以8个玉米品种和3种牧草品种（紫花苜蓿、黑麦草和大刍草）为研究对象，研究了邻苯二甲酸二（2-乙基己基）酯（DEHP）在土壤中（浓度为117.4 +/- 5.2mg kg(-1)）的吸收、积累和消散。结果表明，处理40d后，DEHP去除率为66.8%（对照）~ 87.5%（华农1号）。前10天的去除率高于随后几天。植物显著增强了土壤中DEHP的耗散。与非植物土壤相比，种植土壤对DEHP的耗散量增加了13.3 ~ 122mgpot(-1)，净去除初始DEHP的2.2% ~ 20.7%。植物吸收对增强耗散总量的贡献为
This study was conducted to investigate the uptake, accumulation and the enhanced dissipation of di(2-ethylhexyl) phthalate (DEHP) spiked in soil (with a concentration of 117.4 +/- 5.2mg kg(-1)) by eleven plants including eight maize (Zea mays) cultivars and three forage species (alfalfa, ryegrass and teosinte). The results showed that, after 40days of treatment, the removal rates of DEHP ranged from 66.8% (for the control) to 87.5% (for the maize cultivar of Huanong-1). Higher removal rate was observed during the first 10days than the following days. Plants enhanced significantly the dissipation of DEHP in soil. Enhanced dissipation amount in planted soil was 13.3-122mgpot(-1) for DEHP, and a net removal of 2.2%-20.7% of the initial DEHP was obtained compared with non-plant soil. The contribution of plant uptake to the total enhanced dissipation was
