Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

Journal of Applied Toxicology, EarlyView.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

Biodegradation of fluorinated octanoic acids in an O2-based membrane biofilm reactor

Water Research X
Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants due to their widespread use and recalcitrance to degradation. Aerobic bioreactors provide a possible path for further defluorination and mineralization of reductively ...

Perfluorooctanoic Acid and Cardiovascular Disease in US Adults [PDF]

Archives of Internal Medicine, 2012
Cardiovascular disease (CVD) is a major public health problem. Identifying novel risk factors for CVD, including widely prevalent environmental exposures, is therefore important. Perfluorooctanoic acid (PFOA) is a manmade chemical used in the manufacture of common household consumer products.

PFAS properties and destruction methods: A focus on enzymatic degradation

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Per‐ and polyfluoroalkyl substances (PFAS) are known as ‘forever’ chemicals and have lasting detrimental impact on the environment and living organisms. To understand PFAS molecules better, this review begins with an overview of PFAS definition, classifications and applications, and then provides a comprehensive summary and critical analysis ...

Astaxanthin reduces perfluorooctanoic acid cytotoxicity in Saccharomyces cerevisiae [PDF]

Toxicology Research, 2019
Abstract Perfluorooctanoic acid (PFA) has been identified as an environmental contaminant of high concern for human health. In this study, we demonstrated that PFA induces a dose (0 to 1.5 mM) dependent cytotoxicity in S. cerevisiae cells which can be rescued by astaxanthin.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

PFAS Removal by Anion‐Exchange Block Copolymer Membranes Featuring Highly Ordered Alternating Gyroid Nanochannels

Journal of Polymer Science, EarlyView.
Engineering positively charged alternating gyroid nanochannels in block copolymer membranes provides a powerful tool for efficient PFAS removal. ABSTRACT Ion‐exchange resins (IERs) can effectively remove per‐ and polyfluorinated alkyl substances (PFAS) from water through electrostatic interactions between the negatively charged PFAS and the positively ...

PFOA Exposure Elicits Quantitative Lipidomic Changes in the Pancreas in a Mouse Model of Pancreatic Cancer

Environmental Toxicology, EarlyView.
ABSTRACT Pancreatic cancer is the fourth leading cause of cancer deaths in the US and predicted to rise to second by 2030. Several risk factors have been identified as potential contributors to pancreatic cancer development including lifestyle factors and long‐term exposure to occupational and environmental carcinogens.
