Summary: Compound specific isotope analysis has been extensively used to study the environmental processes associated with the transformation of persistent halogenated organic pollutants. Recent advancements have expanded its application to larger molecules and multi-element analysis. However, the instrumental detection limit remains challenging, especially for δ13C analysis, and liquid chromatography-combustion isotope ratio mass spectrometry methods face difficulties in complex mixture analysis. Alternative approaches, such as enantioselective stable isotope analysis, have been explored for chiral contaminants, but more research is needed. In order to analyze new emerging halogenated organic contaminants, there is a need to develop new GC and LC methods for non-target screening using high resolution mass spectrometry prior to compound specific isotope analysis (CSIA) methods.

Summary: Compound-Specific Isotope Analysis (CSIA) is a useful tool for studying the biodegradation of metalaxyl in soil and plants. Microbial degradation was found to have the most significant impact on the degradation of metalaxyl in soil. CSIA was used to investigate the biodegradation and isotope fractionation of metalaxyl in water spinach, showing that both absorption and degradation processes can cause shifts in delta C-13 values. Additionally, the relationship between carbon isotope ratios and residual concentration of metalaxyl was described by the Rayleigh equation, allowing for the calculation of the biodegradation rate of metalaxyl using CSIA.

Summary: The stable isotope fractionation of toluene was studied under dynamic phase exchange. The results showed strong fractionation in both the liquid and gas phases. Numerical simulation suggested that either a strong phase exchange fractionation or direct consumption of gas phase compounds by aqueous phase microorganisms could explain the observed effect.

Summary: Current density has a significant impact on the degradation of pollutants through electrochemical oxidation, and different current densities contribute to cost-effective treatment of organic pollutants. This research combined compound specific isotope analysis (CSIA) and boron doped diamond (BDD) to study atrazine (ATZ) degradation under different current densities, revealing the reaction contributions. The results showed that increasing current density had a positive effect on ATZ removal, with higher center dot OH contributions at higher current densities. The combination of CSIA and DFT calculations provided valuable insights into the pollutant degradation mechanism and demonstrated the possibility of conducting targeted bond cleavage by altering reaction conditions like current density.

Summary: This study used compound-specific isotope analysis to investigate the variation of delta N-15 associated with microbial processes in marine sediment samples. The results showed that the decrease in amino acid concentrations in sediment was accompanied by an increase in delta N-15 values. Phenylalanine displayed a depth-dependent variation in microbial utilization, while glycine showed the highest relative molar contribution and delta N-15 increase in deep sediment. These findings provide an important basis for interpreting the delta N-15 values of amino acids in sediment.

Summary: The isotopic fingerprints of HCH isomers have potential for identifying sources. This study conducted photochemical synthesis experiments to investigate isotopic fractionation associated with the synthesis processes. Different patterns of isotopic fractionation factors were observed, and the variability of isotopic values was related to secondary hydrogen isotope effects and the conformational complexity of HCH caused by the arrangement of C-Cl bonds. The understanding of isotopic fractionation during HCH synthesis can be indicative for source identification in the field.

Summary: The study found that mussels have higher trophic positions, requiring normalization of basal nitrogen isotope ratio. Spatial variations in nitrogen isotopic baselines in mussels reflect different nitrogen sources. Delta N-15 (base-bulk) and Delta N-15 (base-phe) are powerful tools for tracing nitrogen isotopic baselines.

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: This study aimed to develop bacterial consortia for oil recovery and address the issue of oil contamination worldwide. Metagenomics analysis revealed the presence of hydrocarbon degraders in LF2 soil. Three bacterial strains were isolated, and one strain showed the most potential for further bioremediation investigation. The immobilization of consortia improved the bioremediation potential, while the addition of surfactants failed to enhance crude oil degradation.

Summary: Glaciers are ecosystems that contain active biological communities. They act as condensers where pollutants are deposited due to high precipitation rates and cold temperatures. This review aims to provide an overview of the studies on the effects of pollutants on glacier ecosystems, particularly the supraglacial ecosystem. Despite discussions on the distribution of pollutants in glacier environments, no review paper has summarized the current knowledge on the effects of these substances on the ecological communities living in glaciers.

Summary: Anthropic diesel-derived contamination of Mediterranean coastal waters is a major concern. This study investigated the tolerance of the Mediterranean seaweed Caulerpa prolifera to diesel fuel and its potential for degrading hydrocarbons. The results showed that C. prolifera survived and grew in lower concentrations of diesel, but experienced mortality and damage in higher concentrations. The bacterial community associated with C. prolifera, particularly Vibrio bacteria, was found to be positively correlated with the seaweed's health status and its ability to degrade diesel. Overall, this study suggests that protecting and utilizing the symbiotic relationship between C. prolifera and bacteria can help mitigate hydrocarbon contamination in moderately polluted Mediterranean coastal environments.

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.

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.
