Traduction en anglais : Indicator components of the outdoor pollution in Leipzig.
Between January and December 1994, the outdoor air quality of the city of Leipzig, Germany, was examined at 13 kindergardens.
SO2, CO, NOx, O3, total suspended particles, sedimentation dust and volatile organic compounds were measured.
Although each monitoring site appears to have its own individual pollutant profile, two general pollution profiles could be identified as to Leipzig using principal component analysis.
These profiles are largely attributable to two dominant emission sources, domestic heating and traffic.
Indicator components were identified for both pollution profiles.
Benzene was found to be the indicator component for traffic and SO2 for domestic heating.
The predominating types of pollution are reflected in the prevalences of respiratory diseases among 519 children investigated based on parent-completed questionnaires.
High traffic pollution was found to be associated with an increased occurrence of asthma and allergies and domestic heating with bronchitis.
