Abstract: The toxicity of persistent toxic substances (PTS) in sediments and the present remediation technologies for PTS polluted sediments and their main questions were reviewed in this paper.Furthermore,the authors pointed out that the combination of plants with microorganisms technologies should be the future trend for remedying such sediments in shallow lakes;while physiochemical biological technologies should be used in reservoirs and deeper lakes in the furture.The final purpose of such remediation is to obtain non toxic and resources disposal of PTS polluted sediments on the basis of dredging and ecological cleaning.
