Summary: This study provides a comprehensive profile of the burden of diabetes attributable to PM2.5 pollution globally and regionally. It finds that globally, a large number of deaths and disability-adjusted life years (DALYs) were attributed to diabetes caused by PM2.5 pollution, with the burden increasing over time. The burden of diabetes attributable to ambient PM2.5 showed a significant increase compared to 1990, while the burden from household air pollution (HAP) decreased. There was a negative correlation between socio-demographic index (SDI) and age-standardized DALY rates (ASDR), with low SDI countries experiencing the greatest burden of diabetes due to PM2.5 pollution.

Summary: The study explores the impact of PM2.5 exposure, household air pollution (HAP), and ambient air pollution (AAP) on cardiovascular disease (CVD) mortality and disability-adjusted life years (DALYs) in South American countries from 1990 to 2019. The findings reveal a significant impact of air pollution on CVD in South America, with regional heterogeneity in the absolute change of PM2.5 concentration levels. AAP was found to be the greatest contributor to the CVD burden in the region.

Summary: Globally, PM2.5 pollution contributed to 292.5 thousand deaths and 13 million disability-adjusted life-years (DALYs) in 2019. Ambient particulate matter pollution (APMP) caused an increase in the burden of type 2 diabetes mellitus from 1990, while household air pollution (HAP) significantly decreased during the same period. Both APMP and HAP were major contributors to deaths and DALYs of type 2 diabetes mellitus among older individuals.

Summary: Exposure to fine particulate matter increases the risk of ischemic heart disease. Based on the Global Burden of Disease Study 2019, the burden of ischemic heart disease caused by ambient particulate matter pollution and household air pollution from solid fuels is significant globally, with different trends observed in regions of varying socio-economic levels.

Summary: The Eastern Mediterranean Region (EMR) experiences high levels of PM2.5 and a significant burden of CVD due to air pollution. Despite reductions in household air pollution (HAP) over the past three decades, there is still ongoing exposure and a rising trend in CVD mortality and DALYs attributable to ambient sources. The analysis suggests substantial opportunities for mitigating the burden of PM2.5-attributable CVD in the EMR region.

Summary: The study estimated the contributions of exhaust and non-exhaust traffic-related PM2.5 and PM10 emissions to total ambient pollution in Banska Bystrica, Slovakia using the AERMOD dispersion model. It was found that on-road mobile sources, particularly non-exhaust emissions, significantly contribute to PM pollution in the study area, highlighting the need for attention to these sources in air quality management efforts.

Summary: Ambient fine particulate matter (PM2.5) pollution is a major problem in China. Reductions in particulate sulfate, driven by desulfurization efforts, have led to a decrease in PM2.5 levels. However, the toxicity of particulate sulfate and its long-term trend is difficult to estimate. Using spaceborne sensors and machine learning techniques, a sulfate prediction model was developed. The model performed well and demonstrated a significant decrease in sulfate levels and associated health benefits.

Summary: Average ambient fine particulate matter (PM2.5) concentrations have decreased in the US, but the health benefits among different racial/ethnic groups are unknown. A study found that for every 1 μg/m³ increase in PM2.5 concentration, there was a significant increase in cardiovascular disease (CVD) deaths among Black individuals compared to non-Hispanic white individuals. The study also showed a reduction in PM2.5-attributable CVD mortality burden between different racial/ethnic groups, although disparities still remained.

Summary: Analysis of the relationship between presence of common DNA sequence inversions and DNA methylation patterns suggests a role for environmental exposures in mediating inversion state-specific methylation patterns. Polymorphic genomic inversions play important roles in evolution, environmental adaptation, and complex traits. Methylation patterns were found to be specific to the inversion state in both datasets, and numerous inversion-exposure interactions on methylation levels were identified.

Summary: This study investigated the association between placental DNA methylation patterns and maternal blood pressure during pregnancy. The results showed that maternal steady blood pressure was directly associated with placental DNA methylation levels, partly explained by changes in cell-type composition. These findings may indicate molecular mechanisms linking maternal hypertension to lung development and early origins of childhood respiratory problems, highlighting the importance of controlling maternal blood pressure during pregnancy.

Summary: This study investigated the neurodevelopmental effects of phthalate exposure during pregnancy and infancy. Using objective measures such as questionnaires and eye tracking tasks, the researchers found that prenatal exposure to monobenzyl phthalate was associated with shorter fixation durations, while postnatal exposure to di(2-ethylhexyl) phthalate was associated with increased time spent looking at a novel face and eyes. Increased postnatal exposure to monoethyl, mono-iso-butyl, and mono-n-butyl phthalates was also linked to faster reaction times and decreased time spent looking at the eyes in a face recognition task. These findings highlight the importance of phthalate exposure in early life on neurodevelopment.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

This study investigated the effects of oral gestational exposure to particulate matter (PM) on ultrasonic vocalizations (USV). The findings suggest that this exposure may lead to social deficits and abnormal gene expression related to neurotransmitter systems. Further research is needed to better understand the effects of air pollution on neurodevelopmental disorders and the neurotransmission systems involved.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.

In this study, a series of catalysts with different elemental doping were prepared using a simple and environmentally friendly method. The S-doped NiCo2O4 catalyst showed excellent catalytic performance for the removal of Tetracycline, with significantly increased kinetic constant and high oxidation and mineralization efficiency in a wide pH range. The degradation process was dominated by non-radical oxidation pathway after S doping, and the overall process moved towards low toxicity.
