This work reveals that more than 82 % of the total copper occurs inthe residual fraction. Only 4. 6%, 7. 3% and 6. 1% of the total copper occurs in the fractions bound to carbonate, oxides and organic matters, respectively. The exchangeable-Cu is in trace amounts and the other fractions were relativelylow in comparison with zinc fractions. The residual fraction of zinc reaches between 66% and 88%. The carbonateZn, organic-Zn and oxides fractions range from 1.3% to 7.9%, 2.8% to 11.6% and 2.8% to 13.2%, respectively. There is no pollution by Cu and Zn metals in comparison with the results previously reported for other polluted Egyptian aquatic environments such as Mariut.展开更多
