Polyethylene terephthalate (PET)-degrading bacteria in the pelagic deep-sea sediments of the Pacific Ocean
Environ Pollut. 2024 May 9:124131. doi: 10.1016/j.envpol.2024.124131. Online ahead of print.ABSTRACTPolyethylene terephthalate (PET) plastic pollution is widely found in deep-sea sediments. Despite being an international environmental issue, it remains unclear whether PET can be degraded through bioremediation in the deep sea. Pelagic sediments obtained from 19 sites across a wide geographic range in the Pacific Ocean were used to screen for bacteria with PET degrading potential. Bacterial consortia that could grow on PET as the sole carbon and energy source were found in 10 of the 19 sites. These bacterial consortia showe...

Investigating the temporal link between PM < sub > 2.5 < /sub > exposure and acceleration of Myocardial Ischemia Reperfusion Injury: Emphasizing the hazardous presence of metals in inhaled air
Environ Pollut. 2024 May 9:124113. doi: 10.1016/j.envpol.2024.124113. Online ahead of print.ABSTRACTExposure to PM2.5 is widely acknowledged to induce cardiotoxic effects, leading to decreased myocardial tolerance to revascularization procedures and subsequent ischemia reperfusion injury (IR). However, the temporal relationship between PM2.5 exposure and vulnerability to IR, along with the underlying mechanisms, remains unclear and is the focus of this study. Female Wistar rats were exposed to PM2.5 at a concentration of 250 μg/m³ for 3 hours daily over varying durations (7, 14, and 21 days), followed by IR induction. Ou...

Effects of chemical composition of ambient PM < sub > 2.5 < /sub > measured in Seoul on potential health risks and generation of reactive oxygen species
This study assesses the health effects associated with the chemical species of ambient particulate matter (PM) with an aerodynamic diameter ≤ 2.5 μm (PM2.5) in Seoul, focusing on identifying key chemical constituents and their sources. We employed two approaches to estimate health risks: (1) evaluating carcinogenic and noncarcinogenic risks using IRIS (Integrated Risk Information System) data from the US EPA (Environmental Protection Agency), and (2) quantifying the generation of hydroxyl radicals (·OH) following exposure to PM2.5 in surrogate lung fluid (SLF). Our results show a significant impact on human health from...

Electric field driven tourmaline/hematite dual mineral photocatalysis for efficient antibiotic removal
In this study, two directly mined natural minerals, tourmaline and hematite (TFO), were successfully combined. Characterization and experiments indicate that the pronounced enhancement of photocatalytic activity in Fe2O3 is attributed to the electric field effect on the surface of tourmaline. TFO successfully removes 93% of tetracycline (TC, 50 ppm) within 60 minutes. The reaction rate constant for TFO composite material (0.0410 min-1) is 8.5 times that of tourmaline (0.0048 min-1) and 14.1 times that of hematite (0.0029 min-1). Simultaneously, it markedly improves light absorption and charge carrier separation capabilitie...

Environ Pollut. 2024 May 8:124129. doi: 10.1016/j.envpol.2024.124129. Online ahead of print.ABSTRACTHuman-imported pollutants could induce water black, changing microbial community structure and function. Employed 16S rRNA high-throughput sequencing, field-scale investigations and laboratory-scale experiments were successively conducted to reveal mechanistic insights into microbial community assembly and succession of black-odor waters (BOWs). In the field-scale investigation, livestock breeding wastewater (56.7 ± 3.2%) was the most critical microbial source. Moreover, fermentation (27.1±4.4%) was found to be the dominan...

Diel Variations of Airborne Microbes and Antibiotic Resistance Genes in Response to Urban PM < sub > 2.5 < /sub > Chemical Properties During the Heating Season
This study explored the interactions between toxic components and microbial communities during the heating period to understand the variations in ARGs. Bacterial and fungal communities showed a higher susceptibility to diel variations in PM2.5 compared to their chemical properties. Mantel tests revealed that chemical properties and microbial community interactions contribute differently to ARG variations, both directly and indirectly, during circadian fluctuations. Our findings highlight that, during the daytime, the enrichment of pathogenic microorganisms and ARGs increases the risk of PM2.5 toxicity. Conversely, during t...

Regional impact assessment of air quality improvement: The air quality lifecourse assessment tool (AQ-LAT) for the West Midlands combined authority (WMCA)
Environ Pollut. 2024 Apr 29:123871. doi: 10.1016/j.envpol.2024.123871. Online ahead of print.ABSTRACTPoor air quality is the largest environmental health risk in England. In the West Midlands, UK, ∼2.9 million people are affected by air pollution with an average loss in life expectancy of up to 6 months. The 2021 Environment Act established a legal framework for local authorities in England to develop regional air quality plans, generating a policy need for predictive environmental impact assessment tools. In this context, we developed a novel Air Quality Lifecourse Assessment Tool (AQ-LAT) to estimate electoral ward-lev...

Atmospheric black carbon observations and its valley-mountain dynamics: Eastern Cordillera of the Central Andes of Peru
Environ Pollut. 2024 May 8:124089. doi: 10.1016/j.envpol.2024.124089. Online ahead of print.ABSTRACTGlacial bodies in the Peruvian Andes Mountains store and supply freshwater to hundreds of thousands of people in central Peru. Atmospheric black carbon (BC) is known to accelerate melting of snow and ice, in addition to contributing to air pollution and the health of people. Currently there is limited understanding on the sources and temporal variability of BC in valley and mountain environments in Peru. To address this problem, this study combined surface observations of BC collected during 2022-2023 with WRF model simulati...

Metabolite correlation permutation after mice acute exposure to PM < sub > 2.5 < /sub > : Holistic exploration of toxicometabolomics by network analysis
In this study, following a single intratracheal instillation of multiple doses (0, 25, and 150 μg as the control, low, and high dose), non-targeted metabolomics was employed to evaluate the metabolic impact of PM2.5 across multiple tissues. PM2.5 induced tissue-specific and dose-dependent disturbances of metabolites and their pathways. The remarkable increase of both intra- and inter-tissue correlations was observed, with emphasis on the metabolism connectivity among lung, spleen, and heart; the tissues' functional specificity has marked their toxic modes. Beyond the inter-status comparison of the metabolite fold-changes,...

PM < sub > 2.5 < /sub > -induced ferroptosis by Nrf2/Hmox1 signaling pathway led to inflammation in microglia
In this study, C57BL/6J mice were applied to evaluate the neurotoxicity of collected fine particulate matter (PM2.5), via oropharyngeal aspiration at two ambient equivalent concentrations. The Y-maze results showed that PM2.5 exposure in mice would lead to the damage in hippocampal-dependent working memory. In addition, cell neuroinflammation, microglial activation were detected in hippocampus of PM2.5-exposure mice. To confirm the underlying mechanism, the microarray assay was conducted to screen the differentially expressed genes (DEGs) in microglia after PM2.5 exposure, and the results indicated the enrichment of DEGs i...
