Analysis of the additional cost of addressing per-and polyfluoroalkyl substance contamination from landfill leachate by reverse osmosis membranes in Thailand
Science
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
Science
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.

PFAS destruction technologies are starting to emerge
News
29 Dec 2021 | C&EN
Communities across the US are desperate to rid their environments of toxic per- and polyfluoroalkyl substances (PFAS), especially when these chemicals are in their drinking water.

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
Science
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.

PFASs pollution in Galveston Bay surface waters and biota (shellfish and fish) following AFFFs use during the ITC fire at Deer Park (March 17th-20th 2019), Houston, TX
Science
30 Nov 2021 | Sci Total Environ
High PFAS levels were measured in water following AFFF usage on a nearby petrochemical fire and a risk assessment suggested a fish consumption advisory to protect against human exposure.

Maine found ‘forever chemicals’ in deer, but has no idea how widespread the problem is
News
24 Nov 2021 | Bangor Daily News
The discovery of “forever chemicals” in deer in central Maine and the subsequent guidance to not eat the meat raises serious questions about whether it is safe to consume venison killed in areas of the state where high levels of the chemicals have been detected or are suspected to exist.

Uptake of perfluoroalkyl substances, pharmaceuticals, and parabens by oyster mushrooms (Pleurotus ostreatus) and exposure risk in human consumption
Science
24 Nov 2021 | Chemosphere
Uptake of PFAS by oyster mushrooms was negatively correlated with perfluorocarbon chain length, and mushrooms grown in soil contaminated by PFAS may pose a risk if consumed.

What difference can drop-in substitution actually make? A life cycle assessment of alternative water repellent chemicals
Science
22 Nov 2021 | J. Clean. Prod.
A life cycle assessment found non-fluorinated durable water repellents for outdoor garments were environmentally preferable to fluorinated variants leading to the recommendation to phase out PFAS.
