摘要： The uptake and accumulation of di-n-butyl phthalate (DBP) in six leafy vegetables was investigated under hydroponic conditions. The test vegetables were six varieties of Brassica campestris ssp., including Kangresijiqing (KRSJQ), Xiadiqing (XDQ), Ziyoucai (ZYC), Aijiaohuang (AJH), Shanghaiqing (SHQ) and Gaogengbai (GGB). The root concentration factor (RCF), translocation factor (TF) and transpiration stream concentration factor (TSCF) were calculated in order to compare the difference of uptake and accumulation behaviours of DBP in vegetable varieties. The results showed that DBP was easily concentrated in vegetable roots, but was poorly translocated from the roots to the shoots. Among the six vegetables, the ability of concentrating DBP from the solution to shoots was the highest in GGB, followed by ZYC, KRSJQ, AJH, SHQ and XDQ. High concentrations of DBP (5.0 mg/L) seem to inhibit normal physiological activity in the vegetables, which resulted in a higher RCF and a lower TF and TSCF than in low-concentration treatment. The results will help to evaluate the safety of agricultural products and to provide evidence for screening DBP pollution-safe vegetable cultivars.
