| Abstract | ||
| The present study was conducted on 90 random samples of fish of Claris gariepinus, Oreochromis niloticus and Mugil cephalus and shellfish of Oyster, Shrimp and Crab (15 of each) were collected from different fish markets in Kalyobia governorate, Egypt, for determination of their content of mercury, lead and cadmium. The obtained results recorded that, the mean value of concentrations with mg/kg of mercury; lead and cadmium in fish samples were 1.62 ± 0.15, 1.29 ± 0.12, 0.95 ± 0.08;0.67 ± 0.09, 0.53 ± 0.06, 0.36 ± 0.05 and 0.25 ± 0.03, 0.19 ± 0.01, 0.14 ± 0.01 for C. gariepinus, O. niloticus and M. cephalus, respectively. Meanwhile, in shellfish samples they were 1.37 ± 0.16, 1.14 ± 0.10, 0.73 ± 0.09;0.56 ± 0.07, 0.48 ± 0.05, 0.40 ± 0.04 and 0.22 ± 0.02, 0.15 ± 0.01, 0.12 ± 0.01 for oyster, shrimp and crab, respectively. Moreover, the results revealed that,the highest mercury contamination was in Claris gariepinus followed by oyster; O. niloticus; shrimp; M. cephalus and finally crab. Whereas the highest lead contaminations were in C. gariepinus followed by oyster; O. niloticus; shrimp; crab and finally M. cephalus. Moreover, for cadmium the highest ratio in in C. gariepinus followed by oyster; O. niloticus; shrimp; M. cephalus and finally crab. | ||
