Start dates, intensity and duration of Betulaceae, Oleaceae, Poaceae and Asteraceae pollen seasons were examined. Mean, slope of the regression, probability level (<italic>P</italic>) and dominant taxa (%) were calculated. Trends were considered significant at <italic>P <</italic> 0.05.</p> </sec> <sec id="all12419-sec-0004" sec-type="section"> <title>Results</title> <p>On a European scale, Betulaceae, in particular <italic>Betula</italic>, is the most dominant pollen exposure, two folds higher than to Poaceae, and greater than five folds higher than to Oleaceae and Asteraceae. Only in Reykjavik, Madrid and Derby was Poaceae the dominant pollen, as was Oleaceae in Thessaloniki. Weed pollen (Asteraceae) was never dominant, exposure accounted for >10% of total pollen exposure only in Siauliai (<italic>Artemisia</italic>) and Legnano (<italic>Ambrosia</italic>). Consistent trends towards changing intensity or duration of exposure were not observed, possibly with the exception of (not significant) decreased exposure to <italic>Artemisia</italic> and increased exposure to <italic>Ambrosia</italic>.</p> </sec> <sec id="all12419-sec-0005" sec-type="section"> <title>Conclusions</title> <p>This is the first comprehensive study quantifying exposure to the major allergenic pollen families Betulaceae, Oleaceae, Poaceae and Asteraceae across Europe. These data can now be used for studies into patterns of sensitization and allergy to pollen and foods.</p> </sec> </abstract>
