Bioremediation of perfluorochemicals: current state and the way forward
Science
7 Feb 2022 | Bioprocess Biosyst Eng
This review examines the efficiencies of the different bacterial, plant, and fungal species in PFAS bioremediation under different conditions, their limitations, and their improvement.

Release of perfluoroalkyl substances from AFFF-impacted concrete in a Firefighting Training Ground (FTG) under repeated rainfall simulations
Science
7 Feb 2022 | J. Hazard. Mater.
High concentrations of 5 PFAS were measured in concrete cores removed from firefighting training grounds, and simulated rainfall released approximately 1% of the total PFAS mass in the concrete surface layer, leading researchers to believe that concrete can be a secondary source of PFAS contamination.

Industrial byproducts for the soil stabilization of trace elements and per-and polyfluorinated alkyl substances (PFASs)
Science
25 Jan 2022 | Sci Total Environ
Industrial byproducts can provide sustainable and cost-effective materials for soil remediation of PFAS, but the sorbent must be tailored to the type of soil and type of contamination.

US EPA sued over gaps in PFAS release reporting
News
21 Jan 2022 | C&EN
Advocacy groups are asking a federal court to force the US Environmental Protection Agency to plug what they call loopholes in two rules on reporting releases of dozens of toxic, highly persistent chemicals.

Bioaccumulation and impact of maternal PFAS offloading on egg biochemistry from wild-caught freshwater turtles (Emydura macquarii macquarii)
Science
17 Jan 2022 | Sci Total Environ
PFAS from the mothers were found to bioaccumulate in egg yolks which contained up to 97% of bioaccumulated PFAS, and impacted eggs had changes in metabolite, lipid, and protein levels.

A worldwide evaluation of trophic magnification of per- and polyfluoroalkyl substances in aquatic ecosystems
Science
17 Jan 2022 | Integr Environ Assess Manag
This review discusses the variability of environmental characteristics driving PFAS biomagnification in natural ecosystems and highlights the different approaches used by various studies, which can make comparisons among studies challenging.

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.

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.
