PFAS concentrations in the blood of Danish surfers
Science
20 Jan 2025 | Int J Hyg Environ Health
PFAS concentrations in the blood of Danish surfers were measured, revealing no significant relationship between the amount of time spent surfing and higher PFAS levels, but male sex and eating meat from free-ranging animals were found to be potential risk factors for increased exposure.

[Press Release] Attorney General Bonta Co-leads Amicus Brief Defending Nationwide PFAS “Forever Chemicals” Drinking Water Standards
Policy
17 Jan 2025
California Attorney General Rob Bonta today co-led a coalition of 17 states in filing an amicus brief in the U.S. Court of Appeals for the D.C. Circuit defending a U.S. EPA rule establishing the first nationwide drinking water standards for certain toxic PFAS, also known as “forever chemicals,” under the Safe Drinking Water Act.

Unveiling the Truth of Interactions between Microplastics and Per-and Polyfluoroalkyl Substances (PFASs) in Wastewater Treatment Plants: Microplastics as a Carrier of PFASs and Beyond
Science
6 Jan 2025 | Environ. Sci. Technol.
Microplastics in wastewater treatment plants were found to carry PFAS at concentrations ranging from 122 to 166 ng/g, with dominant compounds like PFOS and PFOA showing strong sorption and desorption behaviors, highlighting the dual roles of microplastics as both carriers and sources of PFAS.

Arctic snow shows up to 71 times more PFAS during sunny months
News
19 Dec 2024 | Phys.org
FAS refers collectively to the thousands of man-made chemicals that take a very long time to break down in nature. None of these substances occur naturally—also called forever chemicals, and several are suspected of negatively affecting humans and nature.

Sources and Seasonal Variations of Per- and Polyfluoroalkyl Substances (PFAS) in Surface Snow in the Arctic
Science
26 Nov 2024 | Environ Sci Technol
PFAS in remote Arctic snow formed during long-range atmospheric processes were found to positively correlate with the amount of sunlight, suggesting seasonal influences on their formation and deposition. This study also provided the first evidence for the possible atmospheric formation of PFOS and GenX.
