Daily air pollution concentrations were extracted from the Aerometric Information Retrieval System database from the Environment Protection Agency in the USA. Mixed linear models and generalized estimating equation models were used to evaluate the effects of several air pollutants (ozone, sulphur dioxide (SO2), nitrogen dioxide (NO2) and particles with a 50\% cut-off aerodynamic diameter of 10 {\textmu}m (PM10) on peak expiratory flow rate (PEFR) and symptoms in 846 children with a history of asthma (ages 4{\textendash}9 yrs). None of the pollutants were associated with evening PEFR or symptom reports. Only ozone was associated with declines in morning \% PEFR (0.59\% decline (95\% confidence interval (CI) 0.13{\textendash}1.05\%) per interquartile range (IQR) increase in 5-day average ozone). In single pollutant models, each pollutant was associated with an increased incidence of morning symptoms: (odds ratio (OR)=1.16 (95\% CI 1.02{\textendash}1.30) per IQR increase in 4-day average ozone, OR=1.32 (95\% CI 1.03{\textendash}1.70) per IQR increase in 2-day average SO2, OR=1.48 (95\% CI 1.02{\textendash}2.16) per IQR increase in 6-day average NO2 and OR=1.26 (95\% CI 1.0{\textendash}1.59) per IQR increase in 2-day average PM10. This longitudinal analysis supports previous time-series findings that at levels below current USA air-quality standards, summer-air pollution is significantly related to symptoms and decreased pulmonary function among children with asthma.
