  abstract = {{C}oastal areas are sites of discharge of anthropogenic compounds, such as trace metals. {I}n seawater, trace metals have a strong affinity for particulate organic matter or clay mineral and tend to accumulate in sediments. {H}owever, natural events and human activities can cause disturbances in surface sediments involving modification of chemical balances and contamination of surrounding waters. {H}ere, we investigated the dynamics of trace metals in the {S}fax coastal area ({G}ulf of {G}ab{\`e}s, southern {M}editerranean {S}ea), a shallow coastal ecosystem impacted by tides and submitted to urban/industrial effluents. {W}e presented the spatial distribution of trace metals concentrations, their potential mobility in sediments and evaluated the potential sources of target elements in surface waters. {T}he highest concentration levels in surficial sediments (3.51 µg/g) and surface waters (0.25 µg/{L}) were found for {C}d. {T}he latter showed a great affinity (50%) for the exchangeable phase while other elements ({C}u, {C}r and {N}i) were found in most residual phases, reducing the environmental risk. {P}b and {Z}n, associated {F}e/{M}n oxyhydroxides revealed potential inputs from urban and industrial effluents. {M}ultivariate statistical analysis suggested that dissolved trace metals in surface waters were probably derived from effluents/wadis but also from sediment resuspension processes, induced by natural (tides, hydrodynamics) or anthropogenic (dredging) events. {O}verall, this study highlights the importance of the interactions between sediment and water column for the trace metal dynamics in very shallow coastal environments with an exacerbated pattern for {C}d.},
