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%). These findings provide observational evidence of seasonal, multi-pollutant environmental associations with allergic respiratory disease burdens in a tropical urban setting, which points to the importance of integrated bioaerosol and air quality monitoring and gender-disaggregated health surveillance.</p></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"42 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189122","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 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. Here, for adjusting the timing, a phenological calendar method was used.</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":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10453-026-09946-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149189234","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}

Annual sums of spore concentrations ranged between 2116 and 5323, exhibiting a negative trend (R = − 0.6).

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.

Data from six Spanish cities, grouped into central and southeastern regions, were analysed for eight pollen taxa, total pollen, and multiple meteorological variables using standardised monitoring methods and percentile-based classification. The results revealed clear regional contrasts: central Spain experienced higher pollen concentrations, especially from arboreal taxa such as Cupressaceae and <i>Platanus</i>, whereas southeastern Spain was dominated by herbaceous pollen, particularly Amaranthaceae. Extreme pollen events were more frequent and intense in central Spain. Abrupt increases in temperature were generally associated with higher pollen concentrations, particularly for <i>Olea</i>, Poaceae, Urticaceae and <i>Platanus</i>. In contrast, intense precipitation events were generally associated with reductions in arboreal pollen concentrations due to the washout effect of rainfall. Wind speed and relative humidity exerted pollen- and site-specific effects, notably sharp wind-driven increases in <i>Olea</i> pollen in Toledo. The findings highlight region- and taxa-specific sensitivities of pollen to weather variability, underscoring the need for localised public health and environmental management strategies.

This approach overcomes the limitations of simplified steady injection methods commonly used in previous studies. The RNG k–ε turbulence model was applied to simulate airflow. The discrete phase model was used to track particle transport. The selection of these models was supported by comprehensive validation against published data.

Compared to other ventilation schemes reporting a higher concentration of 1.0 × 10⁻⁴ kg/m³, the mixing ventilation scheme achieves a tenfold reduction. In contrast, displacement ventilation shows localized particle accumulation near the monitor, despite improved removal along the cough jet path.
