Determination of available heavy metal concentrations in River Nile sediments, Damietta, Egypt

The present study investigates the distribution and available concentrations of As, Co, Cu, Fe, Sb, Zn, Cd, Se, Ni, Pb in the bottom sediment of the Damietta Nile branch. Available concentrations were determined using the DTPA extraction method. The mean available concentrations were arranged as follows As > Fe > Cu > Zn > Co > Se > Ni > Pb > Sb > Cd. Clustering analysis represents a clear difference between two groups of heavy metal concentrations before and after Damietta Dam. Textural classifications and Total organic matter have been studies. The matrix correlation coefficient, comparison between other studies has been evaluated.
