Summary: The study revealed that both BSA and HA significantly inhibited the bioaccumulation and translocation of PFASs in wheat roots and shoots, with BSA having a greater impact than HA. The higher binding affinities of the four PFASs with BSA than with HA explained this difference. Additionally, the inhibition impacts of the BSA-HA mixture (1:1) were lower than BSA alone.

Summary: This study investigated the migration behavior of PFOA and PFOS in the presence of dissolved organic matter (DOM) and under different solution conditions. The results revealed that the concentration of DOM had a contrasting effect on the migration of PFOA and PFOS. Additionally, the ionic strength and cation type of the solution were found to influence the transport of PFOS and PFOA.

Summary: The conversion of perfluorinated carboxylic acids and perfluorinated sulfonic acids into perfluoroalkenes in aqueous solutions is studied using electronic structure methods. It is shown that aluminum trifluoride can enable these conversions at room temperature within a short time. The mechanism involves the extraction of F- from either the carboxylic or sulfonic acid anions by AlF3, resulting in the formation of a stable AlF4- anion and perfluoroalkene compounds accompanied by CO2 or SO3 loss.

Summary: The study determined the concentrations of 28 novel and legacy PFASs in wastewater from 77 industrial plants in Korea's largest industrial complex. Only 19 and nine target PFASs were detected in untreated industrial wastewater and river water, respectively. Efforts to reduce the use of Perfluorooctane sulfonate (PFOS) have resulted in its replacement by PFASs with fewer than seven carbon atoms in both industrial wastewater and river water.

Summary: Poly- and perfluoroalkyl substances (PFASs) are anthropogenic chemicals with a fluorinated carbon chain and have gained global attention due to their durability, bioaccumulation potential, and negative impacts on living organisms. The negative impacts of PFASs on aquatic ecosystems are concerning due to their widespread use and constant leakage into the water environment. PFASs can alter the bioaccumulation and toxicity of certain substances, causing a variety of negative consequences in aquatic organisms. PFAS bioaccumulation affects the composition of the intestinal microbiota, which is related to the well-being of the host. PFASs act as endocrine disruptors and can result in dysbiosis of gut microbes and other health repercussions.

Summary: Rapidsmall-scale column tests (RSSCTs) are often usedto evaluate the efficacy of adsorption media for removing perfluoroalkyl acids (PFAAs) from impacted waters. In this study, bench-scale column experiments were conducted to determine the scaling relationship needed to design RSSCTs using Fluoro-Sorb (FS) and compare its effectiveness to granular activated carbon (GAC) and anion exchange resin (AER). The results showed that FS outperformed GAC and AER in removing long-chained PFAAs, but slight changes in chloride to sulfate mass ratio (CSMR) and high pH excursions were observed, emphasizing the importance of proper monitoring to avoid unwanted changes in water quality immediately after FS startup.

Summary: This study evaluated and compared the adsorption of PFASs in contaminated groundwater using granular activated carbon (GAC) and anion exchange resins (AER). The results showed that AERs adsorbed 6-7 times more PFASs than GAC based on media mass or volume. However, when considering the same flowrate, AERs performed similarly to GAC for PFCAs and better for PFSAs. The study also assessed the operational costs of both treatment methods and found that AER and GAC could have similar costs if the ratio of AER to GAC unit media costs was around 3.5.

Summary: This study proposes a method for efficiently removing PFASs from wastewater using excess sludge from an on-site leachate treatment plant. The results show that denitrifying sludge has higher hydrophobicity and specific surface area, enhancing the adsorption capacity of PFASs. Kinetic and isotherm simulations indicate that the adsorption process is efficient and controlled by surface and intraparticle diffusion. The findings of this study contribute to understanding the recycling mechanisms of excess sludge.

Summary: This study investigated the bioaccumulation and fractionation of 11 PFAAs along an aquatic food chain. The results showed that shorter chain PFAAs had lower proportions in organisms compared to exposure water, while longer chain PFAAs had higher proportions. Predation promoted these fractionation differences, with shorter chain PFAAs being replaced by their longer chain analogues. This study highlights the importance of considering fractionation in studying the environmental behaviors and ecological risks of multiple PFAAs.

Summary: In this study, it was found that warming increases the bioaccumulation of per- and polyfluoroalkyl substances (PFAS) in pelagic organisms due to increased water concentrations. However, warming did not significantly affect PFAS accumulation in benthic organisms, except for certain types, which was consistent with declined sediment concentrations. The findings highlight the importance of considering the media-specific effects of temperature on PFAS concentrations in ecological risk assessments under climate change.

Summary: This study found that electrical conductivity is a reliable indicator for assessing the effect of land use types on stream N2O concentrations. It reflects the different levels of N2O concentration and flux in streams across different land uses. Higher electrical conductivity is associated with higher carbon and nutrient levels, as well as abundance of N2O-producing microbes. Electrical conductivity also has the potential to indicate the magnitude of exogenous N2O input across different land uses.

Summary: The influence of light irradiance on N2O emissions in river systems was studied. It was found that light inhibited N2O emissions in the ammonium system and significantly reduced N2O emissions in the nitrate system. Higher light conditions in the nitrate system led to increased N2O reduction and decreased N2O production, resulting in lower N2O emissions.

Summary: This study investigated the bioaccumulation of polycyclic aromatic hydrocarbons (PAHs) in different tissues of zebrafish. It was found that there was variation in the concentrations of PAHs in different tissues, with the highest concentration observed in the skin and the lowest concentration in the fish muscle. The distribution of PAHs was related to lipid content in the tissues, but this correlation was not significant. The study also demonstrated that the physiological based toxicokinetic (PBTK) model could accurately predict PAH concentrations in different fish tissues.

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.

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.
