Aerobiological study at Antequera (Málaga, Spain): 1998-1999

Abstract

In this work, an aerobiological study of the atmosphere of the city of Antequera (Malaga, southern Spain) has been carried out besides a pollen calendar, which have been made with tha data obtained during the two years studied (1998-1999). The sampling was made with the aid of a volumetric spore trap set up in the northerly area of the city. The pollen calendar only reflects taxa that showed a ten-days mean pollen concentrations equal to o greater than grain of pollen per cubic metre of air. Thirty three taxa were included in the pollen calendar, two of which (Oleo ettropaea and Cupressacene) represented almost 57% of the annual pollen counts. The greatest diversity of pollen types was detected during the spring time, February to June being when the highest concentrations were collected, period in which aproximatelly 93% of the annual pollen counts were recorded. Although important quantities of Urticaceae, Plantago and Chenopodiaceae-Amaranthaceae pollen were detected in April and May, during the period studied, several peaks were registered all over the year, which were basically due to the pollen of Cupressaceae, Platanus and Pinus in March; Quema in April, Oleo europaea in May and Poaceae in June. In addition, a high incidence of pollen coining from tree taxa was registered at Antequera sampling station since the most abundant pollen types were those from Oleo europaea, Cupressaceae, Quercus and Platanus.
