Abstract
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 ARl 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 mid-expiratory 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.
