Polybrominated diphenyl ethers (PBDEs) have been used extensively in electrical and electronic products, but little is known about their distribution in the environment surrounding the manufacturing factories. This study reports PBDE contamination in various matrices from the location (Liushi, Zhejiang province) that produces more than 70% of the low-voltage electrical appliances in China. Additionally, PBDE contamination was compared with other industries such as the e-waste recycling business (Fengjiang) in the same region. Specifically, we measured seven PBDE congeners (BDEs - 47, 99, 100, 153, 154, 183, and 209) in water, sediment, soil, plant, and animal tissues from four different areas in this region. The present study revealed elevated PBDE concentrations in all matrices collected from Liushi and Fengjiang in comparison with highly industrialized areas without significant PBDE contamination sources. In water samples, there were large variations of PBDE content and composition across different areas. In sediment/soil and biological samples, BDE-209 was the predominant congener and this could be due to the abundant usage of deca-BDE mixtures in China. Our findings provide the very first data on PBDE contamination in the local environments surrounding the electronics industry, and also reveal widespread PBDE contamination in highly industrialized coastal regions of China.
多溴二苯醚(PBDEs)已广泛应用于电子电气产品,但对于其在制造工厂周边环境中的分布情况却知之甚少。本研究报告了中国 70%以上的低电压电器生产地——浙江省柳市镇各种基质中的多溴二苯醚污染情况。此外,还将该地区的电子废物回收业务(凤江)等其他行业的多溴二苯醚污染情况进行了比较。具体来说,我们测量了该地区四个不同地点的水中、沉积物中、土壤中、植物中和动物组织中的七种多溴二苯醚同系物(BDE-47、99、100、153、154、183 和 209)。与没有明显多溴二苯醚污染来源的高度工业化地区相比,本研究表明柳市和凤江采集的所有基质中的多溴二苯醚浓度均升高。在水样中,不同地区的多溴二苯醚含量和组成存在较大差异。在沉积物/土壤和生物样本中,BDE-209 是主要的同系物,这可能是因为十溴二苯醚混合物在中国的大量使用。本研究结果提供了关于电子电气工业周边环境中多溴二苯醚污染的首批数据,同时也揭示了中国高度工业化沿海地区普遍存在的多溴二苯醚污染问题。
