title: [Accumulation of di-(2-ethylhexyl) phthalate in various genotype Ipomoea aquatica-paddy soil system].
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.
