Summary: Exposure to per- and polyfluoroalkyl substances (PFASs) in preconception women varies widely, with PFOA and PFOS being dominant. The exposure is significantly associated with demographic characteristics and dietary habits, but these factors can only explain a relatively small proportion of PFAS concentration variations. Further exploration of critical factors beyond diet and demographics is necessary for understanding and mitigating preconceptional PFAS exposure.

Summary: Ingestion of lead-based ammunition is a leading cause of bald eagle mortality, primarily from unretrieved carrion contaminated with lead. A model with differential equations describes the dynamics of contaminated carrion and eagles' progression through lead poisoning stages. Sensitivity analysis shows that the bald eagle population in the Great Lakes region depends on the rate of entry of contaminated carrion, and finding a substitute for lead cartridges is the most effective measure to reduce financial costs associated with this issue.

Summary: The study found that PFAS concentrations in house dust from Guangzhou were relatively high compared to other regions, exhibiting a specific composition pattern. Renovation history was identified as a significant factor influencing PFAS concentrations, with low exposure risks mainly from dust ingestion and dermal contact. Nevertheless, the potential risks from indoor PFAS exposure, including chemical-specific effects and mixture effects, should not be underestimated.

Summary: Temporal and spatial trends of 15 per- and polyfluoroalkyl substances (PFAS) were determined in white-tailed sea eagle (WTSE) eggs from Sweden between 1969 and 2021. PFAS concentrations generally increased until the 1990s-2010 and then plateaued or declined. Coastal populations had higher PFAS concentrations, possibly due to differences in diet and proximity to densely populated areas. Most extractable organofluorine in WTSE eggs consisted of known PFAS, with low levels of novel substances.

Summary: Rice plants provide staple food for 3 billion people worldwide. This study investigates the environmental fate and behavior of chlorinated paraffins (CPs), a high-volume production emerging contaminant, in the paddy ecosystem. The results indicate that short-chain and medium-chain CPs can be translocated from soils to paddy tissue, posing an increased bioaccumulative potential. The risk evaluation suggests that the intake of medium-chain CPs and the associated risks dominate the total exposure to CPs through rice ingestion. This is the first report on the occurrence, fate, and risk assessment of all CPs classes in paddy ecosystems.

Summary: Microplastic pollution is a global concern. This study investigates the sorption of various organic contaminants on HDPE and PVC microplastics under saline conditions. The sorption coefficients varied for different chemicals and microplastics, and were largely influenced by hydrophobicity. Particle size did not significantly affect sorption isotherms but influenced equilibrium time and maximum sorption, likely due to surface area. Biofilms on HDPE microplastics enhanced contaminant sorption capacity. These findings provide new insights into chemical-microplastic interactions in marine environments.

Summary: This review summarizes the current knowledge of amino antioxidants (AAOs) including their production and usage, environmental occurrence, bioavailability, human exposure, and aquatic toxicity. Previous studies have shown widespread distribution of AAOs in various environmental matrixes, and their degradation products have also been detected at high levels. Human exposure to AAOs primarily occurs through dust ingestion and air inhalation, while limited studies have been conducted on other exposure pathways and AAO burdens in human tissue. AAOs have shown toxic effects on aquatic organisms, and the toxicity of degradation products differs from their precursors. Future research should focus on elucidating AAO exposure in humans and the health risks associated with it, as well as studying the effects of complex mixtures of these chemicals.

Summary: This study investigated the spatial distribution of 15 Amino accelerators and antioxidants (AAL/Os) and 5 AAO transformation products (AAOTPs) in sediments from the Dong Nai River System (DNRS) in Vietnam. The results showed higher levels of these compounds in downstream and primary tributary sediments, suggesting their cumulative sedimentation towards the estuarine region. The characteristics of the sediments, such as total organic carbon (TOC) content and grain sizes, were significantly correlated with the burdens of these compounds, indicating their preferential partitioning into fine and TOC-rich matter. This research provides valuable insights into the environmental behavior of AAL/Os and AAOTPs in Asian aquatic systems and highlights the need for further evaluation of their impacts on wildlife and public health.

Summary: Distinct hydrodynamic conditions in estuaries create a hotspot of plastic and additive pollution, but the impact of specific estuarine weathering on additive migration remains unclear. We simulated estuarine conditions to investigate the release of migrated plastic additives (MPAs) from different plastics. Wave actions significantly enhanced the leaching of MPAs, with more additives detected in plastic bag leachates. Nonionic surfactants, octylphenol polyethoxylates (OPEOn), showed high toxicity in packaging bag leachates, affecting zebrafish hatching and causing cardiovascular disorders. Overall, plastic leachates, especially from plastic bags, pose significant risks to estuarine ecosystems.

Summary: A comprehensive analysis of Canadian food packaging used for fast foods (n = 42) revealed that 55% of the samples contained <3580, 19% contained 3580-10,800, and 26% > 10,800 μg F/m(2) of per- and polyfluoroalkyl substances (PFAS). Targeted analysis of samples with high total F identified 4-15 individual PFAS in each sample, with 6:2 fluorotelomer methacrylate (FTMAc) and 6:2 fluorotelomer alcohol (FTOH) being the most dominant. Nontargeted analysis detected 22 PFAS from 6 different groups, including degradation products of FTOH. The use of PFAS in food packaging, such as compostable bowls, is a regrettable substitution for single-use plastic food packaging.

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.
