本研究旨在评估中国南方电子废物回收区多溴联苯醚（PBDEs）暴露的两种主要暴露途径（灰尘和饮食）的人体风险。采用气相色谱/质谱联用仪（GC/MS）对134个粉尘样品和129个食品样品进行了分析。室内灰尘中Sigma多溴二苯醚的平均浓度（38，685纳克/克干重）高于室外灰尘（24，595纳克/克）。在食物样本中，四溴二苯醚浓度最高的是鱼类和贝类（2755纳克/千克湿重），其次是鸡蛋（2423纳克/千克）、谷物（2239纳克/千克）和肉类（1799纳克/千克）。估计成人每日从膳食中摄入的多溴二苯醚总量为1，671纳克/天，儿童为952纳克/天。本研究表明，粉尘摄入是儿童多溴联苯醚的主要暴露途径，膳食摄入是成人多溴联苯醚的主要暴露途径。我们的研究结果显示，在电子垃圾回收区中心收集的灰尘和食物样本中多溴二苯醚浓度很高，这引起了该地区居民，特别是儿童的严重健康问题。(C)2014爱思唯尔有限公司版权所有。
This study was designed to estimate the human risk to polybrominated diphenyl ethers (PBDEs) exposure via two main exposure routes (dust and diet) in an e-waste recycling area in southern China. A total of 134 dust samples and 129 food samples were analyzed by gas chromatography/mass spectrometry (GC/MS). The mean concentration of Sigma PBDE in in-house dust (38,685 ng/g dw) was higher than that in out-house dust (24,595 ng/g). For food samples, the highest concentration of EPBDE was found in fish and shellfish (2755 ng/kg ww), followed in descending order by eggs (2423 ng/kg), cereals (2239 ng/kg) and meat (1799 ng/kg). The estimated total daily dietary intake of PBDEs was 1671 ng/day for adults and 952 ng/day for children. The present study indicated that dust intake was the dominant PBDE exposure route for children, and the dietary intake was the dominant PBDE exposure route for adults. Our findings revealed high PBDE concentrations in dust and food samples collected at the center of e-waste recycling area, raising significant health concerns for residents in this particular region, especially for children.
