[Correlation of respiratory tract symptoms in young children and NO2 concentrations of the outside air].
In four regions of Switzerland (2 towns, 1 municipal agglomerate, 1 rural area) the relationship between the degree of air pollution measured in terms of NO2 and the incidence of airway symptomatology was investigated in 1,225 young children. The airway symptoms were recorded by the parents in a diary; the NO2 loading was measured with the aid of personal collecting tubes at the place of residence of the child. A significant relationship was found to exist between the mean incidence of airway symptomatology per child and day, and the individually measured NO2 concentration in the outside air at the child's place of residence. This relationship remained significant even when, in a multiple regression analysis, account was also taken of other major factors, such as smoking, nationality, individual susceptibility to airway diseases, the season of the year, and the subjective assessment of the air pollution at the place of residence, were also taken into account.
