Per- and polyfluoroalkyl substances (PFAS) are a large group of engineered chemicals that have been widely used in industrial production. PFAS have drawn increasing attention due to their frequent occurrence in the aquatic environment and their toxicity to animals and humans. Developing effective and efficient detection and remediation methods for PFAS in aquatic systems is critical to mitigate ongoing exposure and promote water reuse. Adsorption-based removal is the most common method for PFAS remediation since it avoids hazardous byproducts; in situ sensing technology is a promising approach for PFAS monitoring due to its fast response, easy operation, and portability. This review summarizes current materials and devices that have been demonstrated for PFAS adsorption and sensing. Selectivity, the key factor underlying both sensor and sorbent performance, is discussed by exploring the interactions between PFAS and various probes. Examples of selective probes will be presented and classified by fluorinated groups, cationic groups, and cavitary groups, and their synergistic effects will also be analyzed. This review aims to provide guidance and implication for future material design toward more selective and effective PFAS sensors and sorbents.

Background: Hexafluoropropylene oxide dimer acid (GenX), a substitute for per- and polyfluoroalkyl substances, has been widely detected in various environmental matrices and foods recently, attracting great attention. However, a systematic characterization of its reproductive toxicity is still missing. This study aims to explore the male reproductive toxicity caused by GenX exposure and the potential cellular and molecular regulatory mechanisms behind it.

Per- and polyfluoroalkyl substances (PFAS) are persistent organic pollutants (POPs) with toxicity, chemical stability, and long-range transport potential. The transport and accumulation mechanisms of PFAS in specific or typical lakes have been reported. In the wake of global PFAS pollution, it is more important to unravel the distribution patterns of PFAS across larger-scale, multi-lake systems.

Per- and polyfluoroalkyl substances (PFAS) are recalcitrant contaminants of emerging concern. Research efforts have been dedicated to PFAS microbial biotransformation in the hopes of developing treatment technologies using microorganisms as catalysts. Here, we performed a meta-analysis by extracting and standardizing quantitative data from 97 microbial PFAS biotransformation studies and comparing outcomes statistical tests.

Objectives: to evaluate the association between exposure to per- and polyfluoroalkyl substances (PFAS) and semen quality in young adulthood, with particular attention to different exposure metrics: serum and seminal concentrations of perfluorooctanoic acid (PFOA) and perfluorosulfonic acid (PFOS), foetal exposure, duration of exposure.
Design: cross-sectional study.
Setting And Participants: 1,000 subjects aged 18-35 years residing in the Veneto area with water contamination by PFAS, enrolled in the period 2022-2023; this interim analysis involves 507 subjects out of the 1,000 enrolled.

Per- and Poly-fluoroalkyl substances (PFASs) are among the substances that have been widely employed across the world due to their distinct features. These chemicals' great stability in the environment and capacity to be released from consumer goods have demonstrated their existence in all matrices. Additionally, the world's attention has been drawn to these substances' direct relation to human health in recent years.
