Assessing ecological and health risks of potentially toxic elements in marine and beach sediments of Tangier Bay, Southwestern Mediterranean sea.

This study investigates the distribution, sources, and ecological risks of potentially toxic elements (PTEs) in marine and beach sediments of Tangier Bay, Southwestern Mediterranean. Sediments from 22 locations were analyzed for physicochemical properties and concentrations of metals such as As, Cr, Zn, Cd, Pb, and Cu. Elevated levels of As (up to 40.
