Summary: This study investigated the use of gypsum as an adsorbent for the removal of graphene oxide (GO) under different conditions. The results showed that the optimal conditions for GO removal were a solution pH of 8.0, gypsum dosage of 60 mg, initial GO concentration of 80 mg/L, and temperature of 303 K. The adsorption of GO by gypsum followed the Langmuir isotherm model, and it was found to be a spontaneous exothermic process. Characterization of the gypsum-graphene oxide composites provided insights into the mineral interactions and their impact on contaminant removal.

Summary: This study focused on the removal of methylene blue from aqueous solution using Car-St-g-PVP as a cost-effective and biodegradable adsorbent. The experimental results showed that the adsorption process followed pseudo 2nd order kinetics and Langmuir's adsorption isotherms, indicating a chemisorption mechanism. Thermodynamic studies revealed a spontaneous nature of the adsorption process, with increasing randomness and endothermic nature as indicated by positive entropy and enthalpy values. The separation factor (RL) was less than one, confirming the feasibility of the adsorption process. Overall, Car-St-g-PVP demonstrated high efficiency in removing methylene blue and could be a promising option for wastewater treatment.

Summary: A simple synthesis method was used to prepare mesoporous alumina nanorods, which exhibited a high adsorption capacity for the anti-cancer medication DOX. The adsorption behavior of DOX on the alumina nanorods was evaluated under different conditions, and the Langmuir adsorption model was found to fit the data well. The adsorption kinetics followed a pseudo-second-order model, and the adsorption process was endothermic and spontaneous. The alumina nanorods also showed good adsorption performance for DOX in real water samples and could be used for wastewater treatment.

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.
