Sažetak
The aim of the study was to determine the onset, duration and termination of the ragweed pollen season ; intradiurnal, daily and monthly pollen variation ; and possible differences in the occurrence and concentration of ragweed pollen according to sampling site between 2002 and 2003. The study was conducted at three sampling sites in central Croatia over two pollen seasons (2002 and 2003) using the volumetric method of sampling (Hirst type sampler). In 2003, the ragweed pollen season was by 43% longer and the percentage proportion of ragweed pollen by 3.4% greater in comparison with 2002. The total ragweed pollen count and number of days with ragweed pollen concentration greater than 30 pollen grains per m3 air showed a declining tendency from East to West in both seasons. The intradiurnal peak concentration occurred between 10.00 a.m. and 2.00 p.m. The air concentration of ragweed pollen decreased with temperature decline and precipitation. Results of the study provided useful information to the individuals allergic to ragweed pollen, allowing them to adjust their outdoor activities so as to avoid contact with the allergen.
