Summary: The composition of dissolved organic matter (DOM) in groundwater near landfills varies depending on the age of the landfill, with newer landfills showing higher levels of tryptophan and tyrosine, while older landfills have more protein-like and humic-like substances. Leachate leakage introduces unique dye-derived fluorescent matter into contaminated groundwater, leading to increased concentrations of humic-like substances, DOM molecular weight, and microbial activities, making them reliable indicators of groundwater pollution. Identifying leachate pollution can be achieved through a fluorescence method, with the results providing insights into monitoring, early warning, and addressing groundwater pollution in landfills.

Summary: This study investigated the potential release characteristics of dissolved organic matter (DOM) from hydrochar (HDOM) under various environmental conditions. It was found that alkalinity and high temperature conditions can enhance the leaching amount of HDOM and change its chemical quality. Released HDOM may have significant impacts on ecosystem functionality.

Summary: This study investigates the transformations of dissolved organic matter (DOM) in stabilization ponds co-treating sanitary sewage and landfill leachate. The results show the prevalence of humic-like fluorophores associated with landfill leachate, with anaerobic ponds exhibiting higher fluorescence removal than facultative ponds. The influent and final effluent display complex DOM characteristics, with influent characteristics linked to the addition of landfill leachate and effluent characteristics likely due to the release of soluble microbial products (SMPs).

Summary: In this study, a new fluorescence approach based on excitation emission matrix (EEM), combined with a new algorithm called matrix reconstruction coupled with prior linear decomposition (MR-PLD), was developed to simultaneously quantify multiple dissolved organic matter (DOM) components. The method was validated using simulated water samples and showed higher accuracy and convenience compared to other methods. The anti-interference performance of MR-PLD was also tested using both simulated and experimental methods. Real water samples from natural waters and wastewater treatment plants were analyzed to confirm the method's robustness. This study provides a new approach for characterizing DOM and exploring its environmental impacts.

Summary: Biological degradation plays a significant role in the turnover of aquatic dissolved organic matter (DOM). The specific biological pathways involved in DOM degradation, however, remain unclear. In this study, the changes in DOM during a 28-day incubation in a karst river were analyzed using fluorescent excitation-emission matrix (EEM) combined with parallel factor analysis (PARAFAC) and peak picking. Different components of DOM were identified, and the results indicated that biogenic DOM was preferentially consumed during the incubation. The study also demonstrated the usefulness of fluorescence measurement in deciphering riverine DOM biodegradation.

Summary: Dissolved organic matter (DOM) in saltmarshes plays a crucial role in the production of greenhouse gases (GHG). Specific types of DOM, such as protein-like DOM, are likely to produce CH4, while humic-like DOM tends to produce CO2. Both hydrodynamics and chemical reactions influence GHG emissions, with hydrodynamics being more important in the short term and chemical reactions being crucial on seasonal scales.

Summary: We used fluorescence excitation-emission matrix (EEM) spectroscopy and parallel factor analysis (PARAFAC) to track hotspots of raw wastewater in low- and medium-order urban streams. We proposed that specific ratios of fluorescence components could distinguish when and where untreated wastewater is introduced to urban streams, and this was validated by the detection of contaminants at high concentrations. Based on the data, we identified impacted sites in rural/suburban areas and urban sections affected by sewer issues. The EEM-PARAFAC technique was considered a quick, easy, cost-effective, and scalable method to screen for failing sewer infrastructure in low-order streams.

Summary: This study simulated the generation process of BC-derived DOM by setting different leaching times, revealing that low aromatic BC-derived DOM may contain aromatic phenolic compounds. Longer leaching times contribute to the accumulation of complex, hard-to-use organic matter and lower the germination index of plants.

Summary: Recycling drinking water treatment residue (DWTR) to make ceramsite can provide environmental and economic benefits in water environment remediation. The key parameter for ceramsite production is the sintering temperature. Ceramsites made from different DWTR have varying properties and require specific ingredients preparation. DWTR based ceramsite is identified as non-hazardous material and has the ability to adsorb heavy metals.

Summary: This study investigated the removal of triclosan (TCS) in soil amended with different types of compost. The results showed that compost addition significantly enhanced the removal of TCS, with food waste compost being the most efficient. The increase of soil nutrient factors and the decrease of pH stimulated the abundance of key dominant bacteria and fungi, which were found to have a potential effect on TCS degradation. In addition, four bacterial biomarkers were identified as the key TCS-degraders. The findings suggest that compost amendment can effectively degrade TCS in soil.

Summary: Network control theory is used to model the neurophysiological dynamics of the brain based on the structural connectome constructed from diffusion MRI. This study explores the changes in average and modal controllability in children with drug-resistant epilepsy compared to healthy controls. The results suggest that increased thalamocortical connectivity may be responsible for the observed changes in controllability. The findings also indicate that controllability changes can be used as a manifestation of brain network dysfunction in epilepsy and may help in understanding the pathophysiology of the disease.

Summary: The use of ceramsite as a filtration material in water treatment is popular, and the development of low-cost, high-performance, and environmentally friendly ceramsites has gained attention. This study focuses on exploring the use of drinking water treatment residue (DWTR) to make ceramsite for water treatment. The results show that DWTR-based ceramsites can be fabricated using sintering and non-sintering methods. Further research is needed to evaluate the performance and potential for pollution control of DWTR-based ceramsite-constructed filtration systems, as well as the stability and safety of raw DWTR-based ceramsite.

Summary: Gas emitted from landfills contains a large quantity of volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs), some of which are carcinogenic, teratogenic, and mutagenic. The global hazards of VOCs and SVOCs in landfill gas to human health remain unclear. To quantify the global risk distributions of these pollutants, the composition and concentration data of VOCs and SVOCs from 72 landfills in 20 countries were collected and their human health risks were assessed. Organic compounds in landfill gas primarily result from the biodegradation of natural organic waste or the emissions and volatilization of chemical products. The respiratory system, particularly the lung, was found to be the major target organ of VOCs and SVOCs, with additional adverse health impacts ranging from headache and allergies to lung cancer. Aromatic and halogenated compounds were the primary sources of health risk, while ethyl acetate and acetone from the biodegradation of natural organic waste also exceeded the acceptable levels for human health. Overall, VOCs and SVOCs affected residents within 1,000 m of landfills. Air temperature, relative humidity, air pressure, wind direction, and wind speed were the major factors that influenced the health risks of VOCs and SVOCs. Currently, landfill risk assessments of VOCs and SVOCs are primarily based on respiratory inhalation, with health risks due to other exposure routes remaining poorly elucidated. In addition, potential health risks due to the transport and transformation of landfill gas emitted into the atmosphere should be further studied.

Summary: Recent work has found that the relationship between structural and functional connectivity in the human brain varies across different regions, with reduced connectivity observed in the sensory-association cortical hierarchy. This study suggests that intracortical myelination and excitation-inhibition balance play a role in mediating the heterogeneous expression and temporal variance of structure-function coupling.
