Summary: The study investigates the adsorption of PFAS compounds on commercial Douglas fir biochar and its magnetic Fe3O4-containing analogue. The results show that both BC and Fe3O4/BC have a high adsorption capacity for PFOS and PFOA, and the adsorption process is driven by hydrophobic and electrostatic interactions. The adsorbents can effectively reduce the PFAS concentrations in water to below the detection limits, approaching the EPA advisory limits. Methanol can be used for successful regeneration of the adsorbents.

Summary: The study investigated the pH-dependent soil-water partitioning of six perfluoroalkyl substances (PFASs) in 11 temperate mineral soils and found that PFAS sorption was positively related to perfluorocarbon chain length and inversely related to solution pH. Organic carbon alone was a poor predictor of PFAS partitioning, and additional factors such as Fe/Al (hydr) oxides and soil texture (silt + clay) played a role. A model based on soil organic matter charge underestimated PFAS sorption. This research highlights the need for further understanding of PFAS behavior and impact in soils.

Summary: Human land use can lead to modifications of soils in small areas, and the legacy effects of past land use are abundant in forests. Relict charcoal hearth (RCH) soils are a widespread example of such legacy soils, with distinct differences from surrounding forest soils in stratigraphy and properties, characterized by a technogenic substrate layer with high charcoal content. RCH soils can significantly contribute to forest soil organic matter stocks, but their distribution and impacts vary across scales, emphasizing the importance of considering land use legacy effects in ecosystem assessment and soil mapping.

Summary: The removal of phosphorus (P) is crucial for protecting the environment. This study investigated the mechanism of P removal by La-containing materials and evaluated the effectiveness of a new material, La-2(CO3)(3(s)), in removing P from various aqueous systems, including municipal wastewater. The results showed that P removal occurred mainly through the precipitation of LaPO4(s). La-2(CO3)(3(s)) exhibited selective removal of P over other anions and had a relatively low solubility, making it a suitable material for P sequestration. Understanding the mechanism of P removal and finding effective materials are important for mitigating eutrophication.

Summary: This study investigates the transformation mechanisms of dissolved inorganic nitrogen (DIN) under hydrodynamic turbulence. Field investigation reveals that NH+4 concentrations are lower in flood seasons compared to drought seasons, while laboratory results demonstrate that limitation of dissolved oxygen (DO) causes inactive nitrification and active denitrification in sediment. Turbulence decreases NH4+ and NO2- concentrations, but increases NO(3 )(-)and total DIN concentrations in the overlying water.

Summary: Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are anthropogenic chemicals that are widely used, but some have been shown to have negative impacts on human health and the environment. The fate of PFAS in the environment is influenced by physical, chemical, and biological processes, with microbial communities known to generate low-molecular-weight PFAS metabolites. This study confirms the ability of acyl-CoA synthetase to catalyze the formation of PFAS-CoA adducts, providing evidence for enzymatic pathways in microbial PFAS metabolism.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
