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 ΣPBDE in in-house dust (38,685ng/g dw) was higher than that in out-house dust (24,595ng/g). For food samples, the highest concentration of ΣPBDE was found in fish and shellfish (2755ng/kg ww), followed in descending order by eggs (2423ng/kg), cereals (2239ng/kg) and meat (1799ng/kg). The estimated total daily dietary intake of PBDEs was 1671ng/day for adults and 952ng/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.
本研究旨在评估中国南方电子废物回收地区通过两种主要暴露途径（灰尘和饮食）接触多溴二苯醚（PBDEs）的人体风险。通过气相色谱/质谱法（GC/MS）对 134 个灰尘样本和 129 个食品样本进行了分析。室内灰尘中ΣPBDE 的平均浓度（38685ng/g dw）高于室外灰尘（24595ng/g）。对于食品样本，ΣPBDE 的最高浓度出现在鱼类和贝类（2755ng/kg ww），其次是蛋类（2423ng/kg）、谷物（2239ng/kg）和肉类（1799ng/kg）。成年人每天通过饮食摄入的 PBDE 总量估计为 1671ng，儿童为 952ng。本研究表明，对于儿童而言，灰尘摄入是 PBDE 的主要暴露途径，而对于成年人而言，饮食摄入是 PBDE 的主要暴露途径。我们的研究结果表明，在电子废物回收中心采集的灰尘和食品样本中存在高浓度的 PBDE，这对该地区居民，尤其是儿童的健康构成了重大威胁。
