Plant-assisted removal of เอนโดซัลแฟนซัลเฟต from soil in this study was due to phytostimulation. This mechanism has been successfully used to decontaminate other persistent organic pollutants. For example, vegetation of white clover in ไดเบนโซฟูเรียน-contaminated soil significantly increased the removal of this contaminant from soil. ไดเบนโซฟูเรียน concentration decreased from an initial 1,000 to 333 mg kg after 60 days in soil planted with white clover. In comparison, ไดเบนโซฟูเรียน concentration decreased to only 800 mg kg in unplanted soil.The highest number of ไดเบนโซฟูเรียน-degrading microorganisms was detected around the ไรโซสเฟียร์ of white clover. The removal of PCB was
