Although background concentrations are provided by stationary pollen monitoring stations, they do not accurately reflect personal exposure. Knowing personal exposure makes it possible to establish a link between inhaled pollen grains and symptoms. Characterizing personal exposure to pollen using portable devices is challenging and requires time-consuming visual counting of pollen grains. We have developed a method for counting sedimented BPGs based on easy sampling using a handheld hoover and automated analysis by gas chromatography-mass spectrometry (GC-MS). This work is a feasibility study on the use of a lipid tracer (heptacosane) for the mass quantification of sedimented BPGs in outdoor and indoor environments. Before a lipid tracer could be used for the determination of BPGs, we ensured that the variability of total lipid mass was low (around 17%) for pollen samples from various geographical origins and for several pollen seasons. The limit of quantification of sedimented BPGs by GC-MS was estimated to be 100 µg (equivalent to 16,000 BPGs), i.e. about 1.6 BPG cm⁻² for a sampled surface of 1 m². This method of assessing individual exposure was implemented during the birch pollen season indoors (between 70 and 225 sedimented BPGs per cm²) and outdoors, directly on the ground under a birch tree (over 6600 BPGs per cm²). This method of counting sedimented pollen grains is suitable for large sample series, and the data obtained could be used as an indicator of individual exposure to indoor air pollen in a large number of patients as part of epidemiological surveys.</p></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"41 2","pages":"333 - 344"},"PeriodicalIF":2.1,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145165754","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}

Wind-dispersed (anemophilous) pollen is not only crucial for plant reproduction but also a prominent trigger for allergic diseases affecting a large portion of the global population. We analyzed atmospheric pollen concentrations alongside meteorological variables to assess the timing, duration, and intensity of pollen seasons in both locations over the period 1998–2023. Results indicate that birch pollen seasons are more sensitive to meteorological factors, including temperature and precipitation, than grass pollen seasons. In Akureyri, both birch and grass pollen seasons demonstrate greater responsiveness to environmental changes, with complex interactions involving preceding weather conditions. In contrast, Kraków exhibits a more stable climate, with clearer correlations between meteorological variables and pollen production. This comparative analysis reveals that while Kraków grass pollen seasons are predominantly influenced by temperature, Akureyri dynamic weather leads to more variability in pollen season characteristics. Understanding these differences is essential for predicting future changes in pollen exposure and their implications for public health, particularly in light of climate change. Our findings emphasize the need for localized research to unravel the intricate relationships between geographic location, climate variability, and pollen season characteristics, providing valuable insights for managing allergic diseases related to pollen exposure.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"41 2","pages":"269 - 287"},"PeriodicalIF":2.1,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163327","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}

The monitoring plan considers the evaluation of 0.5 µm or greater PM, the total microbial load and yeasts and molds from air and surfaces in areas close to the construction site, which are categorized in very high risk (VHR), high risk (HR), and medium risk (MR). Conformity rates for each parameter were assessed from September 2021 to September 2022. Conformity rates for both air and surfaces decrease proportionally with the environmental cleanliness, with the highest levels observed in VHR–HR (83% for air and 100% for surfaces) and the lowest in MR (38% for air and 88% for surfaces). Considering the PM, the lowest conformity rate is observed in VHR (43%), while the highest rate is recorded in MR (83%). Conformity rates decrease during the warmer months. The effectiveness of preventive and protective measures, such as weatherstripping and enhanced sanitation of both indoor environments and air handling systems (which can be assessed through environmental monitoring) is an effective strategy for mitigating infectious risks throughout the construction process.

The present study gave insights about prevalence of allergens (bacterial and fungal) in straw dust. The study, conducted during 2023 at PMAS Arid Agriculture University Rawalpindi, Pakistan, aimed to evaluate reduction of pathogens frequency through three newly developed dust control systems, viz. system-I (dust control chamber), system-II (cyclone separator), and system-III (misting) attached to wheat thresher and control (conventional wheat threshing). Airborne pathogens (fungal and bacterial) were sampled using Petri plates placed at different distances from wheat thresher’s outlet using each dust control system as well as conventional wheat threshing. Bacterial and fungal colonies were cultured, isolated and noted their frequency. Four fungal genera (<i>Aspergillus sp., Cladosporium sp., Alternaria sp.</i> and <i>Penicillium sp.</i>) were identified from straw dust based on morphological characteristics. The prevalence of <i>Cladosporium sp.</i> was generally higher compared to other genera. Frequency of bacterial and fungal colonies decreased as the distance from the wheat thresher increased. Mean pathogen frequencies of bacteria (15, 17, 18 and 18) and fungi (32, 40, 48 and 184) were recorded for system-I, system-II, system-III and control, respectively. Results revealed that frequency of fungal pathogens was higher than bacterial in straw dust in all treatments. Percent decrease in bacteria (16.7, 5.6 and 0) and fungi (82.6, 78.3 and 73.9) was found for system-I, system-II and system-III, respectively. Hence, it can be inferred from results that system-I (dust control chamber) can reduce pathogens frequency effectively.

The reference dataset was derived from the pollen transport model SILAM (System for Integrated modeling of Atmospheric composition) using ECMWF ERA5 meteorology and pollen emission sources specific for Belgium. Secondly, for evaluating the network coverage representativeness, we perform a footprint-based analysis by running SILAM in the backward mode for the same seasons, which indicates the areas contributing to the concentrations observed in each station. We show that the Belgian aerobiological surveillance network performs well with respect to the spatiotemporal reference dataset for airborne birch and grass pollen near the surface. The quality threshold (normalized RMSE) is met in 79% of the birch pollen days and 80% of the grass pollen days over the nine pollen seasons.
