From November to May 1986 oscillatory resistance Ros was measured 6 times in 72 healthy persons in Cologne. Every person was examined at a fixed time of day, respiratory symptoms and bronchopulmonary diseases were considered. Seasonal fluctuations of resistance were found, with slightly elevated values in autumn and spring compared to the winter. Regression analysis showed a decrease of the mean and range of resistance with increasing height and a slight increase in smokers. There was no relation between the seasonal pattern of resistance and the air pollutants, as expected due to relatively low ambient concentrations. When in January 1987 ambient pollution increased, the investigation was repeated on Jan 21, 1987, the day with the highest concentration (daily average of SO2: 256 micrograms/m3). In February control investigations were performed. The resistance was significantly elevated in January 1987 compared to February 87 or to January 86. These results agree with those of other authors, who found a slight impairment of lung function in healthy persons when daily averages of SO2 concentrations exceeded 250 micrograms/m3. However, changes of the same or a greater extent may be caused by meteorological factors.
1986年11月至1987年5月期间，在科隆对72名健康人进行了6次振荡阻力（Ros）测量。每个人均在一天中的固定时间接受检查，并考虑了呼吸道症状和支气管肺部疾病。发现阻力存在季节性波动，秋季和春季的值比冬季略高。回归分析表明，随着身高增加，阻力的平均值和范围减小，吸烟者的阻力略有增加。正如由于环境浓度相对较低所预期的那样，阻力的季节性模式与空气污染物之间没有关系。1987年1月环境污染加剧时，于1987年1月21日（二氧化硫日平均浓度最高的那天，为256微克/立方米）重复进行了调查。2月进行了对照研究。与1987年2月或1986年1月相比，1987年1月的阻力显著升高。这些结果与其他作者的结果一致，其他作者发现，当二氧化硫浓度日平均值超过250微克/立方米时，健康人的肺功能会有轻微损害。然而，相同程度或更大程度的变化可能是由气象因素引起的。
