This study was carried out within the framework of the multicentre Pollution Effects on Asthmatic Children in Europe (PEACE) project. Two panels of mildly asthmatic children were studied. Seventy two children living in the Upper Silesia (the largest Polish industrial agglomeration) and 73 children in the control panel were followed up during two winter months in 1994. Ambient concentration of particles with a 50% cut-off aerodynamic diameter of 10 μm (PM10) black smoke, SO2 and NO2 were measured and peak respiratory flows and respiratory symptoms were recorded on a daily basis. There were no substantial differences in exposure to air pollution and the prevalence of respiratory symptoms between the urban and the control panels. No severe smog episodes were observed. No consistent association between daily changes of air pollution levels and daily variations of peak expiratory flows or respiratory symptoms prevalence and incidence was found. In conclusion, no clear effect of air pollution on respiratory health could be observed.
