The concentration and composition of PBDEs in the soils and plants near a typical e-waste recycling site in South China were investigated. The total concentration of PBDEs (ΣPBDEs) in soil ranged from 4.8 to 533 ng/g dry wt. The ΣPBDEs in vegetation were from 2.1 to 217 ng/g dry wt. For the vegetable, the highest concentration of 19.9 ng/g dry wt. was observed in the shoot of Brassica alboglabra L. BDE 209 was the predominant congener in all samples. In comparison with other e-waste contaminated sites in China, lower concentrations of PBDEs and higher concentrations of PCBs were observed in both soils and plants suggesting different e-waste types involved in the present study. The PBDEs contaminated vegetables around the e-waste dismantling site may pose a potential health risk to the local inhabitants.
研究了华南典型电子废物拆解场地附近土壤和植物中多溴二苯醚的浓度和组成。土壤中多溴二苯醚的总浓度（ΣPBDEs）范围为 4.8 至 533ng/g 干重。植被中的 ΣPBDEs 范围为 2.1 至 217ng/g 干重。对于蔬菜，在 Brassica alboglabra L. 的茎叶中观察到最高浓度为 19.9ng/g 干重。在所有样品中，BDE 209 是主要的同系物。与中国其他受电子废物污染的地点相比，本研究中土壤和植物中的多溴二苯醚浓度较低，多氯联苯浓度较高，表明涉及的电子废物类型不同。电子废物拆解现场周围受多溴二苯醚污染的蔬菜可能对当地居民构成潜在健康风险。
