- 摘要：以华南某城市的30名高校食堂餐饮从业人员（男女各半）作为样本,采集裸露皮肤部位（额头、手掌）和衣物遮蔽皮肤部位（前臂、小腿）的擦拭样品,通过气相色谱-质谱联用技术（GC-MS）测定了样品中13种多溴联苯醚（PBDEs）的含量并计算暴露剂量.研究发现,13种PBDEs在所有样品中均有不同程度的检出率（4.2%~91%）, 表现为Deca-BDE（73%）＞Octa-BDE（66%）＞Penta-BDE（38%）；男性样品的PBDEs平均检出频率（57%）相对高于女性（46%）.所有样品的PBDEs浓度范围为1.7~3915 ng/m2,不同采样皮肤部位间的PBDEs浓度差异显著（P＜0.0001）,表现为额头＞手掌＞前臂＞小腿. 皮肤暴露剂量（DADderm）和手-口接触暴露剂量（DADoral）的范围分别为1.9×10-4~0.026和0.014~1.0 ng/(kg·d),头颈部是DADderm贡献率最高的皮肤部位（77%）.尽管女性的DADderm和DADoral均高于男性,但差异不显著（P＞0.05）.健康风险评价结果表明,所有样本的皮肤及手-口接触致癌风险均处于可接受水平范围（＜10-4）,但女性的手-口接触致癌风险相对较高.
- Abstract：This study offers a detailed analysis of exposure to thirteen polybrominated diphenyl ethers (PBDEs) among thirty university catering staff members (balanced gender distribution) in Southern China. Sampling involved wipe tests from both skin regions exposed to air and those covered by clothing, specifically targeting the forehead, palms, forearms, and calves. The subsequent analyses, utilizing Gas Chromatography-Mass Spectrometry (GC-MS), assessed the concentration levels of PBDEs and quantified exposure dosages. PBDEs were detected in all samples at varying rates (4.2% to 91%), with Deca-BDE (73%), Octa-BDE (66%), and Penta-BDE (38%). Male participants showed a higher average detection frequency (57%) compared to females (46%). Notably, concentrations of PBDEs showed significant variance, ranging from 1.7 to 3915 ng/m2, with marked differences observed between different sampled skin areas (P<0.0001). Dermal exposure doses (DADderm) ranged from 1.9×10-4 to 0.026 ng/(kg·d), and hand-to-mouth exposure doses (DADoral) from 0.014 to 1.0 ng/(kg·d). The head and neck area contributed significantly (77%) to the total DADderm. Although women exhibited higher DADderm and DADoral levels compared to men, these differences were not statistically significant (P>0.05). Comprehensive health risk assessments confirmed that both dermal and hand-to-mouth exposure to PBDEs remained within acceptable carcinogenic risk thresholds (<10-4), with females showing marginally higher hand-to-mouth carcinogenic risks.
