Food Grown on Fire Stations as a Potential Pathway for Firefighters’ Exposure to Per-and Poly-Fluoroalkyl Substances (PFAS)
Science
15 Aug 2022 | Environ. Int.
Firefighters may be most exposed to PFAS by consuming food grown on fire stations, followed by incidental ingestion and dermal absorption of PFAS in dust.

Exposure to perfluoroalkyl substances and risk of hepatocellular carcinoma in a multiethnic cohort
Science
8 Aug 2022 | JHEP Reports
Exposure to high PFOS levels was associated with an increased risk of non-viral liver cancer, likely via alterations in glucose, amino acid, and bile acid metabolism.

American Chemistry Council Uses Disinformation to Target PFAS Safeguards
News
8 Aug 2022 | The Equation
In its statement about the petition, the ACC claimed to support the development of drinking water standards for the PFAS chemicals PFOA PFOS, PFBS, and GenX. But it speciously charged that EPA was failing to ensure “the scientific integrity of its process.”

Coupling a pathway-oriented approach with tailor-made monitoring as key to well-performing regionalized modelling of PFAS emissions and river concentrations
Science
4 Aug 2022 | Sci Total Environ
A model was developed to assess PFAS emission pathways to rivers, and revealed the dominant PFOS contamination source was municipal wastewater treatment plants.

Outside the Safe Operating Space of a New Planetary Boundary for Per-and Polyfluoroalkyl Substances (PFAS)
Science
2 Aug 2022 | ES&T
PFAS have been detected at unsafe levels in rain globally, leading to the conclusions that the spread of PFOS, PFOA, PFHxS, and PFNA in the atmosphere has exceeded levels of concern for chemical pollution and that PFAS uses and emissions should be rapidly restricted.

Uptake of individual and mixed per- and polyfluoroalkyl substances (PFAS) by soybean and their effects on functional genes related to nitrification, denitrification, and nitrogen fixation
Science
29 Jul 2022 | Sci. Total Environ.
The synergistic effect of a PFAS mixture increased the uptake of individual PFAS in soybeans, which led to changes in genes involved in the nitrogen cycle.
