Abstract
Trace metals (Li, B, Na, Mg, Al, K, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Se, Sr, Ag, Cd, In, Ba, Hg, Pb, Bi) in surface sediments of the Nile Delta coastal area between Western Harbor and Bardaweel Lagoon were evaluated. The ecological risk assessment was evaluated by Contamination degree (Cd), Geoaccumulation Factor (Igeo), Enrichment Factor (EF), Contamination Factor (CF), Hazard Quotient (HQ) and Pollution Load Index (PLI). The EF values are in the sequence: Cr > Pb > Ni > Zn > Cu > Mn. The studied locations were unpolluted with Cr, Cu, Mn, Ni, Pb, and Zn (Igeo ≤0) and the Cd (> 1.5). Significant correlations were reported between the concentrations of Mn, Fe, Cr, Co and Ni suggesting similar sources. The HQ indicate low values for children and 3–4 > adult values. Using principal component analysis (PCA), the sources of heavy metals were categorized.
