Summary: This study presents an innovative methodology for assessing the distribution of Potentially Toxic Elements (PTEs) in soil-polluted areas, utilizing multi-variate statistical and geostatistical algorithms, soil pollution indices, and geochemical & geomorphological/climate variables. Through comprehensive soil sampling in an area around a former As-Hg mine, factors such as Hg, As, Pb, and Sb were identified as main pollutants of concern, with their mobility influenced by climatic/geomorphological variables. The study also found that pollution from chimneys affects the entire study area, while the distribution of PTEs from spoil heaps is more associated with factors like slope and watercourses.

Summary: Monitoring groundwater is crucial in Tarn-Taran district, western Punjab, India due to the overexploitation and contamination of this freshwater source. A comprehensive study revealed that groundwater in the region is suitable for irrigation but not for drinking purposes. High levels of arsenic and uranium were detected, posing significant health risks to the local population. The study also identified both natural and anthropogenic sources of contamination.

Summary: This study assessed the water quality of the Karasu River, a main tributary of the Euphrates River in Turkey, using various methods. The results showed that most stations had excellent water quality, divided into three regions spatially. Nutrient Pollution Index indicated the river was not polluted, while Water Quality Index and Organic Pollution Index suggested the water quality was between good and excellent. Factor analysis identified four potential pollution sources, including anthropogenic, natural, seasonal, and phytoplankton.

Summary: The study focused on the soil potentially toxic elements (PTE) contents in the Armavir region of Armenia. Two clusters were identified, one with PTE of natural origin on volcanic rocks and one with PTE introduced by human activities on alluvial, deluvial, and proluvial sediments. The results indicated higher health risks for specific elements in each cluster.

Summary: This study compared the concentration, distribution, source identification, and risk assessment of PAHs in soils from surrounding areas of an abandoned industrial district and an ecological village in Zhejiang Province, China. The results showed that industrial areas had higher levels of PAHs originating from fossil fuel burning and vehicle emissions, while rural areas had lower levels mainly from biomass burning and vehicle emission. Adults might face higher potential health risk than children, and the overall ecological risk of soil PAH pollution was low in rural areas.

Summary: This paper quantitatively analyzed the characteristics of persistent toxic substances (PTSs) in soil of Ny-angstrom lesund in the Arctic and analyzed the sources and toxicity risks of polycyclic aromatic hydrocarbons (PAHs) in the soil. The study found no obvious spatial distribution of PAHs in the area and identified LMW-PAHs as the main PAHs, mainly tricyclic PAHs. The results showed that the PAHs in soil mainly came from petroleum source and petroleum combustion source, as well as incomplete combustion of coal and wood, with some contribution from atmospheric transport. Ecological risk assessment results showed that the PAHs in soil did not pose a toxicity risk, and the possibility of ecological risk was very low in Ny-angstrom lesund in the Arctic.

Summary: This study investigated the concentrations and sources of 16 priority PAHs in soil at a coking plant in Tangshan. It was found that PAH concentrations were generally higher in surface soil and mainly sourced from coal combustion, the coke oven, and traffic. The areas with higher PAH concentrations were the ammonium sulfate, boiler room, coal blending, and coke oven areas, posing potential toxic and carcinogenic risks.

Summary: This study assesses the water quality of the Geumho River in South Korea using multivariate statistics and the Korean Water Quality Index (KWQI). The results identify factors related to organic pollutants and metabolism, and phosphorus and fecal coliform content. The study also finds that water quality is higher in the spring and summer seasons and in the midstream and downstream regions. To improve water management, interventions should focus on the urban midstream section and spring season.

Summary: Through studying typical copper-producing provinces in China, it was found that 90% of sampling sites were heavily polluted with multiple heavy metals, while soil heterogeneity and mutual interference of multimetals are obstacles in exploring bacterial resistance pathways in contaminated field soils. By analyzing contamination indices and bioindicators, along with multivariate statistical models, it was discovered that different types of heavy metals affect antioxidant enzyme activity, urease-induced precipitation of heavy metals, and excretion of extracellular polymeric substances (EPS) in the soil.

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: 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.
