Institute Presentation

More than 30 years of experience and competence in outdoor air pollen monitoring and forecasting in combination with clinical impact. 20 years of experience in applied clinical trials. The Aerobiology unit at the ENT-Clinic of MUW is in close cooperation with the clinic’s allergy unit since 1976 and frequently also with the Institute for Pathophysiology of the MUW.  Numerous clinical trials have been performed, in particular also by making use of the Vienna Challenge Chamber (VCC) which was developed by us.

The main attention, however, is directed to the European Aeroallergen Network Database (EAN) which has been launched in 1988. It comprises daily pollen and spore counts from almost all European countries (except Bosnia, Montenegro, and the Caucasus Regions Moldavia, Georgia, Armenia, and Azerbaijan). Data reach back to 1974 in some cases, but due to the historical developments, most sites were added during the 1990ies or even later. About 400 sites out of a total of 700 are currently in operation.

An upgrade and reconstruction of the database allows now optionally the entry of bi-hourly values which will be used for the HIALINE verification procedures. This is essential for the data evaluation, because the change of the filters happens daily at 12:00 but daily pollen counts are reported from midnight to midnight or from 9 a.m to 9.am, respectively, in some sites. Two-hourly values allow a coordination of data values so that sampling from 12:00 to 12:00 can be brought into congruence with pollen values for the same time span. Daytime distribution patterns of various pollen types can vary a lot.

Pollen data will be available together with detailed meteo data for the participating centers. MUW will collect bi-hourly pollen data from the centers and meteo data from FMI for evaluation together with ELISA results. MUW aims to buy the high volume sampler equipment and actively take part in allergen sampling for Betula and Grass. The sampling equipment will be located next to the existing Hirst-type sampler on the roof of the Austrian Met Office in Vienna.
