title: [Croup syndrome and harmful agents in respiratory air. A statistical analysis of seasonal fluctuations of emission values in relation to the incidence of disease].
abstract: Between 1971 and 1983 admissions with croup syndrome to two hospitals for children were recorded. During this time 1926 patients were hospitalized in Mannheim and 661 patients in Darmstadt. Air pollution by SO2, NO2, NO, CO, O3 and dust were measured. In Darmstadt no correlation was found between croup and air pollution, while in Mannheim, monthly averages of SO2, NO2, NO and CO showed linear correlations with monthly cases of croup.
