Hair samples and paired serum samples were collected from e-waste and urban areas in Wenling of Zhejiang Province, China. The PBDE and DBDPE concentrations in hair and serum samples from e-waste workers were significantly higher than those of non-occupational residents and urban residents. BDE209 was the dominating BFRs in hair and serum samples from the e-waste area, while DBDPE was the major BFRs from the urban area. Statistically significant correlations were observed between hair level and serum level for some substances (BDE209, DBDPE, BDE99, BDE47, BDE28, and BDE17), although the PBDE congener profiles in hair were different from those in the serum. A statistically significant positive correlation between the PBDE concentrations and the working age, as well as gender difference, was observed in e-waste workers. Different sources of PBDEs and DBDPE in three groups were identified by principal component analysis and spearman correlation coefficient. Hair is suggested to be a useful matrix for biomonitoring the PBDE exposure in humans.
在中国浙江省温岭市的电子垃圾处理区和城区采集了头发样本及配对的血清样本。电子垃圾处理工人头发和血清样本中的多溴二苯醚（PBDE）和十溴二苯乙烷（DBDPE）浓度显著高于非职业居民和城市居民。在电子垃圾处理区的头发和血清样本中，BDE209是主要的溴代阻燃剂（BFRs），而在城区，DBDPE是主要的BFRs。尽管头发中的多溴二苯醚同系物谱与血清中的不同，但观察到某些物质（BDE209、DBDPE、BDE99、BDE47、BDE28和BDE17）的头发水平与血清水平之间存在显著的统计学相关性。在电子垃圾处理工人中，观察到多溴二苯醚浓度与工作年限之间存在显著的正相关以及性别差异。通过主成分分析和斯皮尔曼相关系数确定了三组中多溴二苯醚和十溴二苯乙烷的不同来源。头发被认为是用于生物监测人体多溴二苯醚暴露的有用基质。
