The pollinic spectrum of the Madeira region is dominated by grass pollen, which also represents an important aeroallergen in Europe. The present work aims to analyze the main features of the Poaceae pollen season in the Madeira region to determine the allergic risk. The study took place in Funchal city, the capital of Madeira Island, over a period of 10 years (2003–2012). The airborne pollen monitoring was carried out with a Hirst type volumetric trap, following well-established guidelines. In the atmosphere of Funchal, the mean annual Poaceae pollen index was 229. The mean Poaceae pollen season lasts 275 days, with an onset date in January/March and an end date in November/December. Poaceae counts showed a seasonal variation with 2 distinct peaks: a higher peak between March and June, and the second one in autumn. The peak values occurred mainly between April and June, and the highest peak was 93 grains/m3, detected on the 27th May of 2010. The Poaceae pollen remaining at low levels during the whole growing season, presenting a nil to low allergenic risk during most of the study period. Higher critical levels of allergens have been revealed after 2006. In general, the pollen risk from Poaceae lasted only a few days per year, despite the very long pollen season and the abundance of grasses in the landscape of Madeira Island.

Pyłek traw stanowi jeden z głównych aeroalergenów w Europie. W pracy analizowano główne cechy sezonu pyłkowego Poaceae w powietrzu miasta Funchal, stolicy wyspy Madera (Portugalia). Monitoring pyłku prowadzono zgodnie z ustalonymi wytycznymi przy użyciu aparatu wolumetrycznego typu Hirsta, przez okres 10 lat (2003–2012). W okresie badań średnia roczna suma pyłku Poaceae wynosiła 229. Średnia długość sezonu pyłkowego Poaceae trwała 275 dni; początek sezonu przypada w styczniu/marcu, a koniec w listopadzie/grudniu. Stężenie pyłku Poaceae wykazywało zmienność sezonową, z dwoma wyraźnymi maksymami: wiosennym (marzec/czerwiec) oraz jesiennym (październik/listopad). Maksymalne stężenie wynoszące 93 ziaren/m3 zanotowano 27 maja 2010 roku. Główny sezon pyłkowy Poaceae występuje wiosną, jednak przez większą część okresu badań pyłek Poaceae wykazywał niskie stężenie w ciągu całego okresu wegetacji, stwarzając zerowe lub niskie zagrożenie alergenne. Wyższe krytyczne wartości stężeń pyłku Poaceae zaobserwowano po roku 2006. Pomimo licznych zbiorowisk ruderalnych z przewagą traw w krajobrazie wyspy oraz bardzo długiego sezonu pyłkowego, zagrożenie pyłkiem Poaceae dla osób wrażliwych trwało jedynie kilka dni w ciągu roku.
