Pollution: 'Forever chemicals' in rainwater exceed safe levels
News
2 Aug 2022 | BBC
New research shows that rainwater in most locations on Earth contains levels of chemicals that "greatly exceed" safety levels.

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.

The Association of Per-and Polyfluoroalkyl Substances Serum Levels and Allostatic Load by Country of Birth and the Length of Time in the United States
Science
1 Aug 2022 | Int. J. Environ. Res. Public Health
Foreign-born individuals tend to have higher levels of serum PFAS the longer they stay in the United States.

Leveraging Systematic Reviews to Explore Disease Burden and Costs of Per and Polyfluoroalkyl Substance
Science
1 Aug 2022 | Exposure and Health
This study identified at least $5.5 billion in annual disease burden and social costs due to long-chain PFAS exposure, demonstrating that regulatory actions to limit PFAS use and remediate contaminated water may produce substantial economic benefits.

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.

Mitigating PFAS, Plastics-Related Litigation Costs With Insurance
News
29 Jul 2022 | Bloomberg Law
Litigation trends involving plastics as well as PFAS are significant enough that companies with potential exposure would be well served to consider how insurance coverage may fit into their larger risk mitigation plans.

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.

South Adams County water district is buying Denver’s water to dilute “forever chemicals”
News
27 Jul 2022 | The Colorado Sun
The district, serving Commerce City and surrounding areas, will need a $130 million plant to meet the EPA’s radically lower guidelines for what’s healthy in drinking water.

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.

Are cosmetics a significant source of PFAS in Europe? product inventories, chemical characterization and emission estimates
Science
21 Jul 2022 | Environ Sci Process Impacts
Annual European-wide cosmetic-related total fluorine and extractable organic fluorine emissions to wastewater and solid waste ranged from 17-38,000 kg F per year and 37-5100 kg F per year, respectively, representing a high emission source that is still lower than emissions from washing PFAS-coated textiles.

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.

Occurrence and Fate of Ultrashort-Chain and Other Per-and Polyfluoroalkyl Substances (PFAS) in Wastewater Treatment Plants
Science
19 Jul 2022 | ACS ES&T Water
The transformation of precursors into shorter chain PFAAs by biological treatment and the partitioning of longer chain PFAS into sludge streams are key factors determining the fate of PFAS in wastewater treatment plants.
