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: The extensive use of per- and polyfluoroalkyl substances (PFASs) in various industries and daily-life products has made them common contaminants in soil and water. Although several remediation strategies are available, strong ionic interactions between PFASs and soil constituents hinder the effectiveness of these technologies. Phytoremediation appears to be a potential technology for cleaning up PFAS-contaminated soils, but there are limitations in practical applications.

Summary: Per- and polyfluoroalkyl substances (PFAS) are widely used in various commercial products and some of them are known to accumulate in aquatic species. A literature search was conducted to understand the relationship between sediments and aquatic species, and data on biota-sediment accumulation factors (BSAFs) for different taxonomic classes were compiled. Among the taxonomic classes, Teleostei had the highest BSAFs, while Magnoliopsida and Bivalvia had the lowest BSAFs. Laboratory-measured BSAFs were consistently higher than field-measured BSAFs.

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 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: A wide range of chemicals in drinking water and urine samples were analyzed through target and non-target screening to estimate human exposure. PFAS, bisphenol A, and nonylphenol were detected in tap water and urine samples, and LC-HRMS revealed the presence of pharmaceuticals and industrial chemicals. Reverse osmosis effectively removed PFAS, while activated carbon filters did not. These findings are important for exposure science and monitoring drinking water contaminants.

Summary: This study created two wristbands to monitor personal exposure to PFASs. The results showed that HFPO-DA was the predominant PFASs in the wristbands, with higher concentrations found in the TPU wristbands. The gender and grade of students had moderate effects on PFASs distribution in the wristbands. The study suggests that HDPE and TPU wristbands can be effective tools for monitoring personal PFAS exposure.

Summary: The effective enrichment of perfluoroalkyl acids (PFAAs) in sea spray aerosols demonstrated in laboratory studies suggests that sea spray aerosols could be a potential source of PFAAs to the atmosphere. A field study in coastal areas of Norway found significant correlations between the sea spray aerosol tracer ion Na+ and PFAA concentrations, indicating sea spray aerosols as an important source of atmospheric PFAAs in coastal regions. The correlations were stronger in samples from Andoya, which is closer to open water and further away from urban areas compared to Birkenes.

Summary: The purpose of the study is to investigate whether changes in the legal text and information required in an application for authorisation are needed to implement the essential-use concept. The results suggest that no fundamental changes are needed and applicants already provide sufficient information. If the risk related to the use is adequately controlled, it is not legally justified for the European Commission to refuse authorisation by arguing non-essential use.

Summary: PFAAs are widespread in the oceans, but there is limited knowledge about their vertical distribution and fate. This study measured the concentrations of PFAAs in surface and deep ocean waters and found that PFAA input comes from the Mediterranean Sea and the English Channel. Higher PFAA levels were observed at the eastern edge of the Northern Atlantic Subtropical Gyre, indicating the accumulation of persistent contaminants in ocean gyres. PFAA concentrations generally decreased with distance from the coast and increasing depth, and longer-chain PFAAs were more prevalent in intermediate depths due to their stronger sorption to organic matter.

Summary: Recycling of lithium-ion batteries (LIBs) is vital for meeting the increasing demand for metals and achieving a sustainable circular economy. However, there is limited knowledge about the environmental risks associated with LIB recycling, particularly the emission of persistent fluorinated substances. This study provides an overview of the use of fluorinated substances in LIBs and highlights the potential formation and release of persistent fluorinated substances during the recycling process. It calls for further investigation and suggests the substitution of PFAS-based materials or changes in process conditions to prevent the formation and emission of persistent fluorinated substances.
