在空气污染发生之前、期间和之后，对 163 名小学生的肺功能进行了测量。事件期间，TSP、RSP 和 SO2 浓度均在 200-250 μg/m3 范围内，而在基线测量期间，它们通常低于 100 μg/m3。在此期间，肺功能与基线测量值相比显着降低了 3-5%。发病后 16 天仍观察到下降，但发病后 25 天则不再观察到下降。肺功能技术人员、肺功能测试设备以及基线和后续测量之间感冒患病率的差异无法解释这些发现。这些结果表明，持续几天的空气污染，24小时平均TSP、RSP和SO2浓度在200-250μg/m3范围内，与小学生肺功能下降有关。
Pulmonary function was measured in 163 primary school children before, during and after an air pollution episode. During the episode, TSP, RSP and SO2 concentrations were each in the range of 200-250 .mu.g/m3, whereas during the baseline measurements, they were generally below 100 .mu.g/m3. During the episode, pulmonary functions were significantly lower by 3-5 percent compared to the baseline measurements. The decline was still observed 16 days after the episode, but not 25 days after the episode. Differences in pulmonary function technician, pulmonary function test appliance and in the prevalence of colds between baseline and follow-up measurement, were not able to explain the findings. These results suggest that an air pollution episode of a few days, with 24-hour average TSP, RSP and SO2 concentrations in the range of 200-250 .mu.g/m3, was associated with a decrease in pulmonary function of primary school children.
