Sumario:[EN]Background: The determination of pollen types and their proportions in the atmosphere of relevant urban areas have increasingly been evaluated in different regions.The final goal has been to elaborate a pollen calendar, providing data about the occurrence of pollen grains in the air, thus permitting medical treatment and prophylaxis. Methods: An aerobiological study was carried out in the atmosphere of the city of Salamanca, Spain, during eight years (2000–2007) by means of a Hirst type volumetric spore trap.A pollen calendar was elaborated following exponential classes obtained from 10-day average concentrations of the main pollen types. Results: Mean annual pollen index was 16,916, coming from 72 different types of pollen. During the studied period, an increase of annual pollen levels was registered by means of regression analysis index.The most important types of pollen were Quercus, Poaceae, Cupressaceae, Olea, and Plantago. Arboreal pollen grains (62.7%) were more represented in airborne pollen spectrum than non-arboreal pollen (37.3%). Airborne pollen levels were particularly high between April and July, showing the highest values in May and June. Conclusions: In aerobiological terms Poaceae pollen seems to be a major risk for potential sensitised individuals due to its known allergenicity and its high atmospheric concentrations between late spring and early summer,followed by Cupressaceae, Olea and Platanus pollen grains, and taking into account the possible role of Fraxinus and Quercus in earl spring allergenic courses and in processes of cross-sensitivity, respectively.
