Analysis And Pollution Assessment of Some Trace Heavy Metals in Freshwater, Drinking Water, Fish, and Sediments Samples in Suez Canal Region, Egypt by Flame Atomic Absorption Spectrometer

Monitoring of pollution levels of heavy metals in freshwater is significant to human health and environmental management. The objective of the current study was to monitor the freshwater quality in Suez Canal region, Egypt and to determine the efficacy of water treatment system in the removal of contaminates like heavy metals residues. The concentrations of some heavy metals (As, Cd, Cr, Pb, Hg, Ni, Cu, Mn) were determined in freshwater, treated water, in muscle of fish species (Tilapia nilotica) and sediment. The results of the study revealed that , all heavy metals concentrations in freshwater and treated water were within the permissible limits except, Lead concentration in treated water was higher than the permissible limits. In Port Said, all metals concentrations in both freshwater and treated water samples were within the permissible limits. Fish samples collected from the three governorates showed an increase in Cd and Pb levels. The heavy metals concentrations in sediment samples were remarkably high.
