| Abstract: | Borollos Lake is situated in the northern part of Nile Delta along the Mediterranean coast of Egypt between 31°21'-31°35'N and 30°31'-31°10'E.This work reveals that more than 82% of the total nipper occurs in the residual fraction.Only 4.6%,7.3% and 6.1% of the total nipper occurs in the fractions bound to carbonate,oxides and organic matters,respectively.The exchangeable-Cu is in trace amounts and the other fractions were relatively low in comparison with zinc fractions.The residual fraction of zinc reaches between 66% and 88%.The carbonate-Zn,organic-Zn and oxides fractions range from 1.3% to 7.9%,2.8% to 11.6% and 2.8% to 13.2%,respecticely.There is no pollution by Cu and Zn metals in comparison with the results previously reported for other poVuted Egyptian aquatic environments such as Mariut. |
