Abstract

The present work analyzes the mains pollen taxas present in the atmosphere of Jaén city during the period 1999-2008, by using Hirst-type volumetric pollen trap. A total of 65.749 grains/m3 of air were recorded as average annual. The 97.6 % of the pollen spectrum is represented by 10 pollen taxa: Olea, Cupressaceae, Quercus, Platanus, Poaceae, Pinus, Urtica-Parietaria, Chenopodiacea/Amarantaceae, Plantago y Populus. The pollen taxa Olea (olive) is unquestionably the dominant in the Jaén atmosphere, with an average annual emission of 48.381 grains/m3 of air, that represent the 92.1 % of the total, being the city were are registered the highest concentrations of this allergenic pollen. During march to june the highest concentrations of pollen are registered, being a critical period for the allergic population, since the majority are allergenic species responsible of spring allergy.
