The objective of this study was to provide a comprehensive assessment of the estimated total fungal DNA concentration of airborne fungi in Las Vegas using polymerase chain reaction (PCR) across different seasons, weather patterns, and meteorologic factors. Environmental air samples collected for one year from 13 sites across Las Vegas were analyzed with a universal fungal PCR assay. Standards of known concentration were used to determine DNA copies in the samples. The estimated total fungal DNA concentration ranged from 346 to 4967 copies/m³. The mean estimated total fungal DNA concentration was 2276 copies/m³. There was a significant difference in the mean estimated total fungal DNA concentration between seasons (<i>p</i> = 0.026). There were no significant correlations between estimated total fungal DNA concentration and meteorologic factors. This study utilized a molecular detection method to measure outdoor fungal DNA concentrations. The methodology developed in this study can enhance indoor and outdoor air quality surveillance for public health assessment by providing rapid and quantitative results.</p></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"42 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10453-026-09905-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147342627","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}

In Australia, the considerable prevalence of allergic rhinitis (23.8%) and asthma (11%) is creating a major health and economic burden. Subtropical grass species exhibit distinct ecological and phylogenetic differences compared with temperate grasses, including variations in pollen allergen composition and immune response. Traditional light microscopy, however, cannot differentiate between airborne grass pollen of various subfamilies. This study hypothesizes that automated holography and fluorometry sensing can discern grass pollen beyond family level (Poaceae). This project applied automatic sensing to five aerosolized dried grass pollen samples from Panicoideae; <i>Paspalum notatum</i> (Bahia grass) and <i>Sorghum halepense</i> (Johnson grass), Chloridoideae; <i>Cynodon dactylon</i> (Bermuda grass), and Pooideae; <i>Lolium perenne</i> (Ryegrass) and <i>Phleum pratense</i> (Timothy grass). Datasets were examined for differences in distributions of holography-derived particle features and emitted fluorescence spectra. In three repeated measurement campaigns of the same dry <i>L. perenne</i> pollen sample, distributions of particle features, and relative fluorescence intensity values suggested that reliability and reproducibility of automatic sensors remain a challenge. Data from five grass pollen types, even within the same subfamily, showed distinct morphological and fluorescence profiles, particularly at excitation 280 nm with 357 nm emission. The automated monitoring was also capable of distinguishing dried and freshly collected local <i>P. notatum</i> pollen. To translate these new insights for improved respiratory disease management, further research with broader data collection and validation with key locally relevant pollen taxa will be required for more precise real-time monitoring of grass pollen exposure.</p></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"42 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10453-026-09902-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147339885","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}

Temperature influences the MPS start (MPSS), while rainfall affects the seasonal pollen integral (SPIn). Improving understanding of these relationships enables accurate pollen forecasts for allergy prevention, public health preparedness, and environmental health policies. The study investigates the impact of rainfall before pollen release using the Dry Days Since the Last Rain (DDSLR) method and defines the role of temperature, chilling, and forcing requirements in predicting the MPSS for <i>Quercus</i> and Cupressaceae in Córdoba (Spain) and Tulsa (Oklahoma, USA). Three approaches combining chilling and forcing heat thresholds were applied. All used Growing Degree Days (GDD°) to calculate forcing but differed in chilling calculation: chilling units based on defined thresholds, accumulative chilling temperature, and omitted chilling calculations altogether. The results show that <i>Quercus</i> MPSS occurred in mid-to-late March at both sites. Cupressaceae exhibited greater regional variation. DDSLR effectively predicted the main pollen season end (MPSE) in Córdoba and the SPIn of Cupressaceae in Tulsa (Oklahoma, USA), indicating regional differences in rainfall influence. The chilling threshold was 0 °C in both sites, while forcing thresholds varied by region and species. Methods excluding chilling showed better MPSS prediction. These findings highlight the value of rainfall and temperature in pollen forecasts.

Air samples were collected while aircraft were grounded, specifically from the cockpit and the central cabin aisle. Domestic and international flights were included, and analyses adhered to the Brazilian standard NBR 17037. Bioaerosols were sampled using a portable bioaerosol sampler.

This study investigated the impact of temperature, rainfall, and sunshine duration on pollen deposition from Japanese cedar trees at 109 monitoring stations across Japan between 1986 and 2023. We conducted regression analyses using monthly deviations of meteorological parameters with annual total pollen count and the first pollen deposition date as outcome variables. Our results indicate that higher summer temperatures are associated with increased pollen counts in the following year, whereas higher autumn temperatures are associated with reduced pollen counts.

In addition, higher winter rainfall was correlated with reduced pollen counts, and a longer sunshine duration during summer was associated with both an earlier onset and a larger amount of pollen deposition.
