Abstract There has been a scarcity of comprehensive studies that aim to predict both the levels PM 2.5 particles and their corresponding impacts on human health. To fill this gap, we developed an artificial neural network model AirQ+ software concentrations assess associated health effects. The ANN utilized five distinct input parameters, specifically wind velocity, orientation, atmospheric temperature, relative moisture content, levels, observed within time frame 2018 2019. concealed stratum comprised total ten neurons, in addition presence output layer. MLP demonstrated strong correlations at each stage: 0.908 (training), 0.910 (validation), 0.914 (testing), 0.907 overall. RMSE was determined as 6.52 µg/m 3 when evaluating network, thus indicating notable predictive precision exhibited by multilayer perceptron (MLP) forecasting concentration particles. software, created World Health Organization (WHO), employed magnitude consequences concentrations. average throughout duration study recorded 26.5 μg/m , which exceeds recommended limit provided WHO factor 5.3. estimated proportions numbers deaths attributed various conditions. Specifically, chronic obstructive pulmonary disease (COPD), ischemic heart (IHD), lung cancer (LC), stroke, all-cause mortality accounted for approximately 11.67%, 15.02%, 13.25%, 15.225%, 9.45% respectively. number were 19,195 all causes, 10,063 COPD, 564 IHD, 1,063 cancer. findings investigation demonstrate high degree reliability methodologies utilized. Through utilization these approaches, individuals positions authority responsibility can aptly evaluate cost-benefit analysis, leading reduction casualties mitigating economic burdens society.

The objective of this study was to estimate the health effects attributed PM2.5 exposure in southwest Iran. In order HA-CVD, HA-RD, LC-M, I-As children, RAD, and WDL, exposure-response function method used. annual mean regularly exceeded 5.26-8.5 times from 2021 limit value established by WHO. dominance PM2.5/PM10 ratio decreased -34.6% 2015 2020. results showed that risks HA-CVD (- 51. 9), HA-RD 68.7%), LC-M 43.6%), 52.1%), RAD 56.8%), WDL 58.7%) declined per 105 inhabitants between 2018 2020 . Reducing particulate emissions industries road traffic led lower PM2.5, which will be effective decrease mortality rate.

This study investigates the association between fine particulate matter (PM2.5) exposure and acute exacerbations of chronic obstructive pulmonary disease (AECOPD). A retrospective analysis was conducted on 1284 AECOPD hospitalizations at Shanxi Medical University's Second Hospital from 2018 to 2022. data paired with Shanxi's average monthly PM2.5 Tracking Air Pollution in China (TAP) dataset. Correlations levels clinicopathological features were assessed using ANOVA Spearman's correlation. Higher concentrations observed during February-April November-January, correlating increased admissions (r = 0.754), outpatient visits 0.799), emergency 0.447), ICU transfers 0.860). Among patients, 76.5 % smokers 68.4 over 60 years old. Inflammatory markers (leukocyte neutrophil counts, eosinophil percentages, C-reactive protein), D-dimer levels, PaCO2, fibrosis indicators showed positive correlations whereas Pulmonary Function measures (FEV1/ FVC, FEV1 %) PaO2 inverse correlations. Elevated significantly increases risk AECOPD, linked heightened inflammation, fibrosis, diminished function, majority these patients are old or smokers. provides valuable theoretical practical insights for proactive prevention management clinical settings.

This paper discusses the impact of rapid economic development on air quality in Emirate Dubai, United Arab Emirates (UAE). Dubai is one fastest-growing cities world, with a population increase approximately 80 × over last 60 years. The concentrations five criteria pollutants (CAPs) including carbon monoxide (CO), nitrogen dioxide (NO2), particulate matter smaller than 10 μm (PM10), ozone (O3) and sulphur (SO2) were studied from 2013 to 2021 at 14 regulatory monitoring stations. Results show that biggest improvements pollution are for primary NO2 SO2, reductions 54% 93% respectively period studied. Gross domestic product (GDP), growth energy consumption significantly negatively correlated SO2 strongly positively PM10. CO number buildings completed, while results O3 inconclusive.

Fine particulate matter (PM2.5)-related health issues have received increasing attention as a worldwide public problem, and PM2.5-related chronic kidney disease (CKD) has been emerging over the years. Limited research focused on mechanism of PM2.5-induced disease. To investigate impact PM2.5 its potential mechanism, we generated PM2.5-exposed C57BL/6 mouse model by using Shanghai Meteorological Environment Animal Exposure System (Shanghai-METAS) for 12 weeks, urine, blood tissues were collected. The pathological changes function measured after exposure weeks. Along with glomerular damage, tubular damage was also severe in mice. results mRNA-seq indicate that pyroptosis is involved. Pyroptosis defined caspase-1-dependent programmed cell death response to insults. expression nucleotide-binding oligomerization domain-like receptor family pyrin domain containing 3 (NLRP3), Caspase-1, gasdermin D (GSDMD) IL-1β detected. NLRP3 inflammasome activation subsequent observed Bumpt cells too. At meantime, inhibitors caspase-1 applied exposed cells. It turned out significant rescue effect inhibitors. This study revealed new insights into injury specific well morphological changes, important role dysfunction.
