Heavy Metals in some farm fish retailed in Al-Boheira governorate.

Heavy metals are surrounded with great care and special importance due to their highly toxic effects on fish, which is a part of human diet; they affect survivability, growth and reproduction of fish. The present study has been conducted to determine heavy metals (chromium, cadmium, zinc, copper, lead and selenium) bioaccumulation in the muscles of three fish species, Common carp (Cyprinus Carpio), Nile tilapia (Oreochromis niloticus) and Mugil cephalus (striped mullet) that were collected from a different location (Damanhour, Kafr El Dawar and El Mahmoudia) along- Boheira governorate in Egypt. The results showed a statistically significant (p˂0.05) difference between fish species in the concentration of the accumulated heavy metals in muscle of examined species. It was observed that heavy metals bioaccumulation in fish were in the order of Mugil cephalus ˃ Nile Tilapia˃ Common carp, furthermore, the most of these levels within the global permissible limits for muscles samples.
