“…The pollen season of Poaceae in Northern, Central and Eastern Europe lasts from the beginning of May to the end of July, while in Southern Europe -from April to June [18]. Similar season characteristics were observed in Szczecin, Poznań, Lublin, Szeged, Novi Sad and Zagreb [16,36,38,52].…”

“…In London, the most important factor was maximum temperature [33]. Other several studies found significant positive correlations between daily Poaceae pollen concentration and daily maximum temperature [31,34], daily mean temperature [35,36], and daily global solar flux [31,34]. Relative humidity and rainfall [35][36][37][38][39][40] had a negative effect.…”

Relative humidity and rainfall [35][36][37][38][39][40] had a negative effect. Many studies indicate some meteorological elements related to the start of Poaceae seasons: mean temperature in March-April (in the Netherlands), mean temperature before the season start (in Poland), total rainfall in July (in Australia), rainfall in June (in the Iberian Peninsula), cumulative temperature above 5.5°C in March-April, minimum temperature in the first decade of April and maximum temperature in the second decade of April (in the United Kingdom) [41][42][43][44][45][46].…”

“…In Poland, people sensitive to Poaceae pollen developed the first disease symptoms when exposed to more than 20 APG/m 3 [61]. In Croatia, Hungary and Serbia, the threshold value amounts to 30 APG/ m 3 [16,36], whereas in Spain the first allergy symptoms were observed at 25 APG/m 3 [62]. For children and adolescents from Malmö (Sweden), nose symptom scores increased continuously and linearly with pollen counts from concentrations of 0-30 APG/m 3 , wherefrom symptom severity [64] demonstrated that a concentration of 30 APG/m 3 was sufficient to induce symptoms in most grass-allergic asthmatics in Melbourne, Australia.…”

This paper presents the results of Poaceae pollen seasons from 2000-2010 in Timisoara, Romania. Airborne Poaceae pollen concentrations was high. An increasing trend in the annual totals was observed. The longest pollen season was recorded in the year 2000. The period in which the Poaceae pollen count exceeded the threshold value of 30 grains/m 3 lasted from 9 to 46 days. The present study analyzed the dynamics of pollen seasons in relation to meteorological factors. On the basis of Spearman's correlation test, the strongest positive correlation was found between the Poaceae pollen counts and temperature; and sunshine hours. Daily average relative humidity, atmospheric pressure and precipitation had a negative effect. A multiple regression analysis was applied to determine how much of the total variance in Poaceae pollen counts can be explained by meteorological parameters. The coefficient of determination ranged from 0.245 to 0.460. Our data illustrate the contrasting effects of temperature, wind, relative humidity and rainfall on the concentration of pollen in the air. The optimum conditions for Poaceae pollen release occur during late spring and early summer. The Poaceae pollen remains one of the major aeroallergens in Timisoara area.

“…Furthermore, strong associations of Ambrosia, Poaceae and Populus pollen counts with temperature and rainfall have been determined by several authors. Pollen counts were found to increase with temperature and decrease with rainfall for Ambrosia (Bartková-Ščevková, 2003;Makra et al, 2004;Peternel et al, 2006a;Piotrowska & WeryszkoChmielewska, 2006;Kasprzyk, 2008;Ščevková et al, 2010) and for Poaceae (Bartková-Ščevková, 2003;Peternel et al, 2006b;Ščevková et al, 2010). In a more detailed study, Makra et al (2011) found that an association measure is negative between the annual cycles of the daily slopes of Ambrosia and Poaceae pollen concentration trends on the one hand and the annual cycles of the daily slopes of mean temperature trends on the other hand.…”

Effect of meteorological parameters on Poaceae pollen in the atmosphere of Tetouan (NW Morocco)

et al. 2012

Poaceae pollen is one of the most prevalent aeroallergens causing allergenic reactions. The aim of this study was to characterise the grass pollen season in Tetouan during the years 2008-2010, to analyse the effect of some meteorological parameters on the incidence of the airborne Poaceae pollen, and to establish forecasting variables for daily pollen concentrations. Aerobiological sampling was undertaken over three seasons using the volumetric method. The pollen season started in April and showed the highest pollen index in May and June, when the maximum temperature ranged from 23 to 27 °C, respectively. The annual pollen score recorded varied from year to year between 2,588 and 5,404. The main pollen season lasted 114-173 days, with peak days occurring mainly in May; the highest concentration reached 308 pollen grains/m(3). Air temperature was the most important meteorological parameter and correlated positively to daily pollen concentration increase. An increase in relative humidity and precipitation was usually related to a decrease in airborne pollen content. External validation of the models performed using data from 2011 showed that Poaceae pollen concentration can be highly predicted (64.2-78.6 %) from the maximum temperature, its mean concentration for the same day in other years, and its concentration recorded on the previous day. Sensitive patients suffering allergy to Poaceae pollen are at moderate to highest risk of manifesting allergic symptoms to grass pollen over 33-42 days. The results obtained provide new information on the quantitative contribution of the Poaceae pollen to the airborne pollen of Tetouan and on its temporal distribution. Airborne pollen can be surveyed and forecast in order to warn the atopic population.
