Abstract
In this work study the seasonal behaviour of the conidia of Alternaria, as well as the main locations in the Castilla-La Mancha region where the levels of these conidia in the air may pose a risk of allergy for people who are sensitised to them. The study was conducted in 5 sampling stations belonging to the Castilla-La Mancha Aerobiological Network (Red Aerocam): Albacete, Ciudad Real, Cuenca, Guadalajara and Toledo, in 2008. The pollen traps and the sampling methodology used follow the guidelines of the Spanish Aerobiology Network (REA). Alternaria conidia are detected in the atmosphere of Castilla-La Mancha all year round, although the highest concentrations are obtained in May, June and July. The greatest annual concentrations are detected in the cities of Ciudad Real, Toledo y Guadalajara with 5.624 conidia, 4.527 conidia and 4.173 conidia respectively, followed by Albacete and Cuenca. Some locations sampled showed high maximum daily values on a considerable number of days: examples include the levels recorded in Ciudad Real on 20 March (722 conidia/m3), Toledo on 18 June (324 conidia/m3), and Guadalajara on 26 June (220 conidia/m3).
