Abstract
An aeropalynological study was carried out in the atmosphere of Munster, the largest city in the region of North Rhine-Westphalia (north-western Germany), based on the data obtained during a 3 year of air-monitoring study (2004–2006) using a Hirst-type volumetric pollen trap. During the studied period, a total of 34 pollen types were identified in the atmosphere of the city, 20 corresponding to woody taxa and 14 to herbaceous taxa. The mean annual pollen index was 34,737, although there were important fluctuations from year to year. March to August was the period when more than 95% of the annual total was collected. The 10 most abundant pollen types detected were Betula, Urticaceae, Taxus/Cupressaceae, Quercus, Alnus, Poaceae, Pinus, Fraxinus, Platanus and Fagus, in order of abundance, which, together, accounted for 89.15% of the total pollen. To better observe the overall dynamics of the different pollen types in the atmosphere of Munster, a pollen calendar was drawn up. This showed typical features of North European pollen calendars: a winter period with very little pollen, short intense seasonal periods, and a high representation of pollen types from species characteristic of mixed Mid-European and riverside forests, such as Alnus, Betula, Corylus, Fagus, Picea, Pinus, Populus, Salix, Fraxinus and Carpinus.
