摘要
通过实验对比研究植物(油菜)修复、微生物(甲基营养型芽孢杆菌(Bacillus methylotrophicus))修复、表面活性剂(聚氧乙烯山梨醇酐单硬脂酸酯(Tween 60))以及联合修复技术对双对氯苯基三氯乙烷(DDT)污染土壤的DDT去除效果。结果表明:以植物-表面活性剂-微生物共同作用下的DDT去除效果最好,土壤DDT去除率达到52.44%;油菜不仅可有效去除土壤中残留的DDT,同时只在地下部分对DDT进行了微量吸收,但没有进行转运,防止了农药在油菜可食部位的累积,保障了食品与生产安全。
The experiments on phytoremediation (oilseed rape),microbial remediation ( Bacillus methylotrophicus ),surface active agent (polyoxyethylene sorbitan monostearate (Tween 60)) and its combined remediation techniques of DDT contaminated soil were carried out. The DDT removal effects of different techniques were compared. The results showed that the DDT removal effect of plant-surfactant-microbe was the best. And the DDT removal rate of plant-microbe-surfactant was 52.44%. Oilseed rape could effectively remove the residual DDT from soil. However,DDT was absorbed by the root and not transported upward. This prevented the accumulation of pesticides in edible parts of oilseed rape,and ensured food and production safety.
