Peer Reviewed Research
Carey, G. R., et al. (2024). "Modeling the Influence of Coastal Site Characteristics on PFAS in Situ Remediation." Ground Water.
The potential performance of a hypothetical colloidal-activated carbon (CAC) in situ remedy for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) in groundwater in coastal zones was evaluated using estimated hydrogeologic and geochemical parameters for a coastal site in the United States.
Dong, S., et al. (2024). "Fate and Transformation of 15 Classes of Per- and Polyfluoroalkyl Substances in Aqueous Film-Forming Foam (AFFF)-Amended Soil Microcosms." Environ Sci Technol.
The environmental fate of per- and polyfluoroalkyl substances (PFAS) in aqueous film-forming foams (AFFFs), especially those synthesized by electrochemical fluorination (ECF) processes, remains largely unknown. This study evaluated the transformation of AFFF-derived ECF-based precursors in aerobic soil microcosms amended with a historically used AFFF formulation (3M Light Water(TM)).
Huang, J., et al. (2024). "Enhanced selective removal of PFAS at trace level using quaternized cellulose-functionalized polymer resin: Performance and mechanism." Water Res 272: 122937.
In order to ensure safe water treatment, sorption using quaternary ammonium functionalized strong-base anion exchange resins (SB-AERs) is considered a viable option for treating PFAS when compared to commercialized activated carbon, as SB-AERs can be in situ regenerated with long-term operation capabilities.
Jiang, X., et al. (2024). "Occurrence, Transport, and Full-Scale Adsorptive Removal of PFAS in Electroplating Parks in China." Environ Sci Technol.
The electroplating industry is an important source of per- and polyfluoroalkyl substances (PFAS) contamination, but there is a lack of comprehensive studies on the occurrence, transport, and removal of PFAS in electroplating parks. In this study, we investigated typical electroplating parks in China and conducted the first full-scale removal of PFAS from chromium-plating wastewater using pore-enlarged granular activated carbon (GAC) and hydrophobic anion exchange resin (AER).
Kirkeli, C., et al. (2024). "Target and non-target screening of poly- and perfluoroalkyl substances (PFAS) in fish liver samples from the River Nile in Sudan: A baseline assessment." Mar Pollut Bull 211: 117388.
This study provides the first assessment of PFAS contamination in fish livers from the River Nile in Sudan, using ultra-high-performance liquid chromatography and high-resolution mass spectrometry. Perfluorooctane sulfonate (PFOS), perfluorononanoic acid (PFNA), perfluorodecanoic acid (PFDA), and perfluoroundecanoic acid (PFUnDA) were measured, with fish downstream of Jebel Aulia Dam showing the highest concentrations:
Lejeune, N., et al. (2024). "Associations between prenatal exposure to PFAS and cardiometabolic health in preadolescents." Environ Res: 120607.
The aim of this study was to investigate the associations between prenatal exposure to PFAS and cardiometabolic health parameters at age 12, taking pubertal stage into consideration. METHOD: This study included 394 mother-child pairs enrolled in the PELAGIE mother-child cohort (France). Nine PFAS were measured in umbilical cord blood, and the children attended a clinical examination at age 12.
Litvanová, K., et al. (2024). "Investigation of Real-Time Gaseous Thermal Decomposition Products of Representative Per- and Polyfluoroalkyl Substances (PFAS)." J Am Soc Mass Spectrom.
The thermal decomposition of per- and poly fluoroalkyl substances (PFAS) is poorly understood. Here, we present an innovative, comprehensive analytical method to investigate their thermal decomposition, including perfluorocarboxylic acids (PFCAs), alcohol, sulfonates, and GenX (acid dimer), focusing on identifying their breakdown products.
Pal, D., et al. (2024). "Microplastics in aquatic systems: A comprehensive review of its distribution, environmental interactions, and health risks." Environ Sci Pollut Res Int.
This review consolidates knowledge on MPs' occurrence, transformation, pollutant interactions, and methodologies for sampling and analysis, emphasizing advancements in spectroscopy and imaging techniques to improve MP detection in aquatic environments.
Randazzo, A., et al. (2024). "Perfluoroalkyl substances (PFASs) in groundwater and surface water in the Turin metropolitan area (Italy): An attempt to unravel potential point sources and compliance with environmental/drinking water quality standards." Sci Total Environ 958: 177973.
The study investigated the contribution of five potential point source categories on the occurrence of 19 highly hazardous perfluoroalkyl substances (PFASs) in freshwater from the Turin metropolitan area (Italy) and assessed the quality of groundwater and surface water in compliance with European and Italian guidelines.
Sassano, M., et al. (2024). "Exposure to Per- and Poly-fluoroalkyl Substances and Lung, Head and Neck, and Thyroid Cancer: A Systematic Review and Meta-Analysis." Environ Res: 120606.
Recent evidence suggests that exposure to per- and polyfluoroalkyl substances (PFAS) may increase the risk of different cancer types, such as kidney and testicular cancers. Instead, evidence for lung, head and neck, and thyroid cancer is sparse. Hence, we aimed to summarize available literature on the topic.
Wang, F., et al. (2024). "Serum metabolome associated with novel and legacy per- and polyfluoroalkyl substances exposure and thyroid cancer risk: A multi-module integrated analysis based on machine learning." Environ Int 195: 109203.
BACKGROUND: Exposure to per- and polyfluoroalkyl substances (PFAS) may linked to thyroid cancer (TC) risk, but inconsistent findings and a lack of studies on mixed exposures exist, especially regarding novel PFAS compounds. Additionally, little is known about the potential mechanisms underlying the association.
Wang, K., et al. (2024). "Unravel the in-Source Fragmentation Patterns of Per- and Polyfluoroalkyl Substances during Analysis by LC-ESI-HRMS." Environ Sci Technol.
In-source fragmentation (ISF) was inevitable during electrospray ionization (ESI) of per- and polyfluoroalkyl substances (PFAS) when analyzed by liquid chromatography coupled with mass spectrometry (LC-MS), resulting in reduced response of molecular ions and misannotation of MS features. Herein, we analyzed 82 PFAS across 12 classes to systematically identify the structures with ISF potentials and reveal the fragmentation pathways.
Zhang, S., et al. (2024). "Per- and poly-fluoroalkyl substances exposure and risk of gastrointestinal cancers: a systematic review and meta-analysis." Eur J Cancer Prev.
This review aims to investigate the link between PFAS exposure and the risks of other cancers, including gastrointestinal cancers such as esophageal, gastric, colorectal, and pancreatic cancer. METHODS: We conducted a systematic review of literature from the International Agency for Research on Cancer Monographs, Agency for Toxic Substances and Disease Registry documents, and PubMed (up to January 2024) focusing on the association between PFAS exposure and gastrointestinal cancers.
