Summary: Soil toxic metals exhibit strong spatial heterogeneity and have different sources in different regions. This study used the Catreg and geographically weighted regression (GWR) models to extract the main source proxies for different toxic metals and analyze their spatial distributions. Industrial activities were identified as the predominant source of Cd, Hg, and Pb, particularly in high-content cluster areas. Agricultural activities, specifically the overuse of phosphoric fertilizers, were identified as an anthropogenic source for these toxic metals. Soil parent material and slope also played important roles in the accumulation of certain toxic metals.

Summary: The present study investigated the heavy metal pollution in soils from an area with intensive industrial activities in South China. The results showed that the concentrations of Cd, As, Hg, Cu, Ni, Pb, and Zn were higher than background levels in both surface and subsurface soils. The primary sources of heavy metals were identified as agriculture, industry, transportation, and nature. Anthropogenic activities significantly influenced the spatial distribution of heavy metals in soils. The health risks of heavy metal exposure via different routes were found to be at an unacceptable level, with higher risks for adults compared to children. Therefore, monitoring heavy metal pollution in soils in rapidly developing areas, such as South China, is of great importance.

Summary: Arsenic and antimony exhibited different partitioning behaviors in the sediment-porewater profile system in the tributaries of the Three Gorges Reservoir (TGR). Arsenic showed a lower sediment affinity and higher mobility compared to antimony. The different behaviors could be attributed to the chemical fractions of the trace metals and the pH value of the sediments. The understanding of the transport and fate of arsenic and antimony in the aquatic environment was enhanced through this study.

Summary: This study investigated the behaviors of trace metals in sediment profiles within the tributaries of the Three Gorges Reservoir. Arsenic (As) showed the highest migration ability under equilibrium conditions and the highest desorption rate under dynamic conditions. All trace metals were classified as partially sustained, with the diffusion and desorption kinetics limiting the supply abilities of As and other trace metals, respectively. DGT-labile trace metals showed a diffusion trend from sediment to water column, indicating potential risks to water quality. The equilibrium partitioning behaviors revealed the potential labile pool of trace metals in the solid phase.

Summary: This study focuses on characterizing the release of microplastics and non-microplastics from different types of masks after sunlight aging. Non-microplastics were found to be the dominant particles released from masks, with children's masks releasing the highest amount of microplastics. The study also observed a significant increase in microplastic particles released from cut masks compared to whole masks. The non-microplastics found were mainly fibrous and fragmented. It was estimated that these masks could release at least 31.5 trillion microplastics annually in China. This study highlights the urgent need for further research on the environmental impact of mask-related microplastic pollution.
