美国环境保护署最近进行了三角研究公园颗粒物小组研究。这是一项为期一年的PM和相关共污染物调查，涉及居住在北卡罗来纳州RTP地区的参与者。主要目标是描述环境和住宅PM测量值与个人暴露监测结果之间的关系，并估计环境源对个人和室内质量浓度的贡献。共有37个家庭的38名参与者参与了个人、住宅室内、住宅室外和环境PM2.5暴露监测。参与者是30名非吸烟的高血压非裔美国人，居住在中低SES社区（北卡罗来纳州罗利SE）和8名植入心脏除颤器的个体（北卡罗来纳州教堂山）。还进行了住宅和环境PM10和PM10-2.5的监测（粗糙的差异）。研究人员在四个季节（2000年夏季、2000年秋季、2001年冬季、2001年春季）对志愿者进行了连续7天的监测。在研究期间，个人PM2.5暴露浓度在4至218微克（-3）之间。最高的个人暴露量被确定为被动环境烟草暴露的结果。随后，大约7%的个人接触试验被排除在外，以尽量减少这种污染物对整体分析的影响。结果表明，一个集合数据集（季节、队列、住所、参与者）适合调查基本的质量浓度关系。个人每日PM2.5质量浓度通常高于与其相关的住宅或环境测量值（平均个人= 23.0，室内= 19）。1、室外= 19.3，环境= 19.2马克杯m-3)。平均个人PM2.5暴露量与环境PM2.5浓度仅中度相关（r = 0.39）。Elsevier Ltd.出版。
The US Environmental Protection Agency has recently performed the Research Triangle Park Particulate Matter Panel Study. This was a 1-year investigation of PM and related co-pollutants involving participants living within the RTP area of North Carolina. Primary goals were to characterize the relationships between ambient and residential PM measures to those obtained from personal exposure monitoring and estimate ambient source contributions to personal and indoor mass concentrations. A total of 38 participants living in 37 homes were involved in personal, residential indoor, residential outdoor and ambient PM2.5 exposure monitoring. Participants were 30 non-smoking hypertensive African-Americans living in a low-moderate SES neighborhood (SE Raleigh, NC) and a cohort of eight individuals having implanted cardiac defibrillators (Chapel Hill, NC). Residential and ambient monitoring of PM10 and PM10-2.5 (coarse by differential) was also performed. The volunteers were monitored for seven consecutive days during each of four seasons (summer 2000, fall 2000, winter 2001, spring 2001). Individual PM2.5 personal exposure concentrations ranged from 4 to 218 mug m(-3) during the study. The highest personal exposures were determined to be the result of passive environmental tobacco exposures. Subsequently, similar to7% of the total number of personal exposure trials were excluded to minimize this pollutant's effect upon the overall analysis. Results indicated that a pooled data set (seasons, cohorts, residences, participants) was appropriate for investigation of the basic mass concentration relationships. Daily personal PM2.5 mass concentrations were typically higher than their associated residential or ambient measurements (mean personal = 23.0, indoor = 19. 1, outdoor = 19.3, ambient = 19.2 mug m-3). Mean personal PM2.5 exposures were observed to be only moderately correlated to ambient PM2.5 concentrations (r = 0.39). Published by Elsevier Ltd.
