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.

在空气污染的流行病学研究中，对个人暴露或室内/室外空气环境的可靠知识是一个重要因素。在人类全部暴露的概念中，个人接触空气污染物取决于人们的活动。被动采样器的使用正在受到关注，作为衡量实际个人暴露的一种手段，可以通过正确的采样器来衡量，而不会扰乱每日人类活动。开发了用于测量低水平，时间加权的平均浓度，用于测量二氧化氮，一氧化碳，二氧化碳和臭氧的无源采样器。采样器是紧凑，廉价，无害且易于使用的。在实验室设置中，已经测试了使用此类采样器期间环境因素的准确性，精度和影响。采样器的特性适用于个人/环境暴露研究和室内/室外空气污染监测的大规模尺度。风洞实验的实验室测量值可用于使用indoor Air的四个Yanagisawa徽章的方差（CV）值（CV）值为3.3％。使用三个Yanagisawa徽章（C_X）和Saltzman方法（C_Y）同时测量户外二氧化二氧化碳浓度，并在21个监测地点进行。这三个徽章的CV值范围为2.5％至16.9％，Saltzman方法的比较给出了回归方程，相关系数为0.957。
