1988年冬季，作为人类环境暴露总量研究（THEES）的一部分，对PM-10的浓度进行了为期两周的测量。在新泽西州菲利普斯堡的一个小城市同时采集了室外和室内微环境的样本，并对非吸烟者进行了个人监测。有四个室外地点，八个室内地点和十四个戴着个人监视器的人。个人、室外和室内地点的平均浓度分别为66、48和42 μ g m-3，其中个人采样者的24小时平均值的8.8%高于150 μ g m-3。室外平均值相对于室内更高被怀疑与直径< 10 μ m的粗颗粒的更普遍的室外源以及对室内可吸入亚组分有贡献的住宅吸烟者的缺乏有关。在此期间，有一天，所有的室外场地超过24小时PM-10标准。室外水平的增加也反映在当天室内样本和个人样本的升高中。这可能是直接暴露在室外以及室外PM-10渗透到室内的结果。
The concentrations of PM-10 were measured for 2 weeks in the winter of 1988 as part of the Total Human Environmental Exposure Study (THEES). Samples were taken simultaneously in a small city, Phillipsburg, NJ for outdoor and indoor microenvironments, and with personal monitors on non-smokers. There were four outdoor sites, eight indoor sites and fourteen individuals wearing personal monitors. The mean concentrations were 66, 48 and 42 .mu.g m-3 for the personal, outdoor and indoor sites, respectively, with the personal samplers having 8.8% of the 24 h averages above 150 .mu.g m-3. The higher outdoor averages with respect to indoors were suspected to be related to more prevalent outdoor sources of coarse particles < 10 .mu.m in diameter, and the lack of residential smokers to contribute to the indoor respirable subfraction. There was one day during the period when all the outdoor sites exceeded the 24 h PM-10 standard. Increased outdoor levels were also reflected in elevated indoor samples and the personal samples on that day. These would be a result of direct outdoor exposures and the penetration of outdoor PM-10 to the indoors.
