The net present cost to remove PFAS from landfill liquid waste using reverse osmosis was estimated to be between $392-578 million USD for a network of 111 landfills.

Change in global PFAS Cycling as a response of permafrost degradation to climate change

4 Jan 2022 | J. Hazard. Mater. Adv.

Permafrost is a likely source of PFAS pollution due to the freeze-thaw process, which changes the spatial distribution of different compounds of PFAS in permafrost depth.

Combined Use of Total Fluorine and Oxidative Fingerprinting for Quantitative Determination of Side-Chain Fluorinated Polymers in Textiles

3 Jan 2022 | ES&T

A method was developed to determine the side-chain fluorinated polymer concentrations in terms of the side chain mass, as opposed to fluorine equivalents, facilitating the estimation of the structure and quantity of PFAA degradation products in medical textiles.

Insufficient evidence for the existence of natural trifluoroacetic acid

3 Jan 2022 | Environ. Sci.: Processes Impacts

The authors argue that there is not sufficient evidence that TFA occurs naturally, contrary to previous claims.

21 Dec 2021 | Environ Sci Technol

Seaspray aerosols may be a source of PFAAs to the air, where they can undergo long-distance transportation.

Immunotoxicity of PFOA to the Marine Bivalve Species Ruditapes philippinarum

21 Dec 2021 | Environ Toxicol Chem

PFOA was found to be immunotoxic to saltwater clams, at different levels highlighting the potentially detrimental effects of PFAS contamination in marine ecosystems.

Environmental pollutant exposure associated with altered early-life gut microbiome: Results from a birth cohort study

20 Dec 2021 | Environ Res

Prenatal exposure to PFAS is associated with alterations to gut microbiome development in infants, with larger effects in breastfed and cesarean-section-born babies.

Association between maternal serum concentration of perfluoroalkyl substances (PFASs) at delivery and acute infectious diseases in infancy

20 Dec 2021 | Chemosphere

Prenatal exposure to PFAS was associated with increased risks of diarrhea during the first year of life, and these effects were stronger among breastfed infants.

Distribution, sources, and dietetic-related health risk assessment of perfluoroalkyl acids (PFAAs) in the agricultural environment of an industrial-agricultural interaction region (IAIR), Changshu, East China

20 Dec 2021 | Sci Total Environ

Textiles and food industries may contribute to PFAAs in agricultural environments, which can lead to high PFAS contamination in local fish and vegetables.

Development and validation of an LC-MS/MS method for the quantitation of 30 legacy and emerging per- and polyfluoroalkyl substances (PFASs) in human plasma, including HFPO-DA, DONA, and cC6O4

20 Dec 2021 | Anal Bioanal Chem
