项目摘要

Reliable knowledge of individual exposure or indoor/outdoor air environment to air pollutants is an important element in an epidemiological study of air pollution. Within the concept of total human exposure, personal exposure to air pollutants depend on people's activities. Use of passive samplers is receiving attention as a means to measure actual personal exposure can be measured by the correct sampler without disturbing daily human activity. Passive samplers for nitrogen dioxide, nitrogen monoxide, sulfur dioxide, carbon monoxide, and ozone were developed to measure low-level, time-weighted average concentrations. The sampler is compact, inexpensive, non-hazardous, and easy to use. The accuracy, precision, and effects of environmental factors during the use of such samplers have been tested in laboratory set-ups. The properties of the sampler are applicable to large-scale of both personal/environmental exposure study and indoor/outdoor air pollution monitoring.Laboratory measurements in the wind tunnel experiments gave coefficient of variance (cv) values of 3.3% for four Yanagisawa badges using indoor air. Simultaneous measurements of outdoor nitrogen dioxide concentration using three Yanagisawa badges (C_x) and the Saltzman method (C_y) were carried out at 21 monitoring sites. The cv values for the three badges ranged from 2.5 to 16.9%, and a comparison of the Saltzman method gave the regression equation with a correlation coefficient of 0.957.

对个人暴露于空气污染物或室内/室外空气环境的可靠知识是空气污染流行病学研究的重要内容。在人类总暴露的概念中，个人暴露在空气污染物中取决于人们的活动。被动采样器的使用引起了人们的注意，因为它是一种测量实际个人暴露的手段，可以通过正确的采样器测量，而不会干扰人类的日常活动。开发了二氧化氮、一氧化氮、二氧化硫、一氧化碳和臭氧的被动采样器，以测量低水平的时间加权平均浓度。该采样器结构紧凑、价格低廉、无害、使用方便。这种取样器在使用过程中的准确度、精密度和环境因素的影响已在实验室装置中进行了测试。该采样器的性能适用于大规模的个人/环境暴露研究和室内/室外空气污染监测。风洞实验中的实验室测量给出了使用室内空气的四个柳泽徽章的变异系数(Cv)为3.3%。在21个监测点用3个柳泽牌(Cx)和Saltzman法(Cy)同时测量了室外二氧化氮浓度。三种徽章的CV值从2.5%到16.9%不等，与Saltzman方法比较得出回归方程，相关系数为0.957。
