The aim of the study was to estimate the spore counts of Alternaria and Cladosporium using the single longitudinal traverse and twelve transverse traverses methods. Both the single and twelve traverses methods generally showed similar average daily concentration fluctuations of the two studied spore types on the same days, although the single traverse method usually presented higher spore concentrations. However, analysing the distribution of concentrations obtained using both methods, there were days when the single or twelve traverses method showed a rise or fall in concentration which was not reflected by the other method. In case of Cladosporium higher daily concentrations obtained using the twelve traverses method occurred more frequently in the months of the highest spore concentrations. The higher concentrations of Alternaria spores obtained using this method occurred more frequently in the months of the lowest concentrations. Analysis of correlation (Pearson’s correlation coefficient r) between those variables (number of days with higher concentration and monthly concentration) showed that the correlation was significant for Cladosporium and not significant for Alternaria, for both at the significance level alpha = 0.05. The results of the Wilcoxon’s Paired Sample Test indicated that for both taxa the average daily concentrations obtained using the 1 traverse method were significantly higher than those obtained using the 12 traverses method.

The aim of the study was to compare phenological observations of pollen seasons of selected early spring trees. Special attention was paid to meteorological conditions which favored or did not favor tree flowering and pollen release. For this reason, we used phenological observation, pollen counts, and meteorological data in five sites in the center of Kraków in the period 2009-2011. Phenological phases (5) of four tree species: Alnus glutinosa, Alnus incana, Corylus avellana, and Betula pendula, were analyzed. It was found that in case of A. glutinosa the pollen season often preceded the flowering period, while for A. incana those two phenomena were more correlated. As regards Corylus avellana, the beginning of the pollen season and phenological phases was simultaneous. However, pollen grains occurred in the air longer, even by a dozen or so days. The phenological phases and pollen seasons of Alnus and Corylus were dependent on meteorological conditions. To give the definition of the relationship between pollen concentration and weather conditions, Spearman rank correlation analysis was applied. High Alnus and Corylus pollen concentrations were found on sunny days with a maximum temperature over 10°C and no precipitation, and when the snow cover was gone. In case of Betula, the phenological phases of the full pollination period usually coincided with the periods of high pollen concentrations. However, Betula pollen sometimes appears earlier and stays in the air longer than the flowering period of local trees in the nearest vicinity. This situation indicates long-distance transport or secondary deposition.

The aim of the study was to evaluate pollen seasons of selected taxa with particular reference to allergic taxa such as birch (Betula sp.), grasses (Poaceae), mugwort (Artemisia sp.) in Cracow in 2003 and 2004 (project number 3 PO5D 034 24 funded by the State Committee for Scientific Research). Pollen concentrations obtained using the stationary Burkard trap and personal Partrap FA 52 were compared. The volumetric method was used in the study. Average daily concentrations (pollen grains × m-3) were obtained by counting pollen grains every hour along 4 longitudinal transects and applying an appropriate conversion factor. Duration of the pollen season was determined using the 95% method. Variations in annual totals of pollen grains (birch and mugwort), in start dates (especially for grasses) and in the season duration (birch and grasses) were found. The comparison of pollen concentrations obtained using the stationary and personal traps at the same place showed non statistically significant correlation for all the studied taxa and statistically significant correlations for birch, mugwort and grasses (Spearman rank correlation). However, the statistically significant differences between the concentrations obtained using Burkard and Partrap carried by patients (Wilcoxon's test) were noted. Very low concentrations of pollen grains measured indoor (work, flats) and the influence of the local plants growing in separate place (courtyard of the Allergology Department) on the pollen concentration were found.

The aim of the study was to compare the dynamics of pollen seasons of selected tree and shrub taxa among measurement sites in Kraków and its neighbourhood. The study was performed in Kraków and Piotrkowice Małe in 2002, as well as in Kraków and Giebułtów in 2006. During the study the volumetric method was applied and pollen grains were counted along four horizontal lines. The lowest percentage of Corylus pollen and the highest percentage of Betula pollen were found in the analysed sites. The differences among start dates in various measurement sites in a given year were inconsiderable. Statistically significant differences of SPI values for the majority of taxa were found between measurement sites and between seasons for Kraków. The pollen season dynamics showed one (Betula, Pinaceae) or more maximum values (Corylus, Populus, Fraxinus, Salix). The occurrence of many peaks could be explained by the appearance of several species within one genus in the studied area or by various weather conditions. In 2002 maximum pollen concentrations were recorded earlier than in 2006. The differences in these dates could be explained better by cumulative temperature >5°C than >0°C.
