Abstract
Grasses' pollen produces allergens, which are the main cause of pollinosis in Poland and in many countries of Europe. In Poland the beginning of season falls in different days of May. Pollen monitoring was carried out in Lublin by volumetric method in years 2001-2004 by means of Lanzoni VPPS 2000 trap. Start of grass pollen season was marked by methods 98 % and ∑ 75 as well as by the Clot's method. Differences between them ranged from 1 to 7 days. The most approximate deadlines of beginning of pollen season were qualified according to methods 98 % and the Clot's one, except year 2002. It was defined the pollen season in Lublin begins between 5. and 21. of May. In that study impact of meteorological factors on the beginning dates of pollen seasons was estimated. It was stated statistically positive, essential correlation among the beginning of season and the daily mean, the minimum and maximum air temperature.
Highlights
Pollen allergy is a more and more frequently diagnosed chronic disease in persons at different ages
The statistical analysis used in this study showed a significant positive correlation with respect to grass pollen and air temperature
The grass pollen season determined by the 98% method starts in the conditions of Lublin in the first or second decade of May
Summary
Pollen allergy is a more and more frequently diagnosed chronic disease in persons at different ages. Air pollution and the so-called western style of living can be numbered among the most essential factors which favour the development of this disease condition (Liebhart , 2000). In Poland, over 90 % of persons who have pollinosis suffer due to grass pollen (O b t u 3 owicz et al, 1990). The grass pollen season is relatively long, and in the conditions of Poland it lasts about four months (Piotrowska and Weryszko - Chmielewska , 2004; P u c and P u c , 2004). Every year there are variations in the start and end dates of the season, as well. An attempt was made to assess the effect of selected weather conditions on the start dates of the grass pollen seasons in Lublin, and three methods of determination of pollen seasons over a period of four years were compared
