It is one of the major environmental and public health problems in many urban areas around the world. Intriguingly, recent evidences have unveiled the potential link between smog and antimicrobial resistance (AMR). Smog can contribute to AMR through a complex and multifaceted set of mechanisms, including particulate matter (PM) which is found in smog, mediated transport of AMR microorganisms and genes, disruption of the respiratory microbiome, and modulation of host immune responses. Since the PM can lodge deeper in the lungs and harbors antibiotic resistance genes (ARGs), it should be considered that PM contributes to AMR toward the respiratory tract infections and other infections. PM can create conditions conducive to bacterial survival and growth in the respiratory system due to inflammation and immune suppression. PM2. 5 and PM10 have been associated with several respiratory system ailments due to their capability to penetrate inner areas. Moreover, PM can serve as a carrier for ARGs and other microbial components, aiding in their spread. This interaction may accelerate the development and spread of AMR. It is imperative to further unleash the mechanisms adopted by microbial extracellular DNA associated with the PM to envisage the potential health and environmental hazards. eDNA, for example, has been shown to contribute to the diversity and composition of microbiota associated with PM, such as bacteria, fungi, and viruses. This review focuses on PM, ARGs, and microbial eDNA as emerging environmental contaminants. A comprehensive analysis is conducted of the mechanisms and circumstances that contribute to its spread in diverse settings. Considering the current explosive increase in microbial resistance to the antibiotics, this also necessitates uncovering the underpinnings of the smog’s effect on AMR and developing effective strategies for mitigating these deleterious smog effects on health and environment.</p></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"40 3","pages":"353 - 372"},"PeriodicalIF":2.2,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141885610","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}

Moreover, examination of the behavior of microorganism under these bio-relevant conditions and revealing the interaction between elements and pathogens is vital and necessary for deeper understanding. However, previous studies have ignored these topics. Therefore, the present study aimed to (i) investigate elements in household dusts extracted in simulated lung fluids, (ii) examine the total concentration of culturable bacteria and their biochemical responses with exposure to bio-fractions of household dusts, and (iii) assess their relations and risks using the model approaches by inhalation. Here, settled dusts were collected in 25 houses, and extracted in four simulated body fluids to determine bio-fractions of elements. Moreover, total count of potentially pathogenic and heterotrophic bacteria, and four clinically important culturable pathogens were incubated in the presence of household-dusts extracted in simulated body fluids. The activity, biofilm, biochemical and oxidative responses of pathogens were measured following household-dust exposures. Afterward, the relationship between elements and pathogen responses were evaluated, and model and derived approaches were used for risk assessments of elements and pathogens.

Currently, a couple of methods are available for pollen counting, such as manual counting, flow cytometry-based and image software-based counting. However, due to inconsistent results and experimental repeatability, a more accurate, consistent, and high-throughput quantification approach is required. This study evaluated and compared the performance between a proposed Swin-transformer-YOLOv5 (S-T-YOLOv5) and common YOLO models in pollen detection and quantification. The present study demonstrated that the S-T-YOLOv5 outperformed other YOLO models, including YOLOv3, YOLOv4, YOLOR, and YOLOv5 for alfalfa (<i>Medicago sativa</i> L.) pollen detection and quantification, with excellent precision (99.6%), recall (99.4%), F₁-score (0.995), <i>mAP50</i> (99.4%), and <i>mAP50-95</i> (76.2%) values. The <i>mAP50-95</i> (<i>mAP</i> at an IoU of 0.5–0.95) of S-T-YOLOv5 was 9.9, 58.7, 25.3 and 8.2% higher than those of YOLOv3, YOLOv4, YOLOR, and YOLOv5, respectively. Additionally, the S-T-YOLOv5 showed a good transferability in quantifying pollen with varied sizes and shapes in different plant species, including annual fleabane, camelina, Canadian goldenrod, Indian lettuce, mustard, and oilseed rape. In summary, our results showed that the S-T-YOLOv5 is an accurate, robust, and widely adaptable pollen quantification approach, with minimizing errors and labor expense. We would like to highlight the potential application of S-T-YOLOv5 in quantifying samples of airborne pollens from a known pollen source or insect-dispersed pollens (e.g., alfalfa) in supporting the environmental risk assessment of genetically engineered (GE) plants.</p></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"40 3","pages":"425 - 436"},"PeriodicalIF":2.2,"publicationDate":"2024-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141502242","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}

Leaf abscission from broadleaved trees and other perennial species can also indicate the status of plant health in response to climate. This happens primarily during autumn in response to seasonal growth conditions and environmental factors, such as changing photoperiod and reduced temperatures. During this period biological material is released in larger quantities to the environment. Here, rural bioaerosol composition during late summer and autumn was captured by MiSEQ sequencing of the rRNA internal transcribed spacer 2 (ITS2) region, a common marker for taxonomic variation. Meteorological parameters were recorded from a proximal weather station. The composition of atmospheric taxa demonstrated that deciduous tree DNA forms part of the bioaerosol community during autumn and, for several common broadleaved tree species, atmospheric DNA abundance correlated to high wind events. This suggests that both flowering and autumn storms cause bioaerosols from deciduous trees that can be detected with eDNA approaches.
