Developing a QSPR Model of Organic Carbon Normalized Sorption Coefficients of Perfluorinated and Polyfluoroalkyl Substances

Molecules, 2022
Perfluorinated and polyfluoroalkyl substances (PFASs) are known for their long-distance migration, bioaccumulation, and toxicity. The transport of PFASs in the environment has been a source of increasing concerned.

Unveiling the hidden threat: spatiotemporal trends and source apportionments of per-and polyfluorinated alkyl substances in wastewater treatment plants in South Africa

Water Science and Technology
At least 11 per-and polyfluorinated alkyl substances (PFASs) were more prevalent during the dry season, whereas only PFBA, L-PFBS, L-PFOS, and PFOA were prevalent during the wet season in 11 WWTPs.

Occurrence, Sources, and Prioritization of Per- and Polyfluoroalkyl Substances (PFASs) in Drinking Water from Yangtze River Delta, China: Focusing on Emerging PFASs

Molecules
As regulations ban legacy PFASs, many emerging PFASs are being developed, leading to their release into the aquatic environment and drinking water. However, research studies on these emerging PFASs in drinking water are limited, and current standards ...

Increasing perfluoroalkyl substances and ecological process from the Yongding Watershed to the Guanting Reservoir in the Olympic host cities, China

Environment International, 2019
Perfluoroalkyl substances (PFASs) have raised great attention, particularly in regions of rapid urbanization. Zhangjiakou and Beijing will jointly host the Winter Olympic Games in 2022, which will likely increase local PFASs pollution and their ...

Redox-active rGO-nZVI nanohybrid-catalyzed chain shortening of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS)

Journal of Hazardous Materials Letters, 2021
Per- and polyfluoroalkyl substances (PFASs) are exceptionally stable chemicals due to their strong CF bonds. Nanoscale zero-valent iron (nZVI) particles have the potential to remove and degrade PFASs through redox activity.

BODIPY‐based J‐aggregates: From supramolecular chemistry to NIR bioimaging and phototherapies

Bulletin of the Korean Chemical Society, EarlyView.
BODIPY dyes form ordered J‐aggregates through controlled supramolecular self‐assembly, producing narrow, red‐shifted absorption bands with small Stokes shifts. This review highlights design strategies governing J‐aggregation, structure–property relationships, and applications in sensing, bioimaging, and phototherapy, guiding functional BODIPY‐based ...

Association between ρE3 PUFAs and PFAS Bioaccumulation in Benthic Animals across a Watershed

Journal of Water and Environment Technology
The widespread presence of per- and polyfluoroalkyl substances (PFASs) in aquatic environments poses significant risks to aquatic food webs. As primary consumers, benthic animals not only transfer energy through food chains but also facilitate PFASs ...

Association of Perfluoroalkyl and polyfluoroalkyl substances (PFASs) exposures and the risk of systemic lupus erythematosus: a case–control study in China

Environmental Health, 2023
Perfluoroalkyl and polyfluoroalkyl substances (PFASs) may have a role in impaired health. However, the data on the association between PFASs and Systemic lupus erythematosus (SLE) have been limited.
