Evaluation of toxic elements As, Cd, Cr, Cu, Ni, Pb and Zn in the surficial sediments of the Red Sea (Saudi Arabia)

- Contamination of metals was studied in the surficial sediments of the Red Sea (Saudi Arabia).
- Geochemical and ecological risk assessment indices were also estimated.
- Enrichment of Ni, Zn, Fe, V, Cu and As in the deep stations was due to metalliferous nature.
- Enrichment of Cr and Mn was due to the influence of brine pools and hydrothermal circulation.
- Enrichment of Ni and Hg was due to anthropogenic activities.
