Summary: A dual-functional modification of MIL-101(Cr) was successfully introduced for the efficient enrichment of PFASs, enabling ultrasensitive quantitative analysis of nine selected PFASs using UHPLC-MS/MS. The designed solid extractant showed excellent performance in selective enrichment and analysis of PFASs at trace concentrations in real applications.

Summary: Eighteen PFASs were studied in surface waters of four river basins in Portugal. All sampling sites showed contamination in at least one season. The most frequent PFASs varied between dry and wet seasons. PFOS and PFOA were the most frequent in dry season, while PFOA and PFBS were the most frequent in wet season. The potential environmental risks of PFASs were evaluated based on risk quotient (RQ), showing generally low risk except for PFTeA which posed high risks for fish and daphnids.

Summary: The case-control study revealed a positive association between PFASs exposure and COVID-19 susceptibility, with PFASs-associated metabolites implicated in mitochondrial function and immune activity. Larger studies are needed to confirm these findings and further understand the impact of PFASs exposure on the pathogenesis of SARS-CoV2 infection.

Summary: Electrochemical degradation using boron-doped diamond (BDD) electrodes has been proven to be an effective method for treating water contaminated with per- and poly-fluoroalkyl substances (PFAS). Factors such as current density and treatment time were found to significantly impact the degradation efficiency of PFAS, particularly perfluorooctanoic acid (PFOA). High concentrations of organic carbon and chloride in wastewater samples were identified as important factors affecting the efficiency of PFAS electrochemical degradation. Increasing treatment time is recommended to effectively degrade PFAS in both water and wastewater samples.

Summary: The removal of per- and poly-fluoroalkyl substances (PFASs) from water using membrane-based techniques has garnered increasing attention worldwide due to the widespread presence and high toxicity of these compounds. Different membrane technologies, such as direct filtration, adsorption-based membranes, and hybrid processes, have been developed to address the risk of exposure to PFASs and their environmental dispersion. The performance, treatment efficiencies, and mechanisms of these membrane processes for PFASs removal are analyzed, with a focus on the advantages, limitations, challenges, and prospects of applying these technologies in a practical and sustainable manner.

Summary: PFASs are synthetic organofluorine aliphatic compounds extensively used since the 1940s, but they are non-biodegradable and extremely toxic to the environment. Recent studies have shown that wetlands can serve as a nature-based solution for PFASs removal through the plant-microbe interplay. Understanding the role of plants, microbes, and their interaction is crucial for designing an effective passive treatment wetland system.

Summary: This study analyzed 32 PFASs in 49 Tawny Owl body feathers collected in Trondelag, Norway from 2017 to 2020. It was found that 30 PFASs were detected in at least one feather, with concentrations ranging from 31 to 203 ng/g. PFHpA and FOSAA had the highest concentrations. PFOS, a banned substance in Norway, was found in all samples. The sum concentration of PFASs slightly increased over the sampling years. Tawny Owl feathers can be used as a potential alternative matrix for future biomonitoring studies.

Summary: This study collected rainwater samples from Chongqing, China, over four seasons and analyzed them for 17 PFASs. The results showed that paper packaging production and AFFF usage were the major sources of PFASs, with distinct seasonal variations and wet deposition being the main pathway. This study provides important information for understanding PFASs occurrence and atmospheric wet deposition in Chongqing and other urban centers in China.

Summary: Sixteen paired surface sediment samples were collected from upstream to downstream of the water-level-fluctuation zone of Three Gorges Reservoir in China. The concentration of PFASs in the sediments was influenced more by anthropogenic activities than physicochemical parameters, with PFOA-based products identified as the major source. The study provides basic data on PFASs in surface sediments and highlights the important transport of PFASs from upstream to downstream reaches for further research.

Summary: The distribution of PFASs in the open oceans is influenced by land-based emissions and historical residues, with PFOA mainly derived from land sources and PFOS mainly from historical residues. The new emerging compound 6:2 Cl-PFESA was found in higher concentrations near Australia. Different regions showed different sources of PFASs, with the Southern Ocean primarily influenced by atmospheric input and the Northwest Pacific Ocean and Eastern Indian Ocean mainly originating from land sources.

Summary: This study aimed to develop a suitable extraction methodology for the analysis of PFAS in asphalt materials and optimize extraction solvent composition. The results showed that methanol-based extractants performed best and the timing of stable isotope addition did not affect the accuracy and precision of PFAS recoveries.

Summary: The European Food Safety Authority's downward revision of the Health-based Guidance Value for bisphenol A (BPA) has led to disagreements with other regulatory agencies, particularly the German Federal Institute for Risk Assessment. The differing views between EFSA and BfR are driven by their respective selection of endpoints and study evaluation systems, as well as their acceptance or refusal of immunotoxic effects as a basis for establishing a Health-based Guidance Value.

Summary: The aim of this study was to assess the exposure of e-waste workers to phthalates and alternative plasticizers. The results showed that e-waste workers had higher urinary concentrations of phthalates and metabolites compared to non-occupationally exposed controls. However, no significant differences were found between pre-and post-shift concentrations in the e-waste workers.
