Summary: Water-soluble polymers (WSPs) such as polyethylene oxide (PEO) are widely used and released into the aquatic environment, but there is a lack of analytical methods to study their occurrence. This study developed a method using size exclusion chromatography and mass spectrometry to quantify PEO and its derivatives in wastewater treatment plants (WWTPs) and surface water. The concentrations of PEO detected were relatively high, indicating potential risks in the aquatic environment. This method can help assess the burden and risk of high production volume chemicals like PEO.

Summary: Dissolved organic matter (DOM) driven-photochemical processes are important in the redox cycling of trace metals and attenuation of organic contaminants in estuarine and coastal ecosystems. This study examined the effect of Cu on the photosensitized degradation of seven target contaminants (TCs) under typical pH and salt conditions. The results showed that trace amounts of Cu(II) strongly inhibit the degradation of TCs in solutions containing certain compounds. The inhibitory effect of Cu decreases with increasing Cl concentration. Overall, Cu has a significant impact on the degradation of TCs. Rating: 8/10.

Summary: Aqueous solubility is an important environmental property that can be used to assess the hydrophobicity, ecological risk, and toxicity of organic pollutants. However, there is a lack of standard procedures for evaluating prediction models. In this study, the CRITIC-TOPSIS comprehensive assessment method was proposed and applied to evaluate 39 models developed using different algorithms and descriptor screening methods. The MLR-1, XGB-1, DNN-1, and kNN-1 models showed better predictive accuracy and external competitiveness compared to other models in each group. The XGB model based on SRM (XGB-1, C=0.599) was selected as the optimal pathway for predicting aqueous solubility.

Summary: Plastics degrade in the natural environment due to irradiation, impacting surface properties and pollutant migration behavior. Limited research exists on sorption/desorption behavior of organic pollutants on aged plastics. This study analyzed various commercial plastics and their sorption/release behavior for bisphenols. Results showed oxidization and surface cracks after irradiation, with sorption dominated by hydrophobicity and other factors including electrostatic force and bonding interactions. Desorption kinetics indicated faster release after aging, with hydrophobicity playing a role. Salinity and dissolved organic matter enhanced sorption capacity, while increased temperature promoted bisphenol release from both fresh and aged plastics.

Summary: This study used an in situ tool, diffusive gradients in thin films (DGT), to investigate the distribution and exchange kinetics of five typical PFAS in four soils. The results showed a nonlinear relationship between PFAS masses in DGT and time, indicating that PFAS were partially supplied by the solid phase in all soils. A dynamic model called DGT-induced fluxes in soils/sediments (DIFS) was used to interpret the results and determine the distribution coefficients for the labile fraction (Kdl), response time (tc), and adsorption/desorption rates (k1 and k-1). The findings suggest that the availability of PFAS in soils is controlled by Kdl, while the release of PFAS from soils may be kinetically constrained, especially for more hydrophilic PFAS.

Summary: The occurrence, fate, removal, and ecological risks of various emerging contaminants (ECs) were investigated in two textile wastewater treatment plants (WWTPs) in a large textile industrial park in Southwest China. A total of 50 ECs were identified, with phthalate esters (PAEs), endocrine disrupting chemicals (EDCs), and per- and polyfluoroalkyl substances (PFAS) being the most dominant. The WWTPs effectively removed 63-69% of the detected ECs, with removal efficiencies exceeding 80%. Fenton processing showed enhanced removal efficiencies for long-chain PFAS. The PAEs and EDCs posed medium-to-high risks to aquatic organisms and were identified as priority ECs.

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.
