Pollen is an important source of allergens in the natural environment, and the cause of the appearance of symptoms of allergic disease in hypersensitive individuals. In our laboratory, we monitor 60 types of pollen of various allergenic potential, and publish the results of measurements from different phytogeographical areas in Slovenia. Data on daily concentrations, together with many years of experience, are the basis for making short-term forecasts about pollen air pollution.

Pollen calendar in Slovenian language is available here.
