Sažetak
Pollen from the grass family (Poaceae) is considered to be one of the most important aeroallergens in Europe. The objective of the present work was to analyze the dynamics of the grass pollen in the atmosphere of the city of Dubrovnik, southern Croatia, in the years 2005- 2009. The standardized aerobiological volumetric method of airborne pollen sampling was done by the Hirst sampler (Lanzoni VPSS 2000). The data were collected daily and are expressed in grains/m3 of air. In order to determine the relationship between the daily pollen counts and meteorological parameters Spearman correlation test was used. The length of grass pollen season during the study period was 160 ± 35 days. Grass pollen appears in the Dubrovnik atmosphere from the end of March until beginning of October. In the remaining months only single pollen grains could be detected in the air. The beginning of the main pollen season varied between March 25th and April 29th. The highest daily pollen concentrations were achieved from end of May until end of June, varying between 25 (in 2009) and 91 (in 2006 and 2007) pollen grains/m3. End dates of the grass pollen season varied from August 12th in 2007 to October 11th in 2006. The values recorded for total annual Poaceae pollen were extremely variable, ranging from 509 grains in 2009 to 1073 in 2006. The average annual pollen count obtained during the period studied was 791 pollen grains/ m3. Grass pollen grains represents only 4.4% of the annual pollen count, the highest proportion was recorded in 2005 (6.0%) and the lowest in 2009 (2.1%). Daily pollen concentrations present significantly positive correlation with temperature, negative with rainfall, and no significant correlation with humidity and wind speed. This study presents the first information about grass pollen season in the city of Dubrovnik which can be useful in the management of pollen related diseases.
