Summary: The study found that the concentrations of soil HMs in Jinhua City were mainly highest in Zn, Cr, and Pb. None of the determined soil HMs exceeded China's risk screening values for agricultural land contamination. The spatial distribution of soil HMs showed different levels of autocorrelation and environmental risk probability in different areas, with the majority of farmland in Jinhua City falling within safe utilization zones.

Summary: Visible and near-infrared reflectance (VNIR) spectroscopy is a promising alternative to detect heavy metal contamination in suburban soils. This study explored the spatially varying relationships between soil chromophores and heavy metals and investigated the feasibility of using multi-scale geographically weighted regression (MGWR) for heavy metal estimation with VNIR. The MGWR method outperformed its competitors, resulting in an increase in the coefficient of determination and a decrease in the residual sum of squares. The spatial correlation between heavy metals and TFe2O3 was found to be the main reason for the successful estimation of Cr and Ni using VNIR.

Summary: The proper management of e-waste poses significant economic and environmental challenges due to the vast quantity of e-waste, potential for extracting precious metals, and risks of environmental contamination. This study focused on the leaching potential of elements from computer mainboards across different time periods, highlighting shifting metal contamination patterns and the release of specific elements as potential geochemical tracers for improper recycling activities. Further assessments and ecotoxicological studies are needed to fully understand the leaching potential of pollutants from improperly recycled e-waste.

Summary: Shipbreaking activities release hazardous waste that harms both workers' health and the environment. Over the past four decades, shipbreaking sites have shifted from developed regions to Bangladesh, India, and Pakistan, leading to a significant increase in waste emissions in these countries. However, the study predicts a considerable reduction in waste emissions by 2050.

Summary: This study analyzed the spatial distribution and influencing factors of soil nutrients in the semiarid Anding district farming region in northern China. The results showed considerable variability in soil nutrient content, with soil organic matter, total nitrogen, and available phosphorus showing increasing trends from the middle to the northeast and southwest, while available potassium showed the opposite trend. Factors such as soil texture, irrigation method, and water source type significantly influenced the distribution of soil nutrients.

Summary: The study indicates that while TMM concentrations in soil were mostly below permissible limits, Hg and Cd may pose potential ecological risks due to slight accumulation. Among the 24 crop samples, lead accumulation was highest in leaf crops, followed by tuber and seed crops. Key factors associated with TMM accumulation in crops included available potassium, cation exchange capacity, soil organic matter, and available phosphate among selected soil properties.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
