To investigate the effects of environmental factors on PAEs in soils, pollution sources were identified, and the cumulative risks of PAEs to humans through vegetables in the diet were evaluated in this study. Ninety-eight vegetable samples were collected from 10 markets along with 128 vegetable and 111 soil samples from agricultural greenhouses and open field. All soil and vegetable samples were contaminated with PAEs, and the total concentrations of the 5 PAEs, including dimethyl phthalate(DMP), diethyl phthalate(DEP), di-iso-butyl phthalate(DiBP), di-n-butyl phthalate(DnBP), and di-2-ethylhexyl phthalate(DEHP), were in the ranges of 0.26–2.53 mg kg^(-1) for soils and 0.95–8.09 mg kg^(-1) for vegetables. Three components extracted from principle component analysis could explain 51.2%, 19.8%, and 15.3% of the total variance of the 5 PAEs in soils, which may represent three major sources of PAEs, i.e., wastewater irrigation, application of fertilizers and pesticides, and plastic film. Long-term greenhouse cultivation could accumulate DEHP in soils, and a higher soil Fe Ox content reduced the Dn BP concentration. Based on a survey of vegetables in the diet, the hazard index of PAEs was < 0.15 for individuals in different cities. The exposure of PAEs through vegetable intake was higher than the total exposure from other food stuffs, inhalation, and dermal absorption. More attention should be given to controlling PAEs in greenhouse vegetables. 关键词：邻苯二甲酸酯类蔬菜大棚危险性评价农药污染农业大棚累积风险邻苯二甲酸二丁酯邻苯二甲酸二异辛酯
