The study revealed that <i>Cladosporium</i>, <i>Alternaria</i>, and <i>Coprinus</i> accounted for over 90% of the total fungal spores count. The relation to meteorology confirmed a distinction between “dry” and “wet” spores and their diurnal cycles, as <i>Ganoderma</i> and <i>Coprinus</i> peaked around dawn, and <i>Alternaria</i> and <i>Cladosporium</i> peaks correlated with daily peaks of temperature and relative humidity. Automatically quantified daily concentrations of total airborne fungal spores showed a statistically significant positive correlation (Pearson r = 0.55, <i>p</i> &lt; 0.01) to values obtained from the manual Hirst method.

Here, we test whether pollen emissions from individual source plants can predict spatial variation in airborne pollen at scales of hundreds of meters to kilometers. To do so, we quantified pollen release within a city for oaks (<i>Quercus</i>) by mapping individual trees using remote sensing, calculating each tree’s pollen production with allometric equations, and estimating the timing of flowering with satellite-derived temperature data. We also measured airborne pollen concentrations multiple times a week at 9 sites in the first year and at 15 sites in the second year. Predicted pollen release explained 86% of the spatial variation in measured airborne pollen across the pollen season and 55% of local airborne pollen concentrations on any given day, whereas a traditional monitoring station measurements explained only 34% of spatiotemporal variation. Airborne pollen was best predicted by pollen release within approximately 1–2 km. Our results demonstrate that airborne pollen can be effectively modeled within cities by quantifying pollen release from individual trees. This type of approach could potentially be applied elsewhere, improving predictions of airborne pollen within cities and providing opportunities to avoid allergen exposure, fine-tune medication use, and better inform tree management decisions.\u0000</p><h3>Graphical abstract</h3>\u0000 <div><figure><div><div><picture><source><img></source></picture></div></div></figure></div>\u0000 </div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"39 2","pages":"181 - 193"},"PeriodicalIF":2.0,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45703745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To avoid this problem, our study compared the variability of airflow rates of Hirst-type traps when using commercially-available low-resistance airflow meters (heat anemometers) at various timescales. Experiments were conducted in Munich (Germany) and Payerne (Switzerland), using 4 different easyFlux® instruments and 6 Hirst-type pollen traps. Measurements were taken on an hourly basis from dawn to dusk at both locations, and in addition at Payerne, weekly observations over a period of one year. When using the common hand-held rotameters (with airflow resistance) the flow was 28.3% lower than with resistance-free flowmeter (i.e., measured 10 L/min which was in reality 12.8 L/min). The coefficient of variation between the four easyFlux® devices ranged from 0.32% to 1.55% over one day and from 2.88% to 8.17% over an entire year. Some of the traps showed surprising flow variations during the day. Furthermore, flowrates deviated more when measurements were made at the point where the double-sided tape is behind the orifice than elsewhere on the drum. The measurements away from this point are representative of the flow rates for most of the period of operation and flow calibration should thus be carried out away from this point, contrary to the current procedure.</p></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"39 1","pages":"143 - 148"},"PeriodicalIF":2.0,"publicationDate":"2023-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10453-023-09782-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49644479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monitoring of aeroallergens in a city is usually limited to the use of a single trap for the whole area. While a single trap provides enough information on background pollen concentration for the area, varying pollen exposure across different urban environments, however, is not considered. In this study, we analysed aerobiological data of three pollen seasons (2017–2020) recorded with a volumetric pollen trap in Sydney, Australia. In order to assess spatial differences in pollen exposure across the city, we installed ten gravimetric traps recording pollen deposition for eight weeks during the summer of 2019/2020. We considered the influence of meteorological variables, land use, urbanisation and distance to the sea. Our results showed differences in pollen season characteristics across the three analysed seasons and correlations with meteorological parameters. Considering all years, we found for Poaceae and <i>Alternaria</i> the strongest positive correlation with mean temperature and for Myrtaceae and Cupressaceae with maximum temperature. Likewise, there were negative correlations with humidity (Myrtaceae, Cupressaceae, <i>Alternaria</i>) and precipitation (Myrtaceae, Cupressaceae). Days with medically relevant pollen and spore concentrations varied between years and we recorded the highest amount in 2017/2018 for Poaceae and <i>Alternaria</i> and in 2019/2020 for Myrtaceae. In addition, we found spatial and temporal variations of pollen deposition. However, we did not detect significant correlations between pollen deposition and land use, which can be attributable to drought conditions prior to the sampling campaign and the temporal setting in the pollen season. This study highlights the importance of continuous volumetric aerobiological monitoring as well as the assessment of pollen exposure at several locations across a large urban area.</p></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"39 1","pages":"149 - 168"},"PeriodicalIF":2.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10453-023-09783-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46939880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Predicting disease epidemics during the growing season remains a difficult challenge. To better understand the interaction between spore movement and disease epidemics, spore samplers were set up in Germany (two sites over 4 years), Poland (seven sites over 2 years) and the UK (two sites over 9 years), where the disease has been observed. Spore concentrations were determined using a real time PCR assay, and meteorological data were obtained from co-located automatic stations. Spore release events were seen to peak in June on mainland Europe and July in the UK. The pattern of spore release was broadly similar across countries with earlier peaks in mainland Europe. A relationship was observed in the UK between July spore levels and disease in following winter barley crops. Rainfall and temperature were proposed as significant drivers of spore release in these months. The major environmental parameter associated with spore release across the two UK sites was crop surface wetness, although some site-specific interactions were noted for rainfall and wind movement. Regression analysis of spore patterns and disease epidemics indicates a relationship between spore levels 75–105 days pre harvest and final disease levels in UK winter barley crops. This relationship was not observed in spring barley.
