Per-and Polyfluorinated Alkyl Substances (PFAS) Cycling within Michigan: Contaminated Sites, Landfills and Wastewater Treatment Plants
4 Jan 2022 | Water Research
Analysis of PFAS in Michigan waste found that landfill leachate is a primary source of PFAS to WWTPs, and treatment can increase PFAS concentrations up to 19x, yet long-chain PFAS like PFOA concentrate in biosolids.
Prenatal and postnatal exposure to emerging and legacy per-/polyfluoroalkyl substances: Levels and transfer in maternal serum, cord serum, and breast milk
4 Jan 2022 | Sci Total Environ
Most PFAS transfer more efficiently via the placenta than breastfeeding, but the one-month postnatal exposure to PFAS via breastfeeding was higher than prenatal exposure in utero.
Absorption and elimination of per and poly-fluoroalkyl substances substitutes in salmonid species after pre-fertilization exposure
4 Jan 2022 | Sci Total Environ
PFBA, PFBS, and GenX were eliminated faster than PFOS or PFOA in fish.
Analysis of the additional cost of addressing per-and polyfluoroalkyl substance contamination from landfill leachate by reverse osmosis membranes in Thailand
4 Jan 2022 | J. Water Process. Eng.
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
