摘要

采用野外调查采样和室内培养、分析相结合的方法

探讨蔬菜对多氯代有机污染物(PCOPs)的富集和转移特征。结果表明:不同旱地蔬菜对不同PCOPs的富集能力和转移能力各不相同

主要体现在叶菜类对六六六(HCB)的富集系数最高

根菜类对滴滴涕(DDT)类的转移系数最高等特点;不同盆栽蔬菜的富集和转移特点和旱地蔬菜的基本一致

且随着土壤受污染程度的加剧会导致其富集系数和转移系数降低

这与蔬菜生物量较小而影响其对PCOPs的富集和转移能力有关。研究结论可为了解PCOPs由土壤环境进入蔬菜体内及其在体内的转移提供科学依据。

Abstract

Bioaccumulation and translocation characteristics of polychlorinated organic pollutants(PCOPs) in vegetables were studied by using the method of field investigation and sampling

potted plant in glasshouse and laboratory analyses.Results showed that bioaccumulation and translocation factors of vegetables sampled from field were different

bioaccumulation factors of leaf-vegetables to hexachlorobenzene(HCB) were the highest

translocation factors of root-vegetables to dichloro-diphenyl-trichloroethane(DDT) were...
