How Colorado is preventing PFAS contamination from the oil and gas industry
Policy
4 Aug 2022
In June, Colorado became the first state to ban the use of PFAS during oil and gas extraction — and now, in light of recent research finding the potential for widespread contamination, some are calling for a similar ban in Pennsylvania.

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.

The PFAS-Tox Database: A systematic evidence map of health studies on 29 per- and polyfluoroalkyl substances
Science
1 Aug 2022 | Environ. Int.
In this summary of the PFAS-Tox Database we provide examples of data gaps and clusters revealed by the database, with the goal of helping direct future research efforts, facilitate systematic reviews (e.g. on immune effects, mixtures of PFAS, or effects of short chain PFAS), inform regulatory risk assessments, and improve opportunities for cross-disciplinary coordination.

Rhode Island PFAS Regulations Become Law
Policy
1 Aug 2022
On June 27, 2022, Rhode Island passed two new laws into effect that regulate six types of PFAS in food packaging, drinking water, ground water, surface waters, and landfills.

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.

Per-and polyfluoroalkyl substances in the atmosphere of waste management infrastructures: Uncovering secondary fluorotelomer alcohols, particle size distribution, and human inhalation exposure
Science
29 Jul 2022 | Environ. Int.
PFAS were prevalent in the air and in particulate matter near landfills and wastewater treatment plants, and modeling demonstrated that fine and ultrafine particles may carry PFAS into the lung alveoli.

Doctors should test levels of PFAS in people at high risk, report says
Policy
28 Jul 2022
On Thursday, the prestigious National Academies of Sciences, Engineering, and Medicine strode into the fray with a 300-plus-page report providing detailed advice for clinicians on how to test, diagnose and treat the millions of Americans who may have been exposed to PFAS.

Per- and polyfluoroalkyl substances (PFASs) in consumable species and food products
Science
28 Jul 2022 | J Food Sci Technol
This review found that legacy PFAS remain in high abundance and that proximity to factories and fluorochemical industries results in potentially hazardous levels of PFAS contamination in all types of food products.

Increasing Accumulation of Perfluorocarboxylate Contaminants Revealed in an Antarctic Firn Core (1958–2017)
Science
26 Jul 2022 | ES&T
PFCA and PFBA accumulation in snow increased, and although chemical fluxes of PFOA and PFNA peaked in 2009–2013, there is little evidence of a decline in PFAAs despite supposed recent global curtailments in their production.

Extensive wildlife testing for PFAS could result in more ‘do not eat’ advisories
News
25 Jul 2022 | Bangor Daily News
Nearly eight months after the Maine Department of Inland Fisheries and Wildlife issued a ‘do not eat’ advisory for deer harvested in Fairfield because of the presence of PFAS, the department will return to the area.

Adsorption of per-and polyfluoroalkyl substances (PFAS) to containers
Science
21 Jul 2022 | J. Hazard. Mater.
Containers used to hold PFAS mixtures adsorbed the chemicals at different rates based on PFAS chemistry, container hydrophobicity, temperature, and container manufacturer, with the general trend of PFAS adsorption as polypropylene > HDPE > PET > glass > polystyrene.
