| 摘 要： | 在邻苯二甲酸(2-乙基己基)酯(DEHP)不同污染程度的水稻土上盆栽不同品种通菜，应用GC／MS联机检测技术研究了通菜-土壤系统中DEHP的环境行为与归宿．结果表明，通菜中DEHP的含量为0．335～12．710mg·kg^-1，与土壤的污染程度呈正相关．不同品种通菜之间对DEHP的吸收累积效应存在显著差异，与其叶子大小存在一定的正相关关系．种植不同品种通菜后土壤中DEHP的残留量(1．424～19．834mg·kg^-1)存在显著差异．通菜对土壤中DEHP的BCFs都小于1．0，与土壤的污染程度呈负相关．不同通菜品种的BCFs之间存在显著差异，中等叶子通菜品种的BCFs相对较大。 |

| Abstract: | Various genotypes of Ipomoea aquatica were pot-cultured on paddy soils with different pollution level of di-(2-ethylhexyl) phthalate (DEHP),and the concentrations of DEHP in plant and soil were determined by GC/MS.The results showed that the concentration of DEHP in plant varied directly with soil pollution level,and different genotypes of Ipomoea aquatica had significantly different concentrations of DEHP,which varied directly with leaf area.Soils grown with various genotypes of Ipomoea aquatica also had significantly different DEHP concentrations.The soil DEHP bioaccumulation factors (BCFs) of various Ipomoea aquatica genotypes were all under 1.0 and in inverse proportion to soil pollution level.The BCFs varied significantly among the genotypes of Ipomoea aquatica,with a relatively higher value for those genotypes with middle size leaves. |
| Keywords: | di(2-ethylhexyl) phthalate (DEHP) Ipomoea aquatica Paddy soil Accumulation |
