Background/Objectives: Particulate matter (PM) is a primary health hazard associated with metabolic pathway disruption. Population characteristics, topography, sources, and PM components contribute to impacts. Methods: In this study, NMR-based metabolomics was used evaluate the impacts of prolonged exposure PM. Blood samples (n = 197) were collected from healthy volunteers in low- (control; CG) high-exposure areas (exposure; EG) Northern Thailand. Non-targeted metabolite analysis performed using proton nuclear magnetic resonance spectroscopy (1H-NMR). Results: Compared CG, EG showed significantly increased levels dopamine, N6-methyladenosine, 3-hydroxyproline, 5-carboxylcytosine, cytidine (p < 0.05), while biopterin, adenosine, L-Histidine, epinephrine, norepinephrine higher CG 0.05). These disturbances suggest that chronic particulate impairs energy amino acid metabolism enhancing oxidative stress, potentially contributing onset non-communicable diseases (NCDs) such as cancer neurodegenerative conditions. Conclusions: This study highlighted connection between sub-chronic PM2.5 exposure, disturbances, an risk (NCDs), stressing critical need for effective reduction strategies

Numerous studies linked fine particulate matter (PM2.5) to ischemic stroke. However, only a few investigated the differential associations with specific PM2.5 components and sources. We utilized electronic health records (EHR) from Mount Sinai Health System in New York City metropolitan area during 2011-2019 assessed of sources used mixed-effect Poisson survival regressions assess single-exposure chemical components. multivariable regression simultaneous source-apportioned exposures estimated using non-negative matrix factorization. Then, we sensitivity our results different specifications EHR data continuity: (1) less strict definition censorship year, (2) adjusting model for continuity index, validated algorithm measuring EHR-data based on indicators primary care service utilization. observed higher risks stroke (Risk ratio [95 % confidence intervals] per interquartile range increase) associated exposure nickel (1.080 [1.045; 1.116]), vanadium (1.070 [1.033; 1.109]), zinc (1.076 [1.031; 1.122]), nitrate (1.084 [1.039; 1.132]).

Abstract Street children, particularly those aged 3–8 years, may exhibit a pronounced vulnerability to environmental risk factors. This study investigated the exposure of street children ambient fine particulate matter (PM2.5) and noise at 30 major intersections in Tehran city, Iran. PM2.5 concentrations, levels, temperature, humidity, traffic conditions were measured. Health risks also assessed using hazard quotients (HQ) for different age groups, focusing on non-carcinogenic psychological effects. concentrations exceeded 15 µg/m3 all except one, with levels surpassing 40 key intersections. Noise consistently 70 dB, some 80 far above WHO guidelines 53 dB. analysis revealed HQ values over 2 years numerous intersections, indicating significant hazards. The emphasizes faced by Tehran, revealing that elevated concentration pose health threats. Immediate interventions, including control regulatory measures, are essential mitigate these exposures. Enhanced understanding underscores need urgent policy actions protect this vulnerable population.

Particulate matter (PMs) of different origins can cause diverse health effects. Here, a homemade box was used to facilitate real-time measurements breath-borne volatile organic compounds (VOCs) by gas chromatography-ion mobility spectrometry. We have tracked exhaled VOC changes in 228 Wistar rats that were injected with water-soluble PM suspension filtrates (after 0.45 μm) from 31 China cities for 1 h up 1-6 days during the experiments. Rats exposed exhibited significant VOCs within hours, featuring dynamic fluctuations levels acetone, butan-2-one, heptan-2-one-M, acetic acid-M, and ethanol. Subsequently, on fifth sixth day after injection, there notable increase proportion aldehydes (including hexanal-M, hexanal-D, pentanal, heptanal-M, (E)-2-hexenal). The 10 fingerprint patterns mentioned earlier showcased capability indirectly differentiate urban toxicity categorize into four distinct groups based their This study provides valuable insights mechanisms underscores critical role as biomarkers differentiating PMs detecting early signs potential diseases. results this work also provide scientific basis city-specific air pollution control policy development.
