“…Precipitation, wind speed, and wind direction have an important role in the spreading and amount (concentration) of pollen in the air. However, temperatures higher than normal are able to improve pollen quantity and diffusion, frequently resulting in longer seasons of pollination in many plant species ([16,17,18,19]; see [20] for grasses). In this paper, we focus on this aspect and observe the trend of a long series of airborne pollen monitoring by considering the possible correspondence between pollen concentrations and variation of temperatures.…”

Aerobiological data have especially demonstrated that there is correlation between climate warming and the pollination season of plants. This paper focuses on airborne pollen monitoring of Betulaceae and Poaceae, two of the main plant groups with anemophilous pollen and allergenic proprieties in Northern Italy. The aim is to investigate plant responses to temperature variations by considering long-term pollen series. The 15-year aerobiological analysis is reported from the monitoring station of Vignola (located near Modena, in the Emilia-Romagna region) that had operated in the years 1990–2004 with a Hirst spore trap. The Yearly Pollen Index calculated for these two botanical families has shown contrasting trends in pollen production and release. These trends were well identifiable but fairly variable, depending on both meteorological variables and anthropogenic causes. Based on recent reference literature, we considered that some oscillations in pollen concentration could have been a main effect of temperature variability reflecting global warming. The duration of pollen seasons of Betulaceae and Poaceae, depending on the different species included in each family, has not unequivocally been determined. Phenological responses were particularly evident in Alnus and especially in Corylus as a general moving up of the end of pollination. The study shows that these trees can be affected by global warming more than other, more tolerant, plants. The research can be a contribution to the understanding of phenological plant responses to climate change and suggests that alder and hazelnut trees have to be taken into high consideration as sensible markers of plant responses to climate change.

“…These segments were mounted on slides with glycerin and basic fuchsin under coverslips. Pollen grains were counted along four longitudinal transects (using a light microscope at 400× magnification) (Cariñanos et al, 2000;Ianovici, 2015). Daily pollen concentrations are expressed as particles per cubic metre of ambient air (P/m 3 ).…”

The aim of the present study was to analyse the effect of weather conditions on Ambrosia artemisiifolia airpollen concentrations in the highly invaded area of western Romania. The investigation of Ambrosia pollen concentrations was carried out from 2000 to 2010 by means of the volumetric method. Ambrosia pollen concentrations had increasing trend over study period. The results of cluster analysis show that two main groups were identified: group A, with lower SPI (2000, 2001, 2002, 2003, 2004, 2007) and group B, with much higher SPI (2006, 2008, 2009, 2010). The statistical correlation between pollen concentrations and meteorological factors was determined by Pearson’s test. The relationships between Ambrosia pollen concentrations and meteorological parameters, were further assessed using multiple linear regression techniques. The pollen emissions are affected by meteorological factors in the main pollen season. Our results suggest that the abundance of Ambrosia artemisiifolia in western Romania is massive. The Ambrosia pollen load of Timisoara is most important between 15 August – 15 September. Consequently, this is the most dangerous period of the year for allergic reactions. The investigation of Ambrosia pollen behavior in the atmosphere is a compulsory step for measures to stop the spread and establishing control. Ambrosia pollen represents a major health problem and can be considered the main aeroallergenic plant pollen in our region.

The effect of geographical and climatic properties on grass pollen and Phl p 5 allergen release

The Poaceae family, including grasses, comprises several cosmopolitan and allergenic species. The aim of this study was to determine the correlations between Poaceae pollen and Phl p 5 allergen concentrations in two cities with different geographical and climatic properties in Turkey. Pollen were collected from Burkard traps in Ankara and Zonguldak. Phl p 5 sampling was carried out between March and October in both 2015 and 2016 using a BGI900 Cascade High Volume Air Sampler (900 L/min.). The concentrations of Phl p 5 were measured by the enzyme-linked immunosorbent assay (ELISA) technique. The annual sum of Poaceae pollen (pollen index) during 2015-2016 was 5454 in Ankara and 4142 in Zonguldak. The total Phl p 5 concentration was 1309 pg/m in Zonguldak, whereas it was 8181 pg/m in Ankara over 2 years. About 90% of the allergen was found in the fraction with particulate matter (PM) > 10 μm in both cities. It was found that the main meteorological parameter which affected pollen and Phl p 5 was temperature in both stations. Rainfall was also found to be important for Zonguldak, due to its climatic and geographic properties. Lastly, we suggest that the primary wind direction, which is from the south of Zonguldak, could have a 'drift effect' for allergens because of the airborne pollen concentrations and the dates on which the allergen is released into the atmosphere. The wind direction may be an important factor in the distribution of allergen and pollen grains in stations, especially those with a hilly topography.
