites, Dieldrin, Lindan and Heptachlor levels measured in the sediment samples showed no adverse effect on aquatic environment. ΣPCB concentrations at stations located near the industrial organizations higher than effect range low but all other stations will not pose risks to ecological risk to the bottom-dwelling consumers. BSAF (Biota and Sediment Accumulation Factor) of total OCPs for the liver tissue of ranged from 0.44 to 3.16. When considering pollutant concentrations measured in Mugil cephalus samples from Bafa Lake, it has been determined that Estimated Daily Intake (EDI) values of Aldrin, Dieldrin, Endrin, Heptaklor and DDT metabolites were far below the Acceptable Daily Intake (ADI) values recommended by (FAO/WHO). Furthermore, PCB levels in fish samples exceeded the acceptable daily intake recommended by WHO.
