Summary: The main objective of this study is to model the concentration of ozone in the winter season on air quality and detect its impact on population health using machine learning algorithms. Four monitoring stations in Metropolitan Lima during 2017, 2018, and 2019 were included. Exploratory, correlational, and predictive approaches were employed. The results showed that ATE had the highest prevalence of ozone pollution, and pollution peaks occurred at 00:00 and 14:00 in hourly analysis. Linear regression and support vector machine exhibited the best predictive capacity for adjusting ozone concentration.

Summary: The nationwide lockdown implemented in Peru significantly improved air quality in the metropolitan area of Lima, with notable reductions in particulate matter and nitrogen dioxide. However, there was a significant increase in ozone concentration due to the decrease in nitrogen dioxide, indicating a hydrocarbon-limited system in the study area.

Summary: In recent years, the air quality in the HC region has improved, with the number of good air quality days increasing. Ozone, as a typical secondary pollutant, shows stronger inter-city correlations in HC cities. Compared to 2015, fine particulate matter (PM2.5) concentrations decreased significantly in almost all HC cities in 2020.

Summary: In this study, GIS system was used with spatial and meteorological parameters as inputs to identify the distribution and concentrations of PM2.5 pollutants in the Khulna Metropolitan area. A spatial Inter distance weighting method was applied to validate the model. The results showed that the Shonadanga area had higher PM2.5 levels due to low NDVI, elevated LST, and slope variations. Living near roadways was also found to significantly increase vulnerability to PM2.5. The model predictions had higher deviations in the Shonadanga and Fulbarigate zones, indicating the unsuitability of point sampled data for defining overall PM2.5 pollution levels.

Summary: This study investigated the impact of PM2.5 on particle bioreactivity in Taichung City, Taiwan, and found that secondary aerosols were the primary contributor to PM2.5, showing a positive correlation with ROS production in human alveolar epithelial cells. This suggests that secondary aerosols could be an important determinant of air quality deterioration and human respiratory health in urban areas.

Summary: The study assessed the short-term effects of air pollution on hospital admissions in eight municipalities of the Metropolitan Area of Monterrey, Mexico. Most pollutants and municipalities showed associations between an increase of 10% in their concentrations and morbidity, with different age groups being affected differently in various seasons. These results can help decision makers develop public policies focused on protecting vulnerable populations in metropolitan areas in Mexico.

Summary: Most studies indicate that individuals with lower socio-economic status are more exposed to higher air pollution levels. However, research in Europe has shown inconsistent results, often exhibiting non-linear patterns, highlighting the need to better understand the specific context of the relationship between socio-economic status and air pollution. Our study in the Helsinki Metropolitan Area, Finland, using a generalized additive model, reveals an inverted U-shaped relationship between median income and air pollution. Moreover, when considering the spatial distribution of different income groups, low-income individuals are found to be disproportionately affected by environmental disparities compared to others.

Summary: The study highlights the impact of lockdown measures during the COVID-19 pandemic on ambient and household air pollution in China. While outdoor PM2.5 concentration decreased significantly, indoor PM2.5 exposure increased, leading to additional premature deaths. The findings suggest that the reduction in ambient PM2.5 was offset by increased exposure to household air pollution, with rural areas experiencing more significant consequences.

Summary: This study in Rochester, NY found that there is a link between residential proximity to transportation-related sources and individual exposure to polycyclic aromatic hydrocarbons (PAHs) among pregnant women. Decreased socioeconomic status was associated with closer proximity to these sources, which may have adverse effects on fetal health. Therefore, it is necessary to take measures to address this inequality.

Summary: Extreme Weather Events (EWEs) have a substantial impact on the mental health of exposed populations, with high prevalence rates of depression, anxiety, and PTSD. Factors such as higher levels of event exposure, experienced stressors, socio-demographic traits including female gender, lower socio-economic status, and lower education level, contribute to the negative psychological outcomes following EWE exposure. The study findings provide evidence for the development and implementation of public health intervention strategies to mitigate the psychological impacts of extreme weather events.

Summary: This study addresses the issue of harmonic elimination in three-phase power systems caused by non-linear loads. By proposing a modified neural network algorithm with a variable step size in the cost function, faster convergence and overcoming drifting parameters are achieved. The experimental results demonstrate a significant reduction in total harmonic distortion and an improved response time of the power system.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
