  • 摘要: 为了解土壤高污染的废弃塑料处置地植物体多溴二苯醚（PBDEs）累积水平，对废弃塑料处置地13种典型植物中21种多溴二苯醚的浓度水平、组成和污染特征进行了研究.结果表明，该区域植物中∑PBDEs含量为11.3—122 ng·g-1，平均为51.2 ng·g-1，与我国电子废物处置地植物体污染水平相似，远高于一般区域植物体PBDEs污染水平.不同植物体内PBDEs的含量差异较大，其中牵牛花中PBDEs的含量最高，牛筋草中PBDEs含量最低.废弃塑料处置地植物体中BDE 209的含量为10.8—116 ng·g-1，为最主要的PBDEs同系物单体，平均占∑PBDEs的96.9%以上.其余单体中，以BDE 47和BDE 208等含量相对较高，但占总PBDEs总含量均不到1%.废弃塑料处置地植物体较电子废物处置地和一般区域植物体表现出更明显的十溴二苯醚污染特征.
    Abstract: Levels and profiles of polybrominated diphenyl ethers (PBDEs) were investigated in 13 plants from a typical plastic waste recycling site in north China, in order to understand the plant accumulation in the heavily polluted soils. The investigated results showed that the concentrations of 21 congeners of PBDEs ranged from 11.3 to 122 ng·g-1 dry weight (dw), with a mean value of 51.2 ng·g-1 dw. Compared with some previous studies, the results showed that PBDE levels in plants in this study were similar to those in some e-waste recycling areas, but much higher than those in other general areas. There was obvious difference among the plants. The highest concentration of PBDEs was detected in Pharbitis nil (Linn.) Choisy. BDE 209 was the dominant congener (mean 96.9%) in all samples, which ranged from 10.8 to 116 ng·g-1. Among the other congeners, BDE 47 and BDE 208 were relatively higher but accounted for less than 1% of the total concentrations of 21 congeners. The PBDE congener profiles in these plant samples from our studied area exhibited more distinguishable sources from deca-BDE products than those in e-waste recycling areas and other areas.
