Summary: This study evaluates the composition of dissolved organic matter (DOM) in Lake Mendota as a function of time and depth. The researchers analyze dissolved organic carbon concentrations and optical properties of samples collected from June to November, and use Fourier transform-ion cyclotron resonance mass spectrometry (FT-ICR MS) to investigate DOM composition at the molecular level. The results show that DOM composition varies both temporally and with depth, with photochemical reactions and redox conditions playing important roles. The findings have implications for understanding the flux of CO2 in lakes and the impact of lake eutrophication.

Summary: The seasonal dynamics of CDOM and DOC in Poyang Lake are important for understanding biogeochemical processes and water quality. Rivers and wetlands greatly influence the quantity and quality of CDOM. The alternations of flood and dry periods have different effects on CDOM and DOC. Wetlands contribute a higher abundance of CDOM and DOC to the lake with lower aromaticity.

Summary: The lability and controlling factors of arsenic (As) at the sediment-water interface (SWI) were investigated using various sampling techniques and chemical analyses. The results showed that the migration of As in the lake was influenced by seasonal changes and the presence of organic matter (OM) and iron oxides. These findings provide valuable insights into the behavior and fate of arsenic in similar environments.

Summary: This study investigates the photoreactivity of dissolved organic matter (DOM) from different sources in the Lake Taihu basin. The results show that the original composition and sources of DOM are closely related to its photoreactivity. DOM from macrophytes releases soluble components under light exposure, while DOM with higher aromacity shows photobleaching effects and increased humification degree. Allochthonous anthropogenic DOM exhibits stronger photo-ammonification. The form of inorganic nutrient releases during DOM photolysis also varies with the original DOM sources.

Summary: Lake respiration is supported by a combination of autochthonous and allochthonous resources, with temperature and organic matter inputs influencing the process. However, the variability in daily inputs can lead to fluctuations in respiration rates, with nutrients not directly tracking phytoplankton blooms in the lakes. Changes in hydrologic, climatic, and land use factors may result in linear responses in ecosystem processes like respiration.

Summary: The release of dissolved organic matter (DOM) from Cd contaminated soils is linked to the mobilisation of Cd-DOM complexes, with organic matter-rich soil amendments exacerbating this process. The quantity and quality of DOM determine the proportion of dissolved Cd that forms mobile complexes, affecting Cd transport from contaminated soils. Structural properties of DOM play a key role in the mobilisation of Cd from contaminated soils, as observed in this study.

Summary: The input of mercury (Hg) into ecosystems has increased significantly since the industrial revolution, and methylmercury (MeHg) is the most concerning species in aquatic ecosystems due to its neurotoxicity and ability to bioaccumulate in the food chain. Dissolved organic matter (DOM) plays a crucial role in the transformation of aquatic Hg. This study collected water samples from 373 sites globally and found that Hg availability was the dominant factor influencing MeHg concentration in water, followed by DOM.

Summary: Algal organic matter (AOM) hinders the photodegradation of neurotoxic methylmercury (MeHg) in eutrophic lakes due to dynamic changes in AOM during algal decomposition. The inhibitory effect of AOM on MeHg photodegradation varies among lakes and their eutrophication states. Reactive oxygen species (ROS), including hydroxyl radical, singlet oxygen, and DOM-D-3*, play different roles in driving MeHg photodegradation throughout the algal decomposition process. This study highlights the importance of considering AOM-MeHg interactions in predicting MeHg risks and suggests integrating them into Hg biogeochemical cycling models.

Summary: Mercury contamination in the Florida Everglades has been a persistent concern. This study examined mercury and methylmercury dynamics in different media and found strong linkages between air, water, and biota in the system. Changes in hydrology and climate were the main drivers of temporal patterns across different matrices. Unlike other regions, there was no evidence of a decline in atmospheric mercury deposition in this region. The study also identified geographic regions susceptible to higher methylmercury bioaccumulation, particularly in the Shark River Slough and Coastal areas. Improved water quality and flow rates, two key targets of the restoration program, are expected to reduce methylmercury production and exposure.

Summary: A study found that microbial processes play important roles in the transformation of terrigenous organic matter (TOM) during freshwater-seawater mixing, including the biodegradation of dissolved organic matter, changes in bacterial community structure and diversity. In addition, the sinking of surface-derived TOM may lead to increased transformation of dissolved organic matter and carbon storage in the bottom water.

Summary: Lakes play a crucial role in the global carbon cycle, and understanding the interactions between microbial and dissolved organic matter (DOM) diversity is essential for predicting the function of lake ecosystems. This study used high-throughput sequencing and mass spectrometry to investigate the structure and patterns of DOM and microbial communities in six lakes. The results showed a strong correlation between molecular-level DOM diversity and the diversity of microbial communities, indicating a dynamic feedback mechanism. The study also found that deterministic assembly processes governed DOM composition, while microbial community composition was highly variable across lakes with different environmental conditions. Overall, understanding the coupling between DOM and microbial communities is important for predicting future lake ecology and function.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
