Rezumat:

During the past 5 years growing scientific interest in airborne ragweed pollen in relation to pollinosis has spread over Carpathian Basin.The ragweed pollen concentrations in the last five years (2000-2004) were studied in some cities, as Szeged, Pecs, Timisoara, Novi Sad, Zagreb and Ljubljana, within the framework of Euroregional Polleninformation Service. Some parameters of Ambrosia pollen, as annual sums of daily averages, maximum daily concentration per year, duration of pollen release of ragweed, number of days exceeding treshold value of clinical symptoms, were examined.
These pollen concentrations were very high in the 5 of studied cities, with the exception of Ljubljana. Annual peak days also were investigated. Ambrosia pollen number reached in the year of 2001: 1.125 pollen grains (PG) per cubic meter (m3) in Szeged, and 2.104 PG/m3 in Novi Sad, while its maximum was in Ljubljana only 387.
Duration of days when has been found ragweed pollen in air was between 44 days (Ljubljana) and 113 days (Novi Sad). The threshold value for clinical symptoms is considered to be 30 PG/m3. Number of days when the daily pollen count was higher than threshold value often reached 45-57 days/year in the some cities of euroregions.
