Summary: Industrial chemicals are often found in sediments due to previous spills, with global remediation strategies focusing on natural attenuation through in situ abiotic and biotic processes. Compound-specific isotope analysis serves as a diagnostic tool to identify and quantify degradation processes, distinguishing between abiotic and biotic degradation. Through stable isotope profiles, this study found evidence of biodegradation and subsequent transformation of contaminants, highlighting the importance of multiple lines of evidence for predicting remediation outcomes.

Summary: This study investigated the collective weathering processes and microbial composition changes of diluted bitumen (DB) spilled in fresh water. The contents of total organic carbon (TOC), benzene/toluene/ethylbenzene/xylenes (BTEX), and polycyclic aromatic hydrocarbons (PAHs) in the water decreased with time, but the final contents were higher in warm water than in cold water. The microbial shifts coincided with the changes of PAHs in the waters. In addition, the density and viscosity of the oil increased due to weathering.

Summary: Determining the origins of nitrate is crucial for improving groundwater management in hydrogeological catchments. This study used stable isotopic composition analysis to identify the sources of nitrate in a karst system. The results showed that the upper Jurassic karst confined aquifer and the upper Cretaceous unconfined aquifer have the same nitrate sources. Additionally, the study found that the lower aquifer can be fed by the upper Cretaceous unconfined aquifer, contrary to previous belief. Overall, this work provides important insights for the understanding and management of water quality in karstic hydrogeological catchments.

Summary: This study investigates the effectiveness of dispersant use in the Baltic Sea, focusing on oil degradation rates and bacterial community structures. Results show that coastal seawater from the Gulf of Bothnia and Gulf of Finland have the highest oil degradation gene abundances and removal rates, while seawater from the Norwegian Sea have the lowest. Dispersant usage has apparent effects on bacterial communities, but its impact on biodegradation rate remains unclear due to uncertainties in chemical analysis and oil concentration variations.

Summary: The study investigated the decrease in oil-induced soil hydrophobicity under different environmental conditions and the relationship between hydrophobicity and hydrocarbon content. Results showed that the addition of water, nutrients, and biosurfactants accelerated the reduction in hydrophobicity and decomposition of hydrocarbons. However, soil hydrophobicity remained severe in all treatments at the end of the incubation period, despite significant removal of total petroleum hydrocarbons.

Summary: Stable isotopes of water were used to investigate the role of fog in cloud forests. The isotopic composition of rain and fog water and their variability were analysed for a Macaronesian cloud forest in Tenerife. The results showed little differences in the isotopic signature of fog and rain, indicating their common water sources and moisture conditions. The isotopic composition of rain and fog showed low correlation with temperature and total rainfall, but high anticorrelation with rainfall totals in the Canary Islands, which suggests a relationship between moisture source region and transport patterns.

Summary: Various analytical techniques were used to study the weathering process of four crude oils, revealing that the molecular composition and structure information play a significant role in the process. Low molecular weight compounds were found to be more volatile, and nitrogen compounds were oxidized to a certain extent during weathering. These findings provide valuable insights into the short-term weathering process of petroleum hydrocarbons.

Summary: The study investigated the nitrate contamination and nitrogen cycling in the Babu karst aquifer in Guizhou Province, Southwest China using multiple stable isotopes and models. The results showed that nitrogen fertilizer, manure and sewage, and soil organic nitrogen were the main sources of nitrate in winter, and nitrification was the primary nitrogen transformation process. Denitrification could also occur locally, contributing to nitrate enrichment.

Summary: Mediterranean areas face challenges of water salinity and pollution. This study investigated the sources of water salinity and pollution using chemical and isotopic indicators. The results showed high salinity levels in water samples, making them unfit for human consumption. The mineralization of groundwater in the area is controlled by various processes including carbonate dissolution, evaporite dissolution, ion exchange, and sewage invasion. Scientific results like these are valuable for decision-makers in improving sustainable groundwater management in water-stressed regions.

Summary: Bromoform (CHBr3) is an important precursor of reactive bromine species in the troposphere and stratosphere. Previous models have only considered natural production of CHBr3 from marine organisms, but this study finds significantly higher levels of CHBr3 in water and air due to anthropogenic sources in an industrialized area. These findings suggest that industrial discharges may be an important missing factor in estimates of organic bromine flux to the atmosphere.

Summary: Although multielement isotope fractionation studies have been well-established for point-source pollution, they are only emerging for diffuse pollution by micropollutants like pesticides. This study found that chlorine isotope fractionation can be a robust indicator of chloroacetanilide degradation, with distinct patterns observed for different degradation pathways. The 3D isotope approach allows for differentiation of transformations that may not be distinguishable based on C and N isotope data alone.

Summary: The transfer of pesticides from agricultural soils to food and drinking water is a major health concern. This review focuses on the use of multi-elemental compound-specific isotope analysis to study the sources and transformations of pesticides in agricultural soils. Advanced extraction and purification techniques as well as analytical techniques for measuring stable isotope composition of pesticides are discussed. A unique dataset of isotopic compositions of various pesticides and isotope fractionation values for different compounds is reported, providing insights into the mechanisms of pesticide transformation.

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: 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.

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.
