  ABSTRACT: This study assesses the contamination of sediments in Aby Lagoon, specifically in the Étuessika-Assinie Canal sector, by trace metals (Cd, Ni, Pb, Hg, Zn, As, Cr, Cu). ICP-MS analyses reveal concentrations far exceeding the geochemical background values of the upper continental crust (UCC), confirming severe pollution. Maximum levels reached 52.19 mg/kg for cadmium (Cd), 453.20 mg/kg for nickel (Ni), and 1186.99 mg/kg for lead (Pb). Geochemical indices (enrichment factor, geoaccumulation index) suggest contamination of predominantly anthropogenic origin, probably linked to artisanal gold mining as well as agricultural and urban discharges. Ecotoxicological assessment highlights a high risk for benthic organisms and a potential threat to local populations.
