  abstract = {{T}he inorganic contamination of sediment and harvested molluscs was investigated in the mangrove environment of {S}outhern {W}est {S}enegal. {T}race metals were analysed in surface sediments, two bivalves ({A}rca senilis and {C}rassostera gasar) and three gastropods ({C}onus spp., {H}exaplex duplex and {P}ugilina morio) collected from four stations: {D}ionewar, {N}iodor and {F}alia localised in the {S}aloum {D}elta, and {F}adiouth from the {P}etite {C}ote. {A} geochemical normalisation approach by using aluminium allowed for discrimination of sediment contamination among sites. {I}ndeed, {F}adiouth appeared highly contaminated with {C}d, {H}g and {N}i compared to the {S}aloum {D}elta. {F}or all mangrove sites, trace metals exhibited significant higher concentrations (on a dry weight basis) in shellfish compared to sediments, excepted for {N}i and {P}b. {T}he distribution pattern followed a similar global trend in molluscs regardless of the spatio-temporal variability, with the predominance of {Z}n (80% of total metals) followed by {C}u and {C}d. {H}owever, strong differences of metal bioavailability and bioaccumulation in biota were demonstrated, revealing the requirement of employing a suite of organism bioindicators to monitor metal contamination in mangrove ecosystems. {F}rom an ecotoxicological point of view, trace metal levels in sediments from the {P}etite {C}ote and the {S}ine-{S}aloum {E}stuary were below the effects range-low ({ERL}) threshold limit of the sediment quality guidelines for adverse biological effects ({SQG}s). {O}n the opposite, some concerns about {C}d contamination of edible shellfish from {S}outhern {W}est {S}enegal were highlighted, from both the safety point of view of local populations' health, and the chemical quality point of view of exported resources.},
