四种蔬菜对DBP和DEHP及其代谢物的吸收累积研究
Absorption and Accumulation of Di-n-butyl phthalate (DBP) and Di (2-ethylhexyl) phthalate (DEHP) and Metabolites in Four Vegetables
摘要
Abstract
The distribution and bioconcentration factor (BCF) of di-n-butyl phthalate (DBP),di (2-ethylhexyl) phthalate (DEHP) and their monoester metabolites mono-butyl phthalate (MBP),mono-2-ethylhexyl phthalate (MEHP) in four vegetables Brassica campestris L,Spinacia oleracea,Lactuca sativa and Raphanus sativus cultivated in treated soil were analyzed in this study.The samples were prepared with accelerated solvent extraction,QuEChERS and derivatization,and then measured using GC-MS/MS.DBP,DEHP and their metabolites MBP,MEHP were detected in four vegetables treated with high and low concentrations of DBP and DEHP.The total amount of DBP and DEHP residues (∑2PAEs) and their total metabolites in R.sativus were significantly higher than those in other vegetables.The BCF values of DEHP from the four vegetables were greater than 1,indicating an obvious bio-accumulation effect.However,the BCF values of DBP were much less than 1 in three vegetables except R.sativus.DBP and DEHP in the soil were absorbed by these four vegetables.And the more toxic metabolite phthalate monoesters could be found in tour vegetables.关键词
