摘要：
The present review was conducted to highlight the major and trace elemental composition in surface sediments from the Nile River and Egyptian Red Sea coastal areas in terms of provenance, concentrations, pollution indices, and health hazards. Health hazard due to the exposure to selected elements via inhalation, ingestion, and dermal contact was calculated. The samples were subjected to neutron activation analysis. Bivariate and multivariate statistical analysis was employed. Significant amounts of V, Cr, and Zr are observed in Nile sediments. Whereas, considerable concentrations of Br and Ca were found in marine sediments. The concentrations of the other elements are in line with the corresponding values in upper continental crust. The outcomes of the pollution indices show some localized polluted sites (Helwan, Cairo, and Delta) in Nile sediments. Likewise, in Abu Ghusun area in marine ones. Overall, the hazard index of the investigated elements in the Nile and marine sediments for both studied age criteria is higher than the tolerable values (1 x 10(-6) - 1 x 10(-4)).
