Polychlorinated biphenyls (PCBs) were used in a number of industrial products from 1950 to 80s, including building materials. As a result, some buildings exhibit high levels of PCBs in the indoor environment. The aim of this study was to test silicone wristbands as a method for estimating personal exposure to PCBs in buildings both in controlled experiments and field settings. In the controlled study, the sampling kinetics of silicone wristbands were investigated in a 31-day uptake study. The field study focused on the application of wristbands as a personal exposure measure. It included 71 persons in a contaminated housing estate and 23 persons in a reference group. The linear uptake of PCBs ranged from 2 to 24 days for PCB-8, 18, 28, 31, 40, 44, 49, 52, 66, 99, and 101 under controlled conditions. A generic sampling rate (R_k) of 2.3 m³ d^-1 corresponding to a mass transfer coefficient of 17 m h⁻¹ was found in the controlled kinetic study. Partitioning coefficients were also determined for the nine congeners. In the field study, an apparent generic field sampling rate (R_f) of 2.6 m³ d^-1 was found; when adjusted to reported hours exposed, it increased to 3.5 m³ d^-1. The wristbands were shown to be a good tool for predicting airborne exposure, as there was a highly significant difference between the exposed and reference group as well as a clear trend when used for ranking of exposure. In correlation analyses, highly significant correlations were observed between air and wristband levels, though adjusting by self-reported exposure time only increased the correlation marginally in the field study. The obtained kinetic data can be used for estimating the magnitude of external exposure. The advantages provided by the wristbands in the form of easy use and handling are significant, though the limitations should also be acknowledged.

从 1950 年到 80 年代，多氯联苯 (PCB) 用于许多工业产品，包括建筑材料。因此，一些建筑物在室内环境中表现出高水平的多氯联苯。本研究的目的是测试硅胶腕带作为一种在受控实验和现场环境中估计个人在建筑物中接触多氯联苯的方法。在对照研究中，对硅胶腕带的采样动力学进行了为期 31 天的摄取研究。实地研究的重点是腕带作为个人暴露量的应用。它包括受污染的住宅区中的 71 人和参考组中的 23 人。在受控条件下，PCB-8、18、28、31、40、44、49、52、66、99 和 101 的 PCB 线性吸收范围为 2 至 24 天。一个通用的采样率（R_k ) 为2.3 m ³ d ^-1，对应于17 m h ^-1的传质系数在受控动力学研究中发现。还确定了九个同源物的分配系数。在实地研究中，发现明显的通用实地采样率 (R _f ) 为 2.6 m ³ d ^-1；当调整到报告的暴露小时数时，它增加到 3.5 m ³ d ^-1. 腕带被证明是预测空气传播暴露的好工具，因为暴露组和参考组之间存在非常显着的差异，并且在用于暴露排名时趋势明显。在相关性分析中，在空气和腕带水平之间观察到高度显着的相关性，尽管通过自我报告的暴露时间进行调整仅在实地研究中略微增加了相关性。获得的动力学数据可用于估计外部暴露的大小。腕带以易于使用和处理的形式提供的优势是显着的，但也应承认其局限性。
