Waste electrical and electronic equipment (E-waste) recycling provides post-consumption economic opportunities, can also exert stress on environment and human health. This study investigated emissions, compositional profiles, and health risks associated with polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) at five workshops (electric blowers to treat mobile phones (EBMP), electric heating furnaces to treat televisions (EHFTV) and routers (EHFR), and rotatory incinerators to treat televisions (RITV) and hard disks (RIHD)) within an e-waste dismantling industrial park. Total suspended particulate (TSP), PBDE, and PCB concentrations were 490-1530 μg m, 26.6-11,800 ng m and 6.4-19.8 ng m in different workshops, respectively. Tetra-BDEs were dominant in TV recycling workshops, whereas deca-BDEs were in other workshops. BDE-47, -99, and -209 were the most abundant PBDEs during e-waste recycling activities (expect in RIHD workshop). Penta-CBs were present at high levels in TV workshops, as were tetra-CBs in RIHD workshop. Low brominated BDEs contributed a large portion during working and non-working time. The percentages of octa-BDEs and nona-BDEs were higher during non-working than working time. PBDEs posed a higher non-cancer risk; PCBs posed cancer risk to workers through inhalation in TV workshops. This study provides insights into environmental characterization of PBDEs and PCBs during e-waste recycling processes.
电子废物（WEEE）回收提供了消费后的经济机会，但也对环境和人类健康造成压力。本研究调查了五个车间（用于处理手机的电动风机（EBMP）、用于处理电视和路由器的电加热炉（EHFTV 和 EHFR）、用于处理电视和硬盘的旋转式焚烧炉（RITV 和 RIHD））中多溴二苯醚（PBDE）和多氯联苯（PCB）与聚溴二苯醚（PBDE）和多氯联苯（PCB）相关的排放、组成特征和健康风险。不同车间的总悬浮颗粒物（TSP）、PBDE 和 PCB 浓度分别为 490-1530μg/m、26.6-11800ng/m 和 6.4-19.8ng/m。在电视回收车间，四溴二苯醚占主导地位，而在其他车间则为十溴二苯醚。在电子废物回收活动中，BDE-47、-99 和 -209 是最丰富的 PBDE（除了 RIHD 车间）。五氯苯在电视车间含量较高，四氯苯在 RIHD 车间含量较高。低溴化 BDE 在工作和非工作时间都占有很大比例。在非工作时间，八溴和九溴的比例高于工作时间。PBDE 造成了更高的非癌症风险；在电视车间，通过吸入，PCBs 对工人造成了癌症风险。本研究为电子废物回收过程中 PBDE 和 PCB 的环境特征提供了深入了解。
