Aerobiología de la estación de palma de Mallorca (Islas Baleares): contenido y variación diaria del polen aéreo durante el periodo octubre 2003-diciembre 2004

Abstract

The airborne pollen from Palma of Majorca station (Balearic Island, Spain) during the period from October 2003 to December 2004 is analysed. The station is included in REA (Spanish Aerobiology Network) with the aim of supplementing and extending the knowledge of the city air plankton and increasing the pollen-counting station in insular place. The total amount of pollen grains was 21,267 pg/m3 showing that the highest pollen concentrations are found from March to June. The taxa with the highest airborne pollen inci­dence were: Parietaria, Urtica membranacea, Olea europaea, Platanus, Cupressaceae, Pinus, Poaceae, Plantago, Quercus spp. y Chenopodiaceae/Amaranthaceae. The diurnal variation of the taxa showed that, generally, the greatest pollen concentration is produced in the central diurnal hour. Despite this fact, some trees are present during the night too.
