“…Concentric ring graphs were generated, which represent the relative abundance (% of the total ring surface) of the main land uses and vegetation types surrounding the two pollen monitoring stations DEBIED and DEMUNC (0 to 1, 1 to 2, 2 to 5 and 5 to 10 km from the pollen trap). This spatial representation was used for interpreting the general landscape configuration that characterized the abundance of the main pollen sources for specific pollen types around the stations [3,32]. Further, the relative abundance spectrum of the all pollen types in the air was calculated for the period 2006-2016 using the 'iplot_abundance' function from the AeRobiology R package [35].…”

Land-Use and Height of Pollen Sampling Affect Pollen Exposure in Munich, Germany

Airborne pollen concentrations vary depending on the location of the pollen trap with respect to the pollen sources. Two Hirst-type pollen traps were analyzed within the city of Munich (Germany): one trap was located 2 m above ground level (AGL) and the other one at rooftop (35 m AGL), 4.2 km apart. In general, 1.4 ± 0.5 times higher pollen amounts were measured by the trap located at ground level, but this effect was less than expected considering the height difference between the traps. Pollen from woody trees such as Alnus, Betula, Corylus, Fraxinus, Picea, Pinus and Quercus showed a good agreement between the traps in terms of timing and intensity. Similar amounts of pollen were recorded in the two traps when pollen sources were more abundant outside of the city. In contrast, pollen concentrations from Cupressaceae/Taxaceae, Carpinus and Tilia were influenced by nearby pollen sources. The representativeness of both traps for herbaceous pollen depended on the dispersal capacity of the pollen grains, and in the case of Poaceae pollen, nearby pollen sources may influence the pollen content in the air. The timing of the pollen season was similar for both sites; however, the season for some pollen types ended later at ground level probably due to resuspension processes that would favor recirculation of pollen closer to ground level. We believe measurements from the higher station provides a picture of background pollen levels representative of a large area, to which local sources add additional and more variable pollen amounts.

“…• Australian research has demonstrated the potential of satellite remote sensing of grass seasonal greenness to augment forecast models of airborne grass pollen as a tool to reduce the health and socio-economic burden of pollen-sensitive allergic diseases. 51 • Australian research teams are using smartphone technology to publicly report measured airborne pollen levels, and as a means of symptom surveillance. Consistent with international calls for an approach to assessing, forecasting and communicating air quality that integrates the physical, chemical and biological components 52 , one Australian smartphone app (AirRater) tracks exposure to three key environmental hazards -temperature, air particles (PM 2.5 ) and aeroallergens.…”

Objectives: The impacts of climate change on allergens and allergic diseases are important and potentially serious in Australia. Australia is highly vulnerable to such impacts because of its very high prevalence of allergic diseases such as asthma and allergic rhinitis, and allergic sensitisation to environmental allergens such as certain pollens and fungal spores. This article aims to review published research on the impacts of climate change on allergens and allergic diseases from an Australian perspective. Methods: Research on climate change, allergens and allergy was reviewed. Recent global assessments of the topic were consulted, and supplemented with database searches to identify research published since the assessments were done, as well as research with an Australian focus. The databases used were Web of Science and Scopus. Only research published since the year 2000 was included. Results: The impacts of climate change on allergens and allergic diseases are many and varied. Impacts on pollen include effects on pollen production and atmospheric pollen concentration, pollen seasonality, pollen allergenicity, and the dispersion and spatial distribution of pollen. Similarly, there is evidence for effects on fungal spore production, seasonality and allergenicity. There are also likely effects on indoor moisture and mould growth. Beyond these respiratory allergens, climate change may also affect food allergens, stinging insect allergens and contact allergens. All these changes could affect allergic diseases, in particular allergic respiratory diseases such as allergic asthma and allergic rhinitis. Conclusions: A large and sophisticated body of research exists from which to gauge both current and potential future impacts of climate change on allergens and allergic diseases. However, most, if not all, of this is from outside Australia. Australian-focused research is therefore urgently needed. Australia's vulnerability to the adverse effects of climate change on allergic diseases is compounded by the precarious nature of aeroallergen monitoring, reporting and forecasting in this country. But Australia has an impressive wealth of relevant experience and expertise, and has the potential to address the challenge of both current and future impacts of climate change on allergens and allergic diseases.

“…The onset of the release of pollen from pasturelands depends on its growth phase, which can be estimated from space (Devadas et al 2018). The spatially varying timing and magnitude of the grass pollen season was modelled as a function of the satellite-derived enhanced vegetation index (EVI), a measure of the "greenness" of the landscape (Huete et al 2002; NASA 2020).…”
