Persulfate is considered a convenient and efficient remediation agent for organic contaminated ***,the potential risk of sulfur into the soil remediation by persulfate remains *** this study,glass bottles with different persulfate dosages and groundwater tables were set up to simulate persulfate remediation of organic pollutants(aniline).The results found sulfate to be the main end-product(83.0%–99.5%)of persulfate remediation after10 ***,H_(2)S accounted for 93.4%–99.4%of sulfur reduction end-products,suggesting that H_(2)S was the final fate of sulfur.H_(2)S was released rapidly after one to three days at a maximum concentration of 33.0 ppm,which is sufficient to make a person *** to the fitted curve results,H_(2)S concentration decreased to a safe concentration(0.15 ppm)after 20–85 ***,the maximum concentration of methanethiol reached 0.6 *** results indicated that secondary pollution from persulfate remediation could release harmful gases over a long ***,persulfate should be used more carefully as a remediation agent for soil contamination.

organic contaminated soils have become a widespread environmental problem,which may lead to a great threat to the quality of agricultural production and to human ***,chemical,and biological technologies have been employed for the mitigation and remediation of organic contaminated *** paper reviews the progress of mitigation and remediation technologies for organic contaminated soils and suggests two different strategies for the mitigation of‘slightlycontaminated’agricultural soils and the remediation of‘heavily-contaminated’soils/sites,*** this basis,directions for future research in this field are suggested.
