Summary: This study assessed the effects of farmland abandonment on soil microbiota and contaminant residues in L. barbarum fields in Ningxia, China. The results showed that both bacterial and fungal diversity increased after abandonment. The abandoned fields had enriched potentially beneficial microbial communities, reduced heavy metal accumulation, and enhanced pesticide degradation.

Summary: Evolutionary responses to human-mediated environmental change, such as pollution, in the wild plant Silene uniflora have been found to be complex and polygenic. Although rapid adaptation to extreme conditions like zinc contamination occurred independently in different mine populations, genetic differentiation was only partially shared between these populations. The study suggests that predicting evolutionary outcomes based on genomic data can be challenging due to idiosyncrasies at the genetic level.

Summary: This study evaluates the risks of arsenic, copper, zinc, and lead contamination in the soil of two important mining areas in Chile and finds that arsenic poses the highest risk. Chile currently lacks specific legislation on legal limits for soil contamination by trace elements, but it is necessary to establish background concentrations and develop national legislation to regulate soil metal contamination.

Summary: This study investigates the atmospheric heavy metal pollution in the Qinghai-Tibet Plateau region of China. The results show that mosses in the area have higher concentrations of zinc and copper, while cadmium concentrations are low. The southern region of the plateau has severe atmospheric copper pollution, possibly due to large-scale mining activities.

Summary: This study reviewed publications from the past 20 years and used meta-analysis to calculate the input fluxes of heavy metal(loid)s in agricultural soil in different regions of China. It was found that atmospheric deposition is the major source of heavy metal(loid) input, while fertilizer and manure contribute relatively less. Cd poses the most significant risk to agricultural soil environment in China, and its safety limit will be reached within 100 years in most regions. The Huang-Huai-Hai region is of particular concern due to comprehensive pollution.

Summary: The study revealed the effects of aquaculture effluents on metal pollution in adjacent mangrove wetlands and the ecological role of GRSP. Long-term effluent discharge increased the potential toxicity of metals, and effluent disturbances changed the surface morphology and functional group contents of GRSP. This study provides insights into using GRSP as a bioindicator for aquaculture pollution.

Summary: The study demonstrated that hydrogels derived from modified GGM hemicellulose are effective in adsorbing Cu(ii), Cd(ii), and Pb(ii) ions, with the H3 hydrogel showing superior adsorption properties compared to others while also exhibiting lesser swelling. This suggests that modified GGM hemicelluloses can serve as renewable adsorbents for removing these heavy metal ions from aqueous solutions.

Summary: In low Pb soils, splash and atmospheric deposition accounted for 84% and 78% of lettuce Pb in NYC and Ithaca, respectively. In high Pb soils, splash and atmospheric deposition accounted for 88 and 93% of Pb on lettuces, with splash being the dominant mechanism. Soil covers were shown to be effective at significantly (p < 0.05) reducing lettuce Pb contamination, and mulching is strongly recommended as a best practice.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

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: The choice of workflow in wastewater surveillance has a significant impact on SARS-CoV-2 concentrations, while having minimal effects on HF183 and no effect on HAdV 40/41 concentrations. Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

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: Growing pressure from climate change and agricultural land use is destabilizing soil microbial community interactions. Little is known about microbial community resistance and adaptation to disturbances, hindering our understanding of recovery latency and implications for ecosystem functioning. This study found that anthropic disturbance and natural disturbance have different effects on the topology and stability of soil microbial networks.

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.
