本研究的目的是确定空气污染对急性呼吸道疾病（ARI）的影响。在俄亥俄州阿克伦的两所学校，每天24小时监测空气污染物的水平。每个学校的孩子都完成了每日日记，作为检测ARI的筛选机制。一旦ARI被隔离，肺功能测试（PFT）运行在症状阶段;一旦孩子变得无症状，测试持续2周。本研究结果显示，SO2和NO2浓度在与工业界接壤的学校较高。每日日记的结果表明，在污染地区，咳嗽、流鼻涕和喉咙痛的发病率较高。肺功能测试表明，呼吸道在污染的学校受到更大程度的损害，如与基线相比，用力呼气量和最大呼气中段流量水平显著降低所示。最近的证据表明，儿童期ARI的频率和严重程度与成人期慢性阻塞性肺疾病有关。代替这些结果，它建议，在城市地区的二氧化硫和二氧化氮的水平应仔细考虑，因为它们涉及到急性亚临床综合征和慢性临床呼吸系统疾病。
The purpose of this study was to determine the effects of air pollution on acute respiratory illness (ARI). Levels of air pollutants were monitored on a daily 24-hour basis at two schools in Akron, Ohio. The children at each school completed daily diaries which served as a screening mechanism for detecting ARI. Once an ARI was isolated, pulmonary function tests (PFT) were run during the symptomatic phase; once the child became asymptomatic, tests were continued for 2 wk. The results of this study indicate that SO2 and NO2 levels are higher at the school that borders industry. Results of daily diaries indicate a higher incidence of symptoms-especially cough, runny nose, and sore throat-in the polluted area. Pulmonary function tests indicate that respiratory airways are being compromised to a much greater extent at the polluted school, as indicated by significantly reduced levels of forced expiratory volume and maximal midexpiratory flow as compared to baseline. Recent evidence suggests that frequency and severity of ARI in childhood are related to chronic obstructive lung disease as adults. In lieu of these findings, it is suggested that the levels of SO2 and NO2 in urban areas be carefully considered, as they relate to acute subclinical syndromes and chronic clinical respiratory disease.
