Abstract:

Against the background of the growing demand for indices suited to assess the integral air quality that is not restricted to a single air pollutant, formulations for statistical air stress indices and an impact-related air quality index (DAQx) are presented. Their sensitivity depending on emission and air mass exchange conditions is investigated by test calculations based on air pollution data from three different sites in southwest Germany characterised by different air pollution levels and one site (Szeged) in southern Hungary with a comparatively high air pollution level. The results can be explained by methodical characteristics of the indices and the local emission situation.

Vor dem Hintergrund der steigenden Nachfrage nach Indizes zur Bewertung der integralen Luftqualität, die über die standardmäBige Beurteilung einzelner Luftkomponenten hinausgeht, werden Ansätze für statistische Luftbelastungsindizes und einen wirkungsbezogenen Luftqualitätsindex (DAQx) vorgestellt. Ihre Sensitivität, die von den Emissionsbedingungen und den Austauschverhältnissen abhängt, wird über Testrechnungen für drei Standorte im Südwesten Deutschlands mit unterschiedlichem Emissionseinfluss und einen lufthygienisch belasteten Standort (Szeged) im Süden von Ungarn analysiert. Die Unterschiede in den Resultaten lassen sich über methodische Kennzeichen der berücksichtigten Indizes und die lokale Emissionssituation erklären.
