Abstract
PCBs is a kind of persistent organic pollutants.The artificial Aroclor 1248 contaminated soil was remediated by using plants(Robinia pseudoacacia and Cucurbita pepo ssp.pepo);and the remediation effects were determined with GC / MS.The results were as follows,On the 18th day after planting,the total degradation rate of PCBs by the rhizosphere of black locust was 39.7%,and the total absorption rate of PCBs by the rhizosphere of zucchini was 33.6%.On the 35th day after planting,the total degradation rate of PCBs by the rhizosphere of black locust was 58.1%,and the total absorption rate of PCBs by the rhizosphere of zucchini was 40.9%.For phytoremediation of soil pollution,it was thought that planting black locust was better.
