植物吸收和降解水体中多氯代有机污染物的作用

PRIMARY STUDY ON PHYTOREMEDY OF CONTAMINATED WATER WITH PCOPs

对黑麦草吸收和降解水中以1,2,4TCB和pp′DDT为代表的PCOPs进行了初步研究。结果表明,黑麦草能不同程度吸收和降解1,2,4TCB和pp′DDT,降低水中PCOPs含量。与吸收和降解土壤中PCOPs的能力相比,黑麦草修复受PCOPs污染水体的能力相对较弱。

Phytoremediation of contaminated water with PCOPs (1,2,4-TCB and pp′-DDT) were studied by the method of water-culture medium.Results showed that ryegrass could absorb and degrade 1,2,4-TCB and pp′-DDT,reduce the content of PCOPs in water.The growth of ryegrass was affected by the variety and concentration of PCOPs.The absorption capability of ryegrass in water was lower than in soil.
