This work aims to establish an environmental assessment of the subsurface sediment of the Southern Coast of Sfax in Tunisia based on the chemical characterization of leachates of samples taken from ten stations along the zone, in accordance with the French standard X31–211. Results indicated rates in metallic trace elements (Pb, Cu, Cr, Cd, Ni, Zn, Fe and Hg) that exceeded the limits set by the Tunisian standard for environmental protection NT.106.002 concerning the discharge of effluents in the water environment. Findings prove the obvious contamination of the study zone due to the various polluting activities in its neighborhood. A more in-depth investigation program based on the results of this work can serve as a decision support tool for the implementation of an action plan and for the development of rehabilitation scenarios of the zone. The reclamation of the Southern coast of Sfax is necessary to reinforce the sustainability of the project of depollution and development of the northern coast of the city called Taparura that was realized in 2009.

突尼斯斯法克斯南部沿海地区地下沉积物中重金属污染的评估

这项工作旨在根据法国标准X31-211，根据沿该地区十个站点采集的样品的渗滤液的化学特征，对突尼斯Sfax南部海岸的地下沉积物进行环境评估。结果表明，金属微量元素（铅，铜，铬，镉，镍，锌，铁和汞）的比率超过了突尼斯环境保护标准NT.106.002所规定的关于水环境中废水排放的限制。研究结果证明，由于研究区附近的各种污染活动，该研究区受到了明显的污染。根据这项工作的结果制定的更深入的调查方案可以作为执行行动计划和制定该区复原方案的决策支持工具。
