“…Recently, the indirect way of atmospheric pollutants leading to human health risks through simulating health-related microorganisms has been widely discovered. 89,97,98 AMPs could accelerate the transmission of pathogens and antibiotic resistance genes in indoor air. 29 Our results confirmed the size of ambient AMPs with environmentally realistic abundance was significantly correlated with the relative abundance of pathogenic gene families in the airborne bacterial community.…”

“…86,87 Sphingomonas can also produce molecules associated with human rapid airway hyperresponsiveness, such as α-galactosylceramide and glycolipid antigen PS-30. 84,88 Second, Sphingomonas are identified as a core taxon of airborne microbial community, 89 and could secrete extracellular polymeric substances to facilitate their colonization on solids including micropastics. 90,91 Despite the perceived toxicity of accumulated organic atmospheric pollutants on AMP surfaces for most microbes, 21 these pollutants might serve as nutrients for Sphingomonas due to their famous ability of degrading externally derived toxic compounds.…”

Microplastics are found in various human tissues and are considered harmful, raising concerns about human exposure to microplastics in the environment. Existing research has analyzed indoor and occupational scenarios, but long-term monitoring of ambient atmospheric microplastics (AMPs), especially in highly polluted urban regions, needs to be further investigated. This study estimated human environmental exposure to AMPs by considering inhalation, dust ingestion, and dermal exposure in three urban functional zones within a megacity. The annual exposure quantity was 7.37 × 10 4 items for children and 1.06 × 10 5 items for adults, comparable with the human microplastic consumption from food and water. Significant spatiotemporal differences were observed in the characteristics of AMPs that humans were exposed to, with wind speed and rainfall frequency mainly driving these changes. The annual human AMP exposure quantity in urban green land spaces, which were recognized as relatively low polluted zones, was comparable with that in public service zones and residential zones. Notably, significant positive correlations between the AMP characteristics and the pathogenicity of the airborne bacterial community were discovered. AMP size and immune-mediated disease risks brought by atmospheric microbes showed the most significant relationship, where Sphingomonas might act as the potential key mediator.

“…The profound impact of bioaerosols on public health and safety is a major concern, − as they essentially contain pathogenic active components that are adverse to the health of people all over the world considering that they can migrate and be transported everywhere through the persistent moving air mass in a wide scale. Especially when the aerodynamic diameter is less than 5 μm, the microorganism bioaerosols can readily enter the human body, , which further raises a range of allergic, pathogenic, and reactive diseases such as COVID-19 (coronavirus), varicella (herpes zoster virus), tuberculosis ( Mycobacterium tuberculosis ), etc.…”

Bioaerosols pose a great threat to human life and health, and developing highly efficient and accurate identification and analysis methodologies for bioaerosols provides prerequisite knowledge to evaluate their toxicity on human health. In this paper, a rapid and economical method is proposed for the detection of bioaerosols based on surface-enhanced Raman scattering (SERS). The SERS substrate was prepared using an anodic aluminum oxide (AAO) template with an inverted conical (V-shaped) nanopore array structure that was subsequently deposited with Ag nanoparticles (AgNPs) through magnetron sputtering. This tailored nanostructure essentially enables the differentiated and efficient detection of Escherichia coli and Staphylococcus epidermidis health risks within 10 min, along with corresponding detection limits of 10 3 cells/mL and 10 4 cells/mL, respectively. Notably, by comparing the Raman spectrum of the two bacteria obtained from the plain plane deposited with the same AgNPs, the V-shaped nanopore array structure provides a more robust enhancement effect in the Raman signal relative to the ordinary plane. More importantly, the applicability of developed AgNPs@V-shaped AAO SERS substrate was validated using ambient bioaerosols, thus emphasizing the great potential of the application of SERS-based technique for a cost-effective, rapid label-free and culture-free bioaerosol analysis without experiencing conventional time-consuming and laborious incubation processes.
