Dermal absorption of gaseous chemicals is an important contributor to increased health risk and has yet to be adequately addressed due to the lack of available sampling techniques. In the present study, a novel personal passive sampler consisting of a housing (embracing a polydimethylsiloxane (PDMS) disk as the sorbent phase, a membrane filter, and a stainless-steel mesh) and a watchband (traditional wristband) was constructed and used to characterize gaseous phthalates (PAEs) near the air–skin interface. In a real-life setting, the utility of the passive sampler was validated by comparing the composition profiles of PAEs in the PDMS disks and in active samples and watchbands. The compositions of PAEs were consistent in disks and gaseous constituents from ambient air, with low-molecular-weight (<306 g mol–1) PAEs accounting for 87–100% and approximately 100%, respectively. Appreciable amounts of diisononyl phthalate, diisodecyl phthalate, dinonyl phthalate, and skin lipid (e.g., squalene) were detected in watchbands but not in disks. Apparently, the passive sampler can prevent particles and skin-related chemicals from adhering to the disk and collect gaseous PAEs only. The vast majority of PAEs in watchbands was associated with nongaseous constituents. The present study demonstrated that the sampling strategy is a key factor in exposure assessment.

一种用于收集气态邻苯二甲酸盐的新型个人被动采样器

气态化学品的皮肤吸收是增加健康风险的一个重要因素,由于缺乏可用的采样技术,尚未得到充分解决。在本研究中,一种新型个人被动采样器由外壳(包含聚二甲基硅氧烷 (PDMS) 盘作为吸附剂相、膜过滤器和不锈钢网)和表带(传统腕带)组成并用于表征空气-皮肤界面附近的气态邻苯二甲酸酯 (PAE)。在现实生活中,通过比较 PDMS 磁盘和主动样本和表带中 PAE 的组成概况,验证了被动采样器的效用。PAEs 的组成在圆盘和来自环境空气的气态成分中是一致的,具有低分子量 (<306 g mol –1) PAEs 分别占 87-100% 和大约 100%。在表带中检测到可观数量的邻苯二甲酸二异壬酯、邻苯二甲酸二异癸酯、邻苯二甲酸二壬酯和皮肤脂质(例如角鲨烯),但在磁盘中未检测到。显然,被动采样器可以防止颗粒和与皮肤相关的化学物质粘附在磁盘上,并且只能收集气态 PAE。表带中的绝大多数 PAE 与非气体成分有关。本研究表明,采样策略是暴露评估的关键因素。
