US officially moves to dismantle drinking water PFAS regulations
News
21 May 2026 | Chemistry World
‘We are fixing that error with standards water systems can actually implement and that will hold up to scrutiny, while addressing PFOA and PFOS, two of the best-studied PFAS with well-documented health impacts,’ EPA Administrator Lee Zeldin stated.

EPA Proposes to Extend Deadlines and Revise Definitions for PFAS Drinking Water Rule
Policy
20 May 2026
The EPA will hold a virtual public hearing on July 7, 2026, to discuss both the proposed deadline extension and the rescission of the four PFAS from the 2024 rule. Read the proposals and submit your comments by July 20, 2026.

PFAS contamination in agricultural systems near an active war zone: Sources, distribution, and crop uptake
Science
20 May 2026 | J. Hazard. Mater.
In the Middle East, PFAS were found in soil and potato plants near an active war zone; farming practices likely explained much of the soil contamination, while contaminated leaves may point to PFAS pollution moving through the air from conflict activity or regional air pollution.

Michigan Health Department releases findings about project on contaminants in firefighters’ blood
News
15 May 2026 | Click On Detroit
Confirmed concentrations for 13 types of PFAS, such as PFOA, PFOS and PFHxS, in the blood of Michigan firefighters.

Per- and polyfluoroalkyl substances in e-waste dust
Science
13 May 2026 | Environ Sci Process Impacts
Dust from Canadian recycling facilities contained many PFAS, especially polyfluoroalkyl phosphate esters, fluorotelomer alcohols, ultrashort PFAS, PFOA, and PFOS, suggesting that workers may face exposure risks and that electronics recycling can release these pollutants into the environment.

Sharp drop in ‘forever chemicals’ in seabird eggs hailed as win for regulation
News
11 May 2026 | The Guardian
The fall coincides with several developments – facing regulatory scrutiny, the chemical giant 3M, which is one of the largest producers of PFAS, began moving away from PFOS, among its most common and toxic compounds.

Recommended toxicity reference values for PFOS and PFHxS in mammals and PFOS in birds
Science
5 May 2026 | Integr Environ Assess Manag
PFOS and PFHxS are associated with population-level reproductive effects at higher exposures, including reduced offspring survival, increased stillbirths, and decreased hatching success, with PFOS showing greater toxicity, while also establishing chronic-dose toxicity reference values to support ecological risk assessments.

‘Forever chemicals’ in baby formula? Scientists unpack FDA results
News
1 May 2026 | State News
The FDA detected five PFAS in the samples it tested, with the most common one — PFOS — found in half of all samples.

A rank order of 26 North American fish species by propensity for PFAS bioaccumulation
Science
30 Apr 2026 | IEAM
PFAS bioaccumulation in fish was found to be species specific, with fish like Brown Trout and Smallmouth Bass consistently showing the highest contamination levels and serving as key indicators of elevated exposure risk.

State study finds PFAS in sewage sludge spread on NC farmland, with no limits in place
News
29 Apr 2026 | WRAL News
PFOS, one of the most studied PFAS compounds, was found in 85% of biosolids samples and in every soil sample collected from fields where sludge had been repeatedly applied.

Multi-media occurrence, bioaccumulation, and exposure assessment of PFAS across a Midwestern US State
Science
27 Apr 2026 | Environ. Res.
A statewide study suggests PFAS, including PFOS and other legacy and newer compounds, are found across air, drinking water, fish, and people in Indiana, where they may build up in food webs and show patterns linked to water system size and community demographics, highlighting multiple exposure pathways and potential environmental justice concerns.

Diet, lifestyle, and sociodemographic influences on serum concentration of PFASs: Insights from human biomonitoring in Switzerland.
Science
17 Apr 2026 | Environ Int
Human biomonitoring in Swiss adults suggests PFAS in the body are largely driven by older, persistent compounds and tend to increase with age and in males, while higher levels are linked to exposures like local freshwater fish consumption and certain product uses, indicating that multiple, compound-specific pathways contribute to overall PFAS burden.

Co-occurrence, bioaccumulation, and dietary risk assessment of per-and polyfluoroalkyl substances and heavy metals in rice
Science
14 Apr 2026 | J Agric Food Chem
Rice grown near a Chinese industrial area was found to accumulate multiple PFAS, including emerging compounds such as HFPO-DA, alongside heavy metals through both soil and irrigation water pathways, with evidence of transfer into edible grains and dietary exposures that may exceed U.S. health-based thresholds.

Volatile per- and polyfluoroalkyl substances (PFAS) and other semi-volatile organic chemicals in indoor air of fire stations: The influence of gear storage conditions
Science
13 Apr 2026 | Environ Sci Process Impacts
Sampling across 11 fire stations identified 14 PFAS and ~120 co-occurring SVOCs in indoor air, with volatile species such as 8:2 FTOH detected at high levels in enclosed gear storage areas, suggesting turnout gear may act as a source of airborne PFAS that could potentially contribute to inhalation exposure and PFOA formation.

Prenatal exposure to per- and polyfluoroalkyl substances (PFAS) and incidence of asthma and wheeze in childhood: A register-based cohort study in Ronneby, Sweden
Science
9 Apr 2026 | PLoS Med
PFAS, including PFOS, PFHxS, and PFOA from AFFF-contaminated drinking water, was associated with increased childhood asthma incidence, while no associations were observed at lower exposure levels, suggesting a possible threshold effect.
