Summary: Marine sponges play important roles in benthic ecosystems by maintaining water quality and providing shelter and food to other species. A study was conducted to test the vulnerability of benthic ecosystems to oil spills using Cinachyrella alloclada as an experimental indicator. The findings showed that exposure to crude oil and oil dispersant resulted in significant shifts in gene expression in sponges and host bacterial communities, with up-regulation of stress-related pathways, cancer-related pathways, and cell integrity pathways.

Summary: Dispersants can make the separation of oil-water emulsions challenging by reducing oil-water interfacial tension. However, at specific concentrations, dispersants can disperse a portion of the crude oil into small droplets. Complete rejection of oil in separation tests was accompanied by a flux decline due to a decrease in membrane oleophobicity.

Summary: Crude oil spills have negative effects on both wildlife and human health in aquatic environments. Bioassays using model organisms are a convenient method for assessing the potential risks of oil spills. This study evaluated the survival rate, histological changes, morphological changes, and proteomic changes in zebrafish embryos exposed to water accumulated fraction of light crude oil and a surfactant commonly used in oil spill mitigation. The results showed that exposure to the surfactant mixture caused more changes compared to exposure to the crude oil alone. Proteomic changes were particularly significant in zebrafish embryos exposed to the crude oil. The study also compared the hydrocarbon concentrations in the two exposures and found differences in the molecular weight distribution. These findings provide important insights for identifying biomarkers of crude oil exposure in fish species.

Summary: While much is known about the genes and pathways responsible for petroleum biodegradation in marine environments, less is understood about the biodegradation of the chemical dispersant Corexit 9500. This study investigated the genes and pathways involved in the biodegradation of oil and Corexit 9500 in Arctic seawater through metatranscriptomic sequencing. The results revealed a suite of fatty acid degradation genes that were enriched by both oil and Corexit exposure, suggesting a potential pathway for Corexit surfactant biodegradation. The study also identified specific microbial taxa associated with the degradation of oil and Corexit. Overall, this research provides new insights into the biodegradation of Corexit 9500 in the Arctic marine environment.

Summary: Microwave irradiation is an effective and energy-efficient technology for remediating petroleum hydrocarbon-polluted soil. The experiment investigated the performance of microwave heating remediation for light and heavy crude oil-contaminated soil. The results showed that a high removal efficiency of total petroleum hydrocarbons (TPHs) was achieved in a short time, with light crude oil being more efficiently removed. The microwave treatment effectively promoted the removal of different molecular fractions at temperatures below their boiling points, and maintained the soil organic matter at a moderate level for potential reuse.

Summary: This study examined the potential impacts of the offshore oil industry on cold-water marine species in Atlantic Canada, specifically focusing on the sublethal developmental impacts of oil exposure and spill response measures on Atlantic cod. The results showed that increasing oil concentrations led to an increased incidence of sublethal symptoms in cod, such as impaired swimming ability and spinal curvature. The study also found intraspecific variation in the response among cod families, suggesting that sensitivity to oil exposure depends on genetic background.

Summary: The study aimed to prepare and evaluate the demulsification efficiency of two gemini pyridinium surfactant ILs, with TEGP IL showing higher ability to reduce surface tension and interfacial tension. Both surfactants were successfully applied as demulsifiers for W/O emulsions, achieving 100% demulsification at low concentrations for some compositions, with higher activity observed for TEGP IL than MEGPy surfactant.

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.

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: 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.
