“…PFOA and PFOS distributions appear similar to those observed in other urban/industrialized regions (e.g. (Bečanová et al, 2016;Myers et al, 2012;Zhao et al, 2014), while long-chain PFCAs (especially PFUnDA, PFDoDA, PFTrDA and PFTeDA) display unusually high levels and relative abundances at site R4 and further downstream, as already noted by Dauchy et al (2012) and Munoz et al(2015). 6:2 FTSA is not detected in sediments upstream from site R4, while it is found in most samples collected downstream.…”

“…As shown in Figure 1, a large number of PFCs have been cyclically migrated into the environment, daily necessities, and even people since the beginning of production. Currently, PFCs can be detected in air [28], water [29], sediment [30], and soil [31]. PFCs contamination has spread all over the world in various ecosystems, and they can even be detected in polar ice sheets and animal tissues [32].…”

Perfluorinated compounds (PFCs) are recognized as a new type of refractory organic pollutants. Due to the persistent environmental pollution, bioaccumulation, and biotoxicity of PFCs, they have received extensive attention in recent years. To deal with the environmental risks caused by PFCs, the pollution and distribution of PFCs in the aquatic environment are discussed in detail, mainly for the most widely used PFCs—perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS). The latest progress in the current processing technology of PFOA and PFOS is comprehensively introduced. It includes a variety of physical techniques to remove PFCs such as adsorption and flocculation. It has been confirmed that various adsorbents can play a key role in the enrichment and removal of PFCs through high specific surface area and hydrophobic interaction. In addition, traditional degradation processes are often unsatisfactory for PFCs, prompting the search for more efficient and cost-effective methods, with great progress having been made in advanced oxidation processes (AOPs) based on radical decomposition of pollutants. This review also integrates multiple advanced oxidation processes (AOPs) such as photocatalysis, electrochemical processes, ozone, the Fenton process, and ultrasound. This paper provides an overview of the various PFCs removal techniques and discusses their efficacy. It also explores future possible developments for PFCs elimination technologies for water treatment.

“…Per- and polyfluoroalkyl substances (PFAS) are a diverse group of synthetic organofluorine chemicals that are characterized by the presence of one or more perfluoroalkyl or polyfluoroalkyl groups. Many are amphiphilic, heat resistant, and chemically stable, properties that make them useful for a wide variety of industrial and consumer applications. , High volume production and widespread use of PFAS-containing products, along with global transport of these chemicals through air and water, has led to ubiquitous contamination of indoor and outdoor environments. − Because many PFAS are non-degradable in the environment, or degrade to terminal perfluorinated end products, they persist in the environment and accumulate in biota . Such ubiquity, persistence, high-mobility, and ability to bioaccumulate, combined with the robust evidence of toxicity, necessitates biomonitoring efforts to characterize the exposure and long-term health consequences of PFAS.…”

Central North Carolina (NC) is highly contaminated with per- and polyfluoroalkyl substances (PFAS), in part due to local fluorochemical production. Little is known about the exposure profiles and long-term health impacts for humans and animals that live in nearby communities. In this study, serum PFAS concentrations were determined using liquid chromatography high-resolution mass spectrometry and diagnostic clinical chemistry endpoints were assessed for 31 dogs and 32 horses that reside in Gray’s Creek NC at households with documented PFAS contamination in their drinking water. PFAS were detected in every sample, with 12 of the 20 PFAS detected in ≥50% of samples from each species. The average total PFAS concentrations in horses were lower compared to dogs who had higher concentrations of PFOS (dogs 2.9 ng/mL; horses 1.8 ng/mL), PFHxS (dogs 1.43 ng/mL, horses < LOD), and PFOA (dogs 0.37 ng/mL; horses 0.10 ng/mL). Regression analysis highlighted alkaline phosphatase, glucose, and globulin proteins in dogs and gamma glutamyl transferase in horses as potential biomarkers associated with PFAS exposure. Overall, the results of this study support the utility of companion animal and livestock species as sentinels of PFAS exposure differences inside and outside of the home. As in humans, renal and hepatic health in domestic animals may be sensitive to long-term PFAS exposures.
