Abstract

The current study was conducted to investigate the bioaccumulation of lead (Pb), cadmium (Cd),iron (Fe) and chromium (Cr) in the muscle tissues of Tilapia, Catfish, Sea bream and Sea bass fishes collected in Autumn (2023) from Kitchener Drain and Burullus Lake, Kafrelsheikh Governorate, Egypt. For this purpose, a total of 120 muscle samples, 60 of Tilapia and Catfish (30, each) from three different areas in Kitchener Drain in the Nile river (10, each). And 60 of Sea bream and Sea bass (30, each) from three different areas in Burullus Lake (10, each) were analyzed for the heavy metals mentioned above in order to assess the health risk. Our results revealed that Fe and Cr levels in all analyzed fish samples from different areas were less than the maximum permissible limit. While Pb and Cd residues in all analyzed fish samples from all different areas were higher than the maximum permissible limit. Results showed that the highest mean levels of all tested heavy metals were recorded in southern area of Kitchener Drain and eastern area of Burullus Lake with respect to all metals. The dangerous residues for human health were shown in the following order with referring to their heights above the maximum permissible limits: Cd>Pb> Fe> Cr. In conclusion, Kitchener Drain and Burullus Lake are considered a hazardous source for lead and cadmium in fish muscles.
