AB We studied variation in concentrations of airborne pollen and other particles of biologicalorigin in a boreal forest in Finland during 2003–2004. The highest concentrations of pollenwere observed in late spring and early summer, whereas the peak concentrations of otherparticles of biological origin (including e.g. fungal spores) occurred in August–September.Although the patterns in concentrations in 2003 and 2004 were similar, the concentrationlevels were significantly different between the years. The contribution of pollen and otherparticles of biological origin led to an increase in the measured particulate matter (PM)mass during the pollen season (mass of pollen and other particles of biological origin 5.9and 0.4 μg m–3, respectively, in respect to PMtotal mass of 9.9 μg m–3) but the effect ontotal particle number was negligible. The other particles of biological origin constituted thelargest fraction of measured primary biological aerosol particle (PBAP) numbers (~99%),whereas pollen showed a higher relative mass fraction (~97%) of PBAP. These resultsunderline the important contribution of PBAP to coarse atmospheric particle mass providingup to 65% of the total mass during the peak pollen season.
