Summary: Little is known about the coupling between mercury (Hg) methylation and soil organic matter decomposition in degraded permafrost in high northern latitudes where climate warming is occurring rapidly. In this study, we conducted an anoxic warming incubation experiment for 87 days to explore the interactions between soil organic matter (SOM) mineralization, dissolved organic matter (DOM), and methylmercury (MeHg) production. The results revealed significant promotion effects of warming on MeHg production, as well as increased greenhouse gas emissions and enhanced DOM fluorescence intensities. These findings highlight the complex relationships between warming, greenhouse gas emissions, and MeHg production in permafrost marshes.

Summary: Exogenous dissolved organic matter (DOM) affects the sorption of 4-chloro-2-methylphenoxyacetic acid (MCPA) in soil by altering soil surface properties and MCPA complexed form. Different fractions of DOM, such as hydrophobic neutral and acid insoluble matter, have varying degrees of inhibition on MCPA sorption, while hydrophilic matter has the weakest inhibition.

Summary: Surface ocean bulk and semi-labile dissolved organic matter (DOM) stoichiometry vary across ocean regions with global means of 387:26:1 and 179:20:1, respectively. Surface ocean DOC:DOP and DON:DOP concentration ratios are more variable than DOC:DON concentration ratios. Surface ocean gradients in P-depleted DOM stoichiometries in the Pacific and Atlantic basins reflect variable nutrient stress.

Summary: This study investigated the role of soil mixture blocks (SMBs) in the removal of trace organic contaminants in a multi-soil-layering (MSL) system. The use of zeolite/slag in MSL enhanced the removal of humic substances and building blocks. Results showed that pentoxifylline, caffeine, 17 alpha ethinylestradiol, estrone, and 17 beta-estradiol had high removal efficiencies in the MSL system and zeolite/slag, but lower efficiencies in the sand filter.

Summary: The mineralization of soil organic matter is closely related to climate change, with labile organic matter, microbial community, and soil aggregate size playing important roles in this process. Different soil aggregates treated with long-term non-fertilizers, chemical fertilizers, and animal manure were studied for their impact on dissolved organic matter, beta-glucosidase activity, and microbial community composition. The study found that soil aggregate size, DOM concentration, and microbial community composition all affect the mineralization of organic matter.

Summary: The addition of different oxides in paddy soil affected the mineralization of soil organic matter differently, with ferrihydrite significantly decreasing dissolved organic matter content but increasing microbial biomass carbon content. Oxides like birnessite and ferrihydrite altered soil pH, available nitrogen content, and redox potential, while also impacting soil bacterial abundance and composition. The potential mechanisms of oxides in reducing soil organic matter mineralization included stimulating microbial assimilation of organic carbon, modulating soil properties, and altering bacterial community composition.

Summary: In this study, the dynamics and biodegradation mechanisms of dissolved organic matter (DOM) in eroding agricultural landscapes were investigated. The results revealed that the content of dissolved organic carbon (DOC) was higher in the mid-slope compared to the down-slope, especially at depths of 40-100 cm. The chemical characteristics of DOM differed along the slope, with the up-slope soil containing more microbial-derived substances and the depositional positions rich in humic-like materials.

Summary: The effects of polyethylene (PE) and biodegradable polylactic acid (PLA) microplastics on soil organic matter (SOM) stability and bacterial community were examined in two contrasting soils under varying temperature conditions. Results showed that microplastics addition significantly increased CO2 emissions and dissolved organic carbon (DOC) contents, with PLA being more susceptible to elevated temperature compared to PE. The presence of microplastics also altered the spectral characteristics of DOC and affected the soil bacterial community. The findings suggest the non-ignorable effect of microplastics on soil organic matter stability and the need to consider the interaction between microplastics and soil environment.

Summary: Systemic insecticides and rising temperatures have combined effects on the abundance of Odonata nymphs in paddy fields. The standalone effect of insecticide exposure decreased the Odonata community, while nymphs decreased synergistically with temperature rise in paddy water. However, the impacts of each stressor alone varied among species.

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.
