Ozone and several polar volatile organic compounds (VOCs) including organic acids and carbonyls (aldehydes and ketones) were measured over an approximately 24 hour period in four residences during the winter of 1993 and in nine residences during the summer of 1993. All residences were in the greater Boston, Massachusetts area. The relation of the polar VOCs to the ozone concentration was examined. Indoor carbonyl concentrations were similar between the summer and winter, with the total mean winter concentration being 31.7 ppb and the total mean summer concentration being 36.6 ppb. However, the average air exchange rate was 0.9 hr-1 during the winter and 2.6 hr-1 during the summer. Therefore, the estimated carbonyl emission rates were significantly higher during the summer. Indoor organic acid concentrations were about twice as high during the summer as during the winter. For formic acid, the indoor winter mean was 9.8 ppb, and the summer indoor mean was 17.8 ppb. For acetic acid, the indoor winter mean was 15.5 ppb, and the summer indoor mean was 28.7 ppb. The concentrations of the polar VOCs were found to be significantly correlated with one another. Also, the emission rates of the polar VOCs were found to be correlated with both the environmental variables such as temperature and relative humidity and the ozone removal rate; however, it was difficult to apportion the relative effects of the environmental variables and the ozone removal.
1993年冬季，在四座住宅中，以及1993年夏季，在九座住宅中，对臭氧和几种极性挥发性有机化合物（VOCs）进行了大约24小时的测量。所有住宅均位于马萨诸塞州大波士顿地区。研究了极性VOCs与臭氧浓度之间的关系。夏季和冬季室内羰基浓度相似，冬季总平均浓度为31.7 ppb，夏季总平均浓度为36.6 ppb。然而，冬季平均空气交换率为0.9次/小时，夏季为2.6次/小时。因此，夏季羰基估计排放率显著更高。夏季室内有机酸浓度约为冬季的两倍。对于甲酸，室内冬季平均浓度为9.8 ppb，夏季室内平均浓度为17.8 ppb。对于乙酸，室内冬季平均浓度为15.5 ppb，夏季室内平均浓度为28.7 ppb。发现极性VOCs的浓度彼此显著相关。此外，还发现极性VOCs的排放率与温度和相对湿度等环境变量以及臭氧去除率相关；然而，很难区分环境变量和臭氧去除的相对影响。
