Distribution of different metals in coastal waters of Alexandria, Egypt

ABSTRACT

Seasonal variation of some heavy metals [Fe, MN, Cu, Cd, Pb, Co, Ni, Cr, Sn and Al] are estimated at surface and bottom waters from 10 stations at near-shore, Alexandria coast during 2004. Salinity [16.20-39.10] and pH values [alkaline side] were also measured. The concentrations of heavy metals are at high levels in regions receiving different effluents from wastes of El-Mex region. A comparative study between the different stations was carried out to evaluate the effect of sewage, agricultural and industrial wastes discharged into some regions of Alexandria coast. Different statistical treatments were carried out to calculate the correlation coefficients between metals and the annual average variation
