Abstract. Bioaerosols play significant roles in causing health and climate effects. Sugar compounds air have been widely used to trace the source of bioaerosols. However, knowledge about association sugar molecules microbial community at taxonomic levels atmospheric aerosols remains limited. Here, compositions total suspended particles collected from a typical rural site, Gucheng, North China Plain were investigated by gas chromatography–mass spectrometry high-throughput gene sequencing, respectively. Results show that fungal structure exhibited distinct diurnal variation with largely enhanced contribution Basidiomycota night, while bacterial showed no obvious difference between daytime night. SourceTracker analysis revealed fungi bacteria mainly plant leaves unresolved sources (presumably human-related emissions and/or long-distance transport). All detected anhydrosugars alcohols trehalose variations lower concentrations higher which may be affected primary sugars (except trehalose) an opposite trend. Mantel's test more associations than structure. Co-occurrence strong few saprophytic genera low relative abundances, e.g., Hannaella, Lectera, Peniophora, Hydnophlebia, Sporobolomyces Cyphellophora. This study suggests entire community, rather specific taxa, likely greatly contributes aerosols, is

Microplastics are found in various human tissues and considered harmful, raising concerns about exposure to microplastics the environment. Existing research has analyzed indoor occupational scenarios, but long-term monitoring of ambient atmospheric (AMPs), especially highly polluted urban regions, needs be further investigated. This study estimated environmental AMPs by considering inhalation, dust ingestion, dermal three functional zones within a megacity. The annual quantity was 7.37 × 104 items for children 1.06 105 adults, comparable with microplastic consumption from food water. Significant spatiotemporal differences were observed characteristics that humans exposed to, wind speed rainfall frequency mainly driving these changes. AMP green land spaces, which recognized as relatively low zones, public service residential zones. Notably, significant positive correlations between pathogenicity airborne bacterial community discovered. size immune-mediated disease risks brought microbes showed most relationship, where Sphingomonas might act potential key mediator.

Offline techniques are adopted for studying air pollution health impacts, thus failing to provide in situ observations. Here, we have demonstrated their real-time monitoring by online analyzing an array of gaseous biomarkers from rats' exhaled breath using integrated sensor (IEBAS) developed. The include total volatile organic compounds (TVOC), CO2, CO, NO, H2S, H2O2, O2, and NH3. Specific breath-borne VOCs were also analyzed a gas chromatography-ion mobility spectrometer (GC-IMS). After real-life ambient exposures (2 h), the levels PM2.5 O3 both found significantly affect relative multiple breath. Eleven biomarkers, especially 1-propanol, detected as correlated with concentration, while heptanal was shown be O3. Likewise, significant changes rats under lab-controlled 150, 300, 1000 μg/m3 compared synthetic exposure. Importantly, experimentally confirmed reliable biomarker exposure, notable dose–response relationship. In contrast, conventional inflammation oxidative stress rat sera exhibited insignificant differences after 2 h exposures. results imply that can serve early sensitive indicator pollutant This work pioneered new research paradigm impacts obtaining important candidate information

Bioaerosols pose a great threat to human life and health, developing highly efficient accurate identification analysis methodologies for bioaerosols provides prerequisite knowledge evaluate their toxicity on health. In this paper, rapid economical method is proposed the detection of based surface-enhanced Raman scattering (SERS). The SERS substrate was prepared using an anodic aluminum oxide (AAO) template with inverted conical (V-shaped) nanopore array structure that subsequently deposited Ag nanoparticles (AgNPs) through magnetron sputtering. This tailored nanostructure essentially enables differentiated Escherichia coli Staphylococcus epidermidis health risks within 10 min, along corresponding limits 103 cells/mL 104 cells/mL, respectively. Notably, by comparing spectrum two bacteria obtained from plain plane same AgNPs, V-shaped more robust enhancement effect in signal relative ordinary plane. More importantly, applicability developed AgNPs@V-shaped AAO validated ambient bioaerosols, thus emphasizing potential application SERS-based technique cost-effective, label-free culture-free bioaerosol without experiencing conventional time-consuming laborious incubation processes.
