Mitigation and remediation technologies for organic contaminated soils

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 health.Physical,chemical,and biological technologies have been employed for the mitigation and remediation of organic contaminated soils.This 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,respectively.On this basis,directions for future research in this field are suggested.
