Abstract
Heavy meals are more serious pollutants in a natural environment due to their toxicity, persistence and bioaccumulation problems thus fish species will not be safe for human consumption.
Many studies showed that fish accumulate these heavy metals from the surrounding water thereby leaving a health risk if taken as food. Therefore, there is an urgent need for continual assessment of the level of pollution of the water with heavy metals.
Heavy metals are non-biodegradable, inorganic chemicals that tend to accumulate overtime in the bodies of organisms due to inability to metabolize them.
The main objectives of the current study were to assess the levels of some heavy metals (Cd, Pb, Cr, Cu and Zn) in grey mullet fish collected from two fish farms; the first was a private fish farm in Idku and the second was a governmental fish farm in Behera Governorate, Egypt during winter and summer 2019 in order to evaluate the impact of these metals on the health of the consumers. Moreover, those five heavy metals were determined in irrigation and farm water of both two fish farms to estimate the effect of water on level of heavy metals.
