Abstract

The trace concentrations of a number of elements including: Ti, Cr, Mn, Fe, Co, Zn and Ag have been determined in sediments taken from El-Ryah El Twfiky and some of its extensions through El-Kallobia, El-Dakahlia and Damietta provinces, Egypt, where these water streams are considered the main source for drinking, irrigation and industrial waters, to the three mentioned provinces. The concentration value of the trace elements have been determined and associated with the specific surface area, organic carbon, fraction of particles ( < 100 µ m) and with each other. The levels of metal concentration are compared generally with levels found elsewhere in some river sediments. The high values and trends in metal content of the sediments compared with natural levels may be ascribed to the dumping of metallic waste materials nearby the water course, industrial and domestic effluents discharged into the stream from a number of outfalls within the area, in addition to fertilizers washed down from cultivated land.
