Risk assessment of toxic residues among some freshwater and marine water fish species

Egypt has several beaches, as well the Nile River and a few lakes; therefore, it could compensate for lack of protein in red meat with fish. Fish, however, may become source heavy metal exposure humans. The current study was to assess level five toxic metals, lead (Pb), cadmium (Cd), mercury (Hg), arsenic (As), aluminum (Al), six species, namely, Oreochromis niloticus ( O. ) , Mugil cephalus M. Lates L. ), Plectropomus leopardus P. Epinephelus tauvina E. Lethrinus nebulosus collected from El-Obour fish market Egypt. residual concentrations tested metals examined niloticus, cephalus, tauvina, species were found be higher than European Commission's maximum permissible limits (MPL) Pb Cd by 10 20%, 15 65%, 75 15%, 20 40%, 25 5%. In contrast, 30% exceeded MPL Hg. It shown that average estimated daily intake (EDI) target hazard quotient (THQ) samples are below safety levels human consumption index (HI < 1). From health point view, this showed there no possible risk people due any studied under rate country.
