对美国威斯康星州波蒂奇地区近 350 人的个人二氧化氮暴露量以及室内和室外浓度进行了测量。夏季，使用燃气灶的家庭中的浓度平均比室外水平高 18 .mu.g/m3（室内/室外比率中值 2.4），冬季高 36 .mu.g/m3（室内/室外比率中值 3.2）。对于拥有煤气炉（r = 0.85 夏季，r = 0.87 冬季）和电炉（r = 0.68 夏季，r = 0.61 冬季）的家庭，个人接触量与室内平均值密切相关；夏季，平均每天有超过 65% 的时间在家里度过，约 15% 的时间在户外度过，冬季则不到 5%。对于燃气炉组 (r = 0.20) 和电炉组 (r = 0.28)，冬季个人暴露与室外 NO2 水平之间的关联最弱。暴露和时间分配的测量表明，个人接触二氧化氮的情况存在很大的差异，根据烹饪燃料类型的简单分层可能无法充分解释这一变化。
Personal NO2 exposures and indoor and outdoor concentrations were measured for nearly 350 individuals in the Portage, WI [USA], area. Concentrations in homes with gas stoves averaged 18 .mu.g/m3 higher in the summer (median indoor/outdoor ratio 2.4) and 36 .mu.g/m3 (median indoor/outdoor ratio 3.2) higher in the winter than outdoor levels. Personal exposures were closely related to indoor averages for households with gas stoves (r = 0.85 summer, r = 0.87 winter) and with electric stoves (r = 0.68 summer, r = 0.61 winter); more than 65% of the average day was spent at home while about 15% was spent outdoors in summer and less than 5% in winter. The association between personal exposure and outdoor levels of NO2 was weakest during the winter for both gas (r = 0.20) and electric (r = 0.28) stove groups. The measures of exposure and time allocation indicate that there is a wide range of variability in personal exposures to NO2 that may not be adequately accounted for by simple stratifications based on cooking fuel type.
