Summary: Hydrothermal carbonization (HTC) is a promising strategy for converting wet biomass wastes into carbon-condensed solid hydrochars. Co-hydrothermal carbonization of cow manure with grape marc and corn stover did not enhance solid yield or higher heating value synergistically, but it did increase the electrical conductivity of hydrochars. Hydrochars have higher fixed carbon content and lower H/C and O/C atomic ratios than their parent feedstocks, reducing their susceptibility to thermal degradation and decreasing the bioavailability of heavy metals. The land application of hydrochars could potentially reduce phosphorous run-off and eutrophication compared to raw manure.

Summary: Dye wastewater is a major source of environmental pollution due to its high toxicity and difficulty in degradation. Hydrochar prepared through hydrothermal carbonization (HTC) of biomass is an effective adsorbent for water pollutants. Nitrogen-doping (N-doping) can improve the surface characteristics of hydrochar and enhance its adsorption performance. This study investigated the use of nitrogen-rich wastewater as a nitrogen source for N-doped hydrochar production. The N-doped hydrochar exhibited significant adsorption capacity for methylene blue (MB) and congo red (CR) through multiple interaction mechanisms. The adsorption efficiency of N-doped hydrochar can be adjusted by controlling the nitrogen source and pH of the wastewater.

Summary: This study investigated the hydrothermal carbonization of various agricultural and forestry waste with biogas slurry to recover nutrients. The results showed that green bamboo was the most suitable biomass material for nitrogen recovery, while peanut straw was the best for phosphorus recovery. However, potassium could not be recovered through hydrothermal carbonization. The study also found that the total cellulosic content of the biomass influenced nitrogen recovery, and increased metal salt concentration promoted phosphorus recovery. The hydrochars obtained from different biomass samples had varying pore sizes, which had implications for nutrient slow-release and plant growth.

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.
