“…Atmospheric pollen concentrations differ greatly in time and space because they are dependent on local vegetation and weather conditions [3]. Moreover, biotic and abiotic particles from remote sources due to air mass movements add to the health burden through atmospheric transport [4,5]. Epidemiological studies investigate IgE mediated sensitization patterns in atopic individuals to reveal allergens of clinical importance, since sensitized individuals often develop symptoms of allergic disease.…”

“…In environmental terms, the local pollen spectrum depends on the natural vegetation, land use, ornamental flora in green urban spaces, and the ruderal urban flora (Werchan et al, 2018;Monroy-Colín et al, 2018;McInnes et al, 2017;Tosunoglu et al, 2015;Carinanos et al, 2014;Fernández-Rodríguez et al, 2014;Çeter et al, 2012), as well as on prevailing air currents (Alan et al, 2019;Rojo et al, 2015;Damialis et al, 2005). It can reveal the arrival of invasive plants, such as ragweed, when the presence of local sources is not yet known (Zemmer et al, 2012).…”

The duration and severity of the allergenic pollen season in Istanbul, and the role of meteorological factors

Information on the allergenic pollen season provides insight on the state of the environment of a region and facilitates allergy symptom management. We present a retrospective analysis of the duration and severity of the allergenic pollen season and the role of meteorological factors in Istanbul, Turkey. Aerobiological sampling from January 2013 to June 2016, pollen identification and counting followed current standard methodology. Pollen seasons were defined according to 95% of the Annual Pollen Integral (APIn) and the season start date was compared with the first day of 5 day consecutive non-zero records. Generalized additive models (GAMs) were created to study the effect of meteorological factors on flowering. The main pollen contributors were taxa of temperate and Mediterranean climates, and neophytic Ambrosia. Cupressaceae, Poaceae, Pinaceae, Quercus and Ambrosia had the greatest relative abundance. The pollen season defined on 95% of the APIn was adequate for our location with total APIns around 10.000 pollen*day*m−3. Woody taxa had generally shorter seasons than herbaceous taxa. In trees, we see precipitation as the main limiting factor for assimilate production prior to anthesis. A severe tree pollen season in 2016 suggests intense synchronous flowering across taxa and populations triggered by favourable water supply in the preceding year. GAM models can explain the effect of weather on pollen concentrations during anthesis. Under the climatic conditions over the study period, temperature had a negative effect on spring flowering trees, and a positive one on summer flowering weeds. Humidity, atmospheric pressure and precipitation had a negative effect on weeds. Our findings contribute to environmental and allergological knowledge in southern Europe and Turkey with relevancy in the assessment of impacts of climate change and the management of allergic disease.

“…AR and allergic asthma can be triggered by exposure to many different allergens, including those associated with plant pollen. A changing climate, increasing atmospheric carbon dioxide levels, the spread of exotic aeroallergenproducing species into new areas (Alan et al, 2020) and increasing geographic ranges of allergenic pollen taxa are all anticipated to increase pollen allergen exposure (Damialis et al, 2019), which will likely worsen the burden of these diseases in the future (Beggs, 2016). Thus, effective management and treatment of pollen allergy are a global health priority.…”

‘Pollen potency’: the relationship between atmospheric pollen counts and allergen exposure

et al. 2021

View full text Add to dashboard Cite

Pollen allergies are responsible for a considerable global public health burden, and understanding exposure is critical to addressing the health impacts. Atmospheric pollen counts are routinely used as a predictor of risk; however, immune responses are triggered by specific proteins known as allergens, which occur both within and on the surface of the pollen grain. The ratio between atmospheric pollen counts and allergen concentrations (‘pollen potency’) has been shown to be inconsistent, with potentially important implications for pollen monitoring practice. Despite this, there has been no previous synthesis of the literature and our understanding of the factors that influence pollen potency remains poor. We conducted a scoping review with the aim of deriving a current understanding of: (a) the factors that influence pollen potency; (b) its variation through time, between taxa and by location; and (c) the implications for pollen monitoring practice. Our synthesis found that pollen potency is highly variable within and between seasons, and between locations; however, much of this variability remains unexplained and has not been deeply investigated. We found no predictable pollen potency patterns relating to taxon, geography or time, and inconclusive evidence regarding possible driving factors. With respect to human health, the studies in our synthesis generally reported larger associations between atmospheric allergen loads and allergy symptoms than whole pollen counts. This suggests that pollen potency influences public health risk; however, the evidence base remains limited. Further research is needed to better understand both pollen potency variability and its implications for health.
