The Pollution Effects on Asthmatic Children in Europe (PEACE) study examined the acute effects of short-term changes in air pollution on symptomatic children. We were one of 14 research centres in Europe that used a common study protocol. Seventy five children in an urban panel and 72 children in a control panel, selected with a screening questionnaire, were characterized with lung function tests and skin-prick tests and followed in a 12 week diary study. Identical air quality monitoring stations were set up in our two study areas. The levels and ranges in concentrations for all air pollution indices were small. A negative correlation was seen between time spent outdoors and pollution levels, which may have weakened the correlation between personal exposure and outdoor concentrations and obscured any effect of air pollution. No consistent pattern of relations between air pollution and adverse effects were found, but particulates and nitrogen dioxide tended to be associated with a nonsignificant increase in symptoms and medication use on the same day. No clear effect of air pollution on respiratory health could be demonstrated.
