Estudio comparativo en altura y distancia en el muestreo aerobiológico

Abstract

Atmospheric concentrations of pollen grains were studied in three different places at the University of Extremadura, in the city of Badajoz (SW Spain) between 2009 and 2012. Furthermore, airborne fungi were sampled on a weekly basis for two years using viable and non-viable sampling techniques, this was done with the Burkard spore traps and several portable samplers at 16 m height above ground level at the Faculty of Science. Fortysix pollen types were recorded with mean daily average pollen concentrations of 43 grains/m3 in winter and 349 grains/m3 in spring. In spring, 89% of the grains were represented by the pollen types Quercus, Poaceae, Olea, Plantago and Pinaceae and in decreasing order. In winter, Cupressaceae was the most common type. Statistically significant correlations were found between meteorological parameters and pollen concentration. In conclusion, a sampler can register pollen grains present in the air of a city like Badajoz, representatively, without underestimating the heterogeneous distribution of local flora. The fungi (spores and colonies) recorded on the terrace of the Faculty of Science were studied from the 25th March 2009 until 1st July 2011, using non-viable sampling with one Burkard spore trap and three different viable methodologies, two Burkard portable samplers with two types of inlet and one Sampl'air AESSixtyeight types of propagules and 80 taxa of fungal colonies were analysed. For non-viable and viable methods average total concentrations of 1942 spores/m3 and 340 CFU/m3 were registered. In conclusion, both types of sampler produced equivalent results and used together gave a more complete knowledge of the mycobiota in the air.
