人类接触来自电子垃圾的污染物是一个重要的科学问题，因为它们对健康的影响。用气相色谱-电感耦合等离子体质谱(GC-ECNI-MS)分析了天津市中国北部某电子垃圾处理场所(n=35)和对照场所(n=21)血清中的有机卤素污染物。经多元回归分析，暴露组血清中四至六、七至非二苯醚、多氯联苯、多溴联苯和二苯基二苯醚的几何平均浓度分别为2.77、12.2、44.1、0.52和7.64ng−-1脂，是对照组的1.5~7.4倍。这表明在电子垃圾场工作和/或生活与这些污染物的体内浓度升高有关。电子废物拆解工人的低蒸汽压污染物(即七至二苯醚和DP)的水平明显高于居住在电子废物场地周围的当地居民，这表明职业工人可能存在更高的暴露在这些污染物中。
Human exposure to pollutants from e-waste is an important scientific issue for their health effects. In this study, organohalogen pollutants in human serum sample from an e-waste dismantling site (n=35) and a control site (n=21), both located in Tianjin, Northern China, were analyzed using GC–ECNI–MS. Geometric mean concentrations of tetra- through hexa-BDEs, hepta- through nona-BDEs, PCBs, PBB-153, and DP in the exposure group were 2.77, 12.2, 44.1, 0.52, and 7.64ngg−1lipid, respectively, which ranged from 1.5 to 7.4-fold higher than those in the control group through multivariate regression analysis, indicating that working and/or living in the e-waste site was associated with elevated body concentrations of these pollutants. Pollutants with low vapor pressures (i.e., hepta- through nona-BDEs and DP) were at significantly higher levels for e-waste dismantling workers than for local residents living around the e-waste site, suggesting higher exposure to these pollutants might exist for the occupational workers.
