Summary: The fate of nanoplastics in aquatic environments is dependent on their concentration, particle size, salinity, and organic matter conditions. Nanoplastics can either remain dispersed or aggregate with natural colloids. The size of nanoplastics has a significant impact on their fate, and the distribution of nanoplastics varies across different environmental conditions.

Summary: In this study, we investigated the changes in physicochemical properties of polystyrene microplastics generated from a disposable cup due to UV-weathering, and their impact on microplastic transport potential and contaminant sorption ability in simulated freshwaters. UV exposure led to a decrease in microplastic hydrophobicity, increase in density, carbonyl index, and microscale roughness. Settling velocity also increased, indicating enhanced deposition to sediments. Weathered microplastics showed reduced sorption capacity for a hydrophobic contaminant compared to unaged ones. These findings provide new insights into the risks and behavior of microplastics in aquatic environments.

Summary: The interaction between halloysite and hematite affects the environmental fate of organic pollutants by altering their adsorption and degradation processes, as demonstrated in this study. The presence of hematite changes the Zeta potential of halloysite, while halloysite enhances the dispersion of hematite and improves the activation of H2O2 for degradation of pollutants. The hydroxyl radicals were identified as the main reactive species for the degradation process, highlighting the importance of understanding the migration, enrichment, and degradation of organic pollutants in soil.

Summary: In this study, the porous metal-organic framework MIL-88B was synthesized and characterized, and its modified form NH2-MIL-88B was found to have a higher adsorption capacity than MIL-88B. The experiments showed that NH2-MIL-88B had high adsorption capacity for direct red dye 23 at lower pH values and complete removal of dye was achieved under optimal conditions.

Summary: This study models the transport and fate of 19 metals in the Parauapebas river in Brazil, evaluating the risks associated with threshold exceedances. The results indicate iron, manganese, and aluminum as the main substances of concern for surface water quality. Point sources have a larger impact on water quality during the dry season, while diffuse contributions have a larger impact during the rainy season, especially in deforested areas. The modeling framework can guide pollution control and remediation efforts for stakeholders in the public or industrial sectors.

Summary: This study constructed a method for formulating a discharge inventory of soil pollutants based on contaminant tracing and analyzed a phosphate fertilizer-sulfuric acid site as an example. It was found that arsenic contamination was mainly caused by sulfur-iron slag and tailing leaching, with other pathways having minimal impact. The established discharge inventory will contribute to the refined management of site pollution and reduction of source contaminants discharge.

Summary: The study investigated the presence and distribution of LABs in Baihaimian River, finding that environmental factors, river flux, and sediment properties may affect the spatial distribution of LABs. Significant correlations were observed between total nitrogen, ammonia nitrogen, and LABs in river water, indicating a common domestic wastewater source. Additionally, the positive correlation between total organic carbon and LABs in sediments suggests that total organic carbon serves as a controlling factor for the redistribution of LABs.

Summary: This study aimed to investigate the aging characteristics of disposable surgical masks (SMs) and the effect of different aged layers of SMs on phenanthrene (PHE), tylosin (TYL), and sulfamethazine (SMT) under urban environmental stressors. The results showed that UV exposure caused more severe aging of the SM layers than ozone, and the middle layer made of melt-brown fabric displayed the highest degree of aging. The findings highlight the environmental effects of new microplastic sources and coexisting pollutants under the influence of COVID-19, contributing to the accurate evaluation of the biological toxicity of SMs.

Summary: A water environment quality evaluation and pollution source analysis were conducted in the Tuojiang River Basin using grey water footprint, decoupling theoretical model, and correlation analysis. The results showed that the water environment quality improved as the grey water footprint decreased. Total phosphorus was the primary pollution source, and the economic development level and water environment showed high-quality coordination. Farmland and stock breeding pollution contributed the most to agricultural pollution and were the main sources of the grey water footprint. Pearson's correlation analysis revealed that the pollutants came from imported pollution in tributaries and agricultural pollution, especially from stock breeding and farmland irrigation. This study provides a decision-making basis for strengthening the ecological barrier in the Yangtze River.

Summary: Unprecedented urbanization-induced population migration in China has significantly impacted anthropogenic pollutant discharge. The effects of population migration on pollutant discharge peaked in 2002, but started contributing to pollutant reduction from 2010 onwards. Population migration is highly beneficial for reducing chemical oxygen demand (COD), but the pollution reduction resulting from the demographic bonus phenomenon is limited to urban areas. The per capita and total amount of anthropogenic pollutant discharges in rural areas have exceeded those in urban areas, suggesting a need for more attention to rural areas in pollution control strategies.

Summary: This study combines deep learning neural networks (DLNNs) with SHapley Additive exPlanation (SHAP) to predict the risk of mental disorders (MDs) on a population level and provide explanations for the risk factors. The results suggest that NO2, SO2, and CO make significant contributions to feature attributions in mixed air pollutant scenarios, with NO2 at high concentrations being associated with an increased risk of MDs. Additionally, interactions between different gaseous pollutants show various effects, with some displaying antagonistic effects and others revealing synergistic effects.

Summary: Epidemiological evidence suggests a significant association between short-term exposure to air pollution and mortality risk for circulatory system diseases, particularly in a growing Chinese city. The study conducted in Nanjing showed that increases in PM2.5 and PM10 concentrations were associated with higher daily death counts of CSD, with exposure-response curves showing a non-linear relationship. Stratified analysis indicated potential vulnerability to PM exposure in certain groups like the elderly and during cold seasons.

Summary: This study investigated the effects of NaOCl dose and solution pH on the properties of PVDF ultrafiltration membranes. The results showed that membrane pores increased with exposure time prolonging, and more pores were observed at pH 8 aging condition. Different chemical groups were formed under different pH conditions. The hydrophilicity and pure water permeability of the membranes had slight changes during NaOCl aging process. The antifouling properties of some membranes were slightly improved, while others showed severer flux decline with humic acid filtration.

Summary: The association between malaria incidence and climatic factors is controversial, hindering the progress of the Global Malaria Program. This study evaluated the relationship across all malaria endemic countries in Africa and the Asia-Pacific region. Using two decades of data, the study found heterogeneity in malaria incidence and reductions in the disease burden in Asia-Pacific countries, with exceptions in Africa. The study also identified positive associations between malaria incidence, minimum temperature, and precipitation in African countries, while several Asia-Pacific countries showed negative effects of precipitation.
