We assessed airborne bryophyte spores in the urban atmosphere of Bratislava (Slovakia) by combining long-term temporal monitoring with a spatial, land-use-based comparison, using complementary methods. Long-term variability was characterised from a ten-year rooftop dataset (2016–2025) collected with a Hirst-type volumetric trap. In 2025, ground-level occurrence was compared across four land-use types (urban core, garden, park, and peri-urban forest park) using personal volumetric samplers, combined with microscopy, cultivation with PCR-based identification, and Oxford Nanopore metabarcoding. Bryophyte spores occurred at consistently low concentrations and were detected sporadically. They were not recovered by metabarcoding, and cultivation yielded the green alga <i>Klebsormidium</i> sp. rather than any moss. Over the ten years, peak daily concentrations showed a significant increasing trend, whereas annual spore integrals rose weakly and non-significantly. Relative humidity was the most consistent environmental driver, with spore concentrations increasing under more humid conditions. In the ground-level samples, fungal spores dominated among the 54 recorded spore types, with <i>Cladosporium</i> most abundant, and the peri-urban forest park showed the highest type richness and concentrations. Metabarcoding confirmed a diverse community dominated by Ascomycota and Basidiomycota. The weak airborne bryophyte signal, evident across every method, reflects ecological constraints on spore production and release, although the relative contributions of ecological and methodological factors could not be fully disentangled. The contrast with the abundant, land-use-structured fungal community underscores how dispersal strategy shapes airborne presence. The study highlights the value of combining microscopy, cultivation, and molecular approaches when targeting low-abundance bioaerosol taxa.</p></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"42 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149338563","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}

Although local pollen sources are expected to strongly influence pedestrian-level exposure, the spatial relationship between pollen sources and measured pollen concentrations remains poorly understood. In particular, quantitative information on the effective dispersal distance of pollen grains remains limited, constraining the development of high-resolution pollen forecasts. We measured <i>Platanus</i> pollen concentrations at ground level (four sites) and at a rooftop reference site during the 2025 pollen season in Poznań, Poland. <i>Platanus</i> crown volume was estimated from airborne LiDAR data and integrated with wind conditions to calculate a daily pollen source strength index. Incremental buffer analysis (100–1600 m) was performed to identify the distance at which surrounding trees best explained local pollen concentrations. Pollen concentrations showed substantial spatial variability; however, no statistically significant differences were observed between co-located ground- and rooftop-level samplers. The strongest correlation between local pollen concentrations and surrounding pollen sources was observed within an 800 m radius (<i>r</i> = 0.406, <i>p</i> &lt; 0.001), whereas both smaller and larger buffer distances showed weaker relationships. These findings indicate that the effective influence distance of local <i>Platanus</i> pollen sources is approximately 800 m, suggesting that trees beyond this distance have only a limited influence on local pollen concentrations. Our findings provide an evidence-based parameter for source-area delineation in local pollen forecasting models and may support allergy management and urban tree planting strategies.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"42 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10453-026-09948-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149339565","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}

This study analysed temporal and spatial changes in pollen seasons in Estonia using aerobiological monitoring data from Tartu, Tallinn, and Pärnu. Temporal changes were assessed by comparing two monitoring periods in Tartu (1990–1998 and 2012–2022), while spatial differences were evaluated across stations in contrasting climatic settings. Annual mean air temperature in Tartu increased by 1.1 °C between the two study periods, with the strongest warming occurring in winter and early spring. The results demonstrate a clear advancement of flowering phenology in early-spring taxa. The 1st day of intensive birch (<i>Betula</i>) flowering advanced by approximately 4 days in Tartu, while alder (<i>Alnus</i>) flowering began substantially earlier in warm years, with the first intensive pollen episodes occurring up to 23 days earlier than during the 1990s. Inland Tartu consistently exhibited higher and longer-lasting pollen concentrations than the coastal sites of Tallinn and Pärnu. Statistical modelling showed that flowering onset can be predicted with moderate to very high accuracy using temperature-related variables. The best-performing models included mean temperature and daily degrees above 5 °C (DD5), while precipitation was not a significant predictor. Model prediction uncertainty ranged from 1 to 8 days depending on taxon. These findings highlight the need for updated pollen calendars and continuous aerobiological monitoring under ongoing climate warming.

This two-year longitudinal study in Ikorodu, Nigeria, examined the combined environmental associations of airborne bioaerosols and fine particulate matter (PM2.5) with allergic respiratory disease incidence. Using time-series analysis and Generalised Additive Models (GAMs) on a comprehensive dataset of environmental and clinical records, we found that monthly allergy case counts were associated with a bimodal seasonal structure: case counts co-occurred with elevated PM2.5 concentrations during the dry-season peak (December–January) and with elevated fungal spore deposition during the wet-season peak (June–August). Relative humidity was the sole statistically significant independent predictor (IRR = 0.921, 95% CI: 0.876–0.968, <i>p</i> = 0.001), with higher humidity associated with lower monthly case incidence. The Poisson GAM collectively explained 64.1% of deviance. A formally significant multiplicative interaction between bioaerosols and PM2.5 could not be established (Likelihood Ratio Test: <i>p</i> = 0.999); marginal prediction surfaces are therefore presented as exploratory visualisations only. Throughout the study period, we observed a consistent gender disparity, with female cases outnumbering male cases (61.3% vs. 37.9%).

To enable this prevention, a prediction of next day(s) pollen flight is needed. The most accurate predictions are from numerical models which calculate the expected airborne pollen concentrations using simulation of emission combined with atmospheric dispersal processes (as in the SILAM model). However, current numerical models are based on historical averages and make predictions for the whole of Europe, which is not always optimal for a specific location. In this study we adapted a continental numerical model forecast to regional conditions in two areas in Germany: Bavaria in the South, and Leipzig and Berlin in eastern Germany. Eleven automatic pollen monitors were continuously running in these areas, allowing predicted pollen concentrations to be compared with observations. Adaptation of the modelling process to a regional scale increased the correlation (r) between observations and predicted pollen flight by about 38% for birch (up to 0.71 ± 0.07) and 18% for grasses (up to 0.57 ± 0.09). The most effective optimised parameters for birch pollen were; (i) adjusting the grid from a rotated to a non-rotated Latitude–Longitude coordinate system; (ii) updating the distribution and abundance map of potential pollen sources; (iii) adjusting the rate of pollen released in a year; and (iv) the timing based on temperature sum for birch. For grass pollen, the same parameters were optimized, except for the temperature sum.

Results indicated that indoor and outdoor bacterial concentrations peaked in summer (3097 ± 354 and 2438 ± 566 CFU m⁻³) compared to winter (2131 ± 85 and 1534 ± 439 CFU m⁻³). Similarly, indoor and outdoor fungal aerosols showed higher summer concentrations (167 ± 60 and 205 ± 43 CFU m⁻³) than winter (54 ± 14 and 90 ± 39 CFU m⁻³). Size distribution analysis revealed that bacterial aerosols were predominantly associated with stage 3 (3.3–4.7 µm) in winter and summer. In contrast, fungal aerosols shifted from stage 5 (2.1–1.1 µm) in winter and stage 3 (3.3–4.7 µm) in summer. The highest respirable microbial load was calculated for adults during summer (13.0 ± 2.6 × 10³ CFU day⁻¹). Simulated respiratory dosimetry configurations demonstrated that child exposure models under nasal inhalation parameters yielded a 34–36% reduction in deep lung AL deposition compared to the oral breathing route.
