    Abstract. Although beech (Fagus) pollen are often disregarded, they play an allergological role. This study focused on pollen season (PS) of European beech (Fagus sylvatica L.) and mean yearly temperatures (T) at two climatically different sites (lowlands vs. Alps) in Germany. Pollen sampling was conducted with 7-day recording volumetric spore traps between 1982 and 2014. Both PS parameters (start, peak, length, annual pollen index [PI]) and T were compared in two periods (1982–1991 and 1992–2014), and correlations between PS and T were analysed. At both sites, average PS occurred earlier in the second period. Statistically significant differences were proved at the alpine site in terms of start and peak of the season, and PI. On average, PS in the lowlands was shorter and occurred earlier than in the Alps. As is the case with a lot of temperate tree species, beeches show the masting phenomenon and PI differed greatly among the years. Mast years were much less frequent than non-mast years, and the differences between the pollen sums were significant. Average pollen counts at the alpine site were about three times higher than in the lowlands. At both sites, higher T was significantly correlated with an earlier start and peak of the season, and an increased PI. Trends of T over the years were significantly positive. Temperature increase as a part of climate change may contribute to an earlier occurrence of the flowering season of European beech and to higher airborne pollen concentrations.

  • Weather conditions and climate change have an effect on allergies
    Karl-Christian Bergmann
    Allergo Journal International (2016), DOI: 10.1007/s40629-016-0119-z
    Aerobiologia, 2016, DOI: 10.1007/s10453-016-9421-y
    Abstract. Climate change particularly affects the health of vulnerable groups, such as children, the elderly, and socially disadvantaged individuals. Asthmatics are also at greater risk from the results of climate change due to their non-specific and allergen-specific bronchial hyperreactivity. Climate change affects the production, release, and number of allergenic pollens throughout Europe. Tree pollen in particular is being seen earlier and in greater numbers, while little effect is seen on grass pollens, and mugwort pollen is showing a downward trend. The ragweed that is spreading throughout Europe is still only of regional relevance in Germany. Thunderstorm periods represent a risk for pollen asthmatics. Although little is known about changes in molds, an increase in mycelium growth and spore formation is anticipated. Warmer winters may result in changes to mite populations.

  • Intradiurnal patterns of allergenic airborne pollen near a city motorway in Berlin, Germany
    Aerobiologia (2015); DOI: 10.1007/s10453-015-9390-6
    A. Simoleit, U. Gauger, H.-G. Mücke, M. Werchan, B. Obstová, T. Zuberbier and K.-C. Bergmann

    Abstract.In this study, the seasonally averaged intradiurnal patterns of four different pollen types (Fraxinus, Betula, Poaceae and Artemisia) and the role of traffic volume, air pollution and selected weather parameters were investigated. Measurements were carried out with a 7-day recording volumetric spore trap (Hirst type) near a congested city motorway (the A 100) in Berlin, Germany, in 2012, 2013 and partly 2011. Both Poaceae and Artemisia pollen showed distinct patterns which were similar across the years. The main period of grass pollen concentrations in the air was from 8 a.m. to 10 p.m. with peaks about midday or in the afternoon. Mugwort pollen mainly occurred between 6 a.m. and 2 p.m. with a clear maximum from 8 to 10 a.m. With regard to Fraxinus and Betula pollen, the patterns were not as clear and showed differences throughout the years. The intradiurnal patterns of traffic volume and pollen load, mainly of Poaceae in the afternoon and Artemisia in the morning, were partly coincident. The combination of both a high pollen count and air pollution, due to exhaust emissions, represents a special health threat which could result in a double burden for allergy sufferers. In the case of the daily means of Betula and Poaceae, relative humidity had a significantly negative effect on pollen concentrations on the same and/or next day/s, sunshine duration (Poaceae) and air temperature (Artemisia) a positive one.

  • MACC regional multi-model ensemble simulations of birch pollen dispersion in Europe
    Atmos. Chem. Phys., 15, 8115–8130, 2015

    This paper presents the first ensemble modelling experiment in relation to birch pollen in Europe. The sevenmodel European ensemble of MACC-ENS, tested in trial simulations over the flowering season of 2010, was run through the flowering season of 2013. The simulations have
    been compared with observations in 11 countries, all members of the European Aeroallergen Network, for both individual models and the ensemble mean and median. It is shown that the models successfully reproduced the timing of the very late season of 2013, generally within a couple of days from the observed start of the season. The end of the season was generally predicted later than observed, by 5 days or more, which is a known feature of the source term used in the study. Absolute pollen concentrations during the season were somewhat underestimated in the southern part of the birch habitat. In the northern part of Europe, a recordlow pollen season was strongly overestimated by all models.
    The median of the multi-model ensemble demonstrated robust performance, successfully eliminating the impact of outliers, which was particularly useful since for most models this was the first experience of pollen forecasting.

  • Klimawandel und Pollenallergie: Wie können Städte und Kommunen allergene Pflanzen im öffentlichen Raum reduzieren?
    UMID 2 • 2015
    Karl-Christian Bergmann, Wolfgang Straff

    Zusammenfassung. Der Klimawandel führt zu Veränderungen der Pollenexposition der Bevölkerung. Besonders betroffen sind davon unter anderem Pollenallergiker, die auf Haselnuss, Erle und Birke reagieren, denn diese Bäume blühen früher im Jahr und produzieren Pollen in tendenziell höheren Konzentrationen. Dieser Trend verstärkt sich durch die Neuanpflanzung allergener Baumarten in Städten. Bisher gibt es in Deutschland keine Empfehlung zur Neupflanzung von Bäumen im öffentlichen Raum, die Rücksicht auf die Belange von Pollenallergikern nimmt. Vorgelegt wird hier ein Vorschlag, welche Baumarten bei Anpflanzungen in Städten zu vermeiden sind, um einer weiteren Erhöhung der Menge an Baumpollen gerade im Lebensraum vieler Menschen mit Allergien vorzubeugen. Beigefügt ist außerdem eine Auflistung allergologisch unbedenklicher Baumsorten, die aus diesem Grund zur Anpflanzung geeignet wären.

  • Risk of sensitization and allergy in Ragweed workers – a pilot study
    Brandt et al. Allergy, Asthma & Clinical Immunology 2014,10:42
    Oliver Brandt, Torsten Zuberbier and Karl-Christian Bergmann

    Abstract. Background:
    Due to its high allergenic potential Ambrosia artemisiifolia has become a health threat in many European countries during the last few decades. Hence, several cities and communities initiated ragweed eradication campaigns. In Berlin, Germany, so-called Ambrosia scouts are being assigned the task of finding and eliminating this weed. We sought to evaluate the potential risk of sensitization and allergy in these individuals.
    Findings: In order to assess the risk of sensitization and allergy, we followed-up 20 Ambrosia scouts by skin-prick test with inhalant allergens, immunoserological and pulmonary function tests. Additionally, medical conditions were evaluated by a questionnaire especially designed for this study. Despite close contact to ragweed over a median duration of 13.8 months, none of the participants became sensitized or allergic to ragweed. One individual developed a clinical non-relevant sensitization towards the taxiconomically-related plant mugwort. A decline in relative FEV1 was most probably due to heavy smoking.
    Conclusions: Our surprising findings suggest that intensive contact and exposure to high ragweed pollen concentrations do not necessarily result in sensitization and/or allergy, meaning that the allergenic potential of this weed might be lower than hitherto expected. However, it is also conceivable that continuous exposure to high allergen levels induced tolerance in the ragweed workers. Due to the relatively small number of subjects studied, our results might be biased and therefore investigations on larger study groups are needed.

  • Pollenflug in Deutschland 2011 und Veränderungen seit 2001
    Allergo Journal, 2013, DOI: 10.1007/s15007-013-0100-9
    M. Werchan, K.-C. Bergmann und H. Behrendt

    Seit 1983 werden in Deutschland durch die Stiftung Deutscher Polleninformationsdienst die allergologisch bedeutsamen Pollen gemessen. Dies sind die Pollen von Hasel, Erle, Birke, Gräsern, Roggen, Beifuß und (seit 2006) Ambrosia. In den letzten elf Jahren ist es zu geringen Veränderungen in der Menge dieser Pollen gekommen. Die Baumpollen treten tendenziell in steigenden Konzentrationen auf, Gräserpollen nehmen leicht ab, Roggenpollen sind in der Menge so gering, dass sie epidemiologisch bedeutungslos werden. Beifußpollen sind stark schwankend. Ambrosia nimmt – besonders regional – zu, löst aber bisher nur wenige primär ambrosiabedingte Allergien aus.

  • Verteilung von Pollen und Feinstaub in einem städtischen Ballungsraum am Beispiel der Großstadt Berlin
    Allergo Journal, 2013, DOI: 10.1007/s15007-013-0376-9
    K.-C. Bergmann, A. Simoleit, S. Wagener, H.-G. Mücke, M. Werchan and T. Zuberbier



    Die Studie beinhaltet Erkenntnisse zur Verteilung von Pollen und Feinstaub (Partikel < 10 μm; PM10) und deren möglicher Zusammenhang in einem großstädtischen Ballungsraum am Beispiel von Berlin.


    Im Mai und Juni 2011 wurden im Stadtgebiet für sechs Wochen parallele Messungen des Pollen- und PM10-Gehalts der Luft an drei verschiedenen Standorten mit unterschiedlichen Umgebungssituationen (innerstädtisch, vorstädtisch, verkehrsreich) durchgeführt.


    Sowohl für die Gräserpollen als auch für den Feinstaub wurden die höchsten Konzentrationen an dem verkehrsreichen Standort registriert. An allen Messstationen erreichten die Gräserpollenkonzentrationen an einigen Tagen die zur Auslösung allergischer Symptome erforderlichen Grenzwerte. Zwischen den Stationen ergaben sich für die Pollen- wie auch für die PM10-Konzentrationen gute Korrelationen. Ebenso konnte ein positiver Zusammenhang der jeweiligen Aufkommen mit den Tagesmaximaltemperaturen festgestellt werden. Schlussfolgerung: Die Konzentrationen von Gräserpollen an verschiedenen Plätzen innerhalb einer Stadt zeigen eine positive Korrelation, sie ist am höchsten an einem verkehrsreichen Standort. Höhere Temperaturen sind mit höheren Gräserpollenkonzentrationen verbunden.
