- The Bouregreg estuary represents an ecosystem which has a very important ecological and biological interest because of its fauna and flora variety which has experienced many complex releases of various origins. In the context of ecological conservation, such as the closure of the Oulja landfill (Salé city side) and the pre-treatment of wastewater (Rabat city side). This study based on the determination of ecological quality by obtaining a preliminary level assessment and distribution of six heavy metals (Fe, Zn, Cu, Cr, Pb and Cd) were measured in water and sediment to understand the level of heavy metals and their distribution at source.The samples were taken at 5 stations in the Bouregreg estuary in the Rabat/Salé region and were collected in August 2022.
