PFAS

Most research on “forever chemicals” focuses on how best to remove them from the environment. But solutions to tricky problems often emerge from the most unexpected of places—as demonstrated by a new study that instead redirects the pollutants into becoming tools for extracting precious lithium. In a recent Nature Water study, a team led by Rice University researchers describes a novel way to use spent perfluoroalkyl and polyfluoroalkyl substances, or PFAS, to recover lithium from high-salinity brine pools. The team tapped into the fluorine content inside PFAS leftovers, using it to attract lithium from briny water. Remarkably, the team was able to collect lithium fluoride at 99% purity and confirmed that the sample was pure enough to boost the stability and performance of lithium-ion batteries.

The Environmental Protection Agency is moving forward with approvals for pesticides containing “forever chemicals” as an active ingredient, dismissing concerns about health and environmental impacts raised by some scientists and activists. This month, the agency approved two new pesticides that meet the internationally recognized definition for per- and polyfluoroalkyl substances, also known as PFAS or fluorinated substances, and has announced plans for four additional approvals.

Forever chemicals have polluted the water supply of 60,000 people, threatening human health, wildlife and the wider ecosystem. But activists say this is just the tip of the Pfas iceberg

When a small Swedish town discovered their drinking water contained extremely high levels of Pfas, they had no idea what it would mean for their health and their children’s future

Millions of Americans rely on drinking water systems that have detected these forever chemicals at levels above the now-abandoned limits.

A study led by the Joe C. Wen School of Population & Public Health at the University of California, Irvine has revealed possible links between exposure to per- and polyfluoroalkyl substances in drinking water and an increased risk of certain childhood cancers.

While NGOs and Members of the European Parliament are calling for a ban on so-called "forever chemicals" in pesticides, only a few kilometres from Brussels, in Flanders, contamination is in full swing, even affecting organic farmers. PFAS (per- and polyfluoroalkyl substances) are chemicals used mainly for their water-repellent properties. Recent studies suggest that pesticide products may contain PFAS and that some active ingredients may meet the definition of a PFAS. This group of chemicals is a known threat to human health. Once in the environment, they are extremely persistent, earning them the nickname "forever chemicals".

Plastic pollution and forever chemicals are so widespread they’re even in the rain, putting public health and natural ecosystems at risk.

The multibillion-dollar chemicals company 3M told customers its firefighting foams were harmless and biodegradable when it knew they contained toxic substances so persistent they are now known as “forever chemicals” and banned in many countries including the UK, newly uncovered documents show.

Hastened reviews of compounds as industry ramps up could increase pollution from likely toxic chemicals. The Environmental Protection Agency is quietly fast tracking approval of new PFAS “forever chemicals” for use by the semiconductor industry at the same time the agency is publicly touting increased scrutiny of new PFAS and other chemicals.

A chemical that takes thousands of years to break down is found in England's freshwater fish at 1,000 times above safe levels – and could end up on our dinner tables

Per- and polyfluoroalkyl substances (PFAS) have been at the center of numerous toxicological and environmental concerns and regulatory scan- dals for two decades. Previous research has shown a long history of active obfuscation, misdirection (‘science bending’) and regulatory manipulation by the largest halogenation businesses, related to the depletion of the ozone layer and the toxicity of some fluorinated surfactants (PFOS and PFOA). We screened publications for potential evidence of other strategies of deception and obfuscated information regarding PFAS and fluoropolymers. A directed effort was identified to influence the scientific understanding of the environmental source and effects of ultrashort PFAS, especially trifluoroacetic acid (TFA). Critical issues in the current analytical approach to PFAS monitoring were identified, as well as evidence of a silently abandoned “total organofluoride” technique. The non-specific character of the production, incineration and degradation processes is discussed, inc

Chemicals yield profit of about $4bn a year for the world’s biggest PFAS manufacturers, Sweden-based NGO found

Those with higher levels of PFAS in their blood had 40% lower chance of conceiving within a year of trying

Research finds waste flushed down toilets and sent to sewage plants probably responsible for significant source of water pollution

More than 17 000 sites all over Europe are contaminated by the “forever chemicals” PFAS, an exclusive, months-long investigation from 18 European newsrooms shows. The investigation “The Forever Pollution Project” reveals an additional 21 000 presumptive contamination sites due to current or past industrial activity. The contamination revealed by this project spreads all over Europe.

Major mapping project reveals PFAS have been found at high levels at thousands of sites across Europe. EURACTIV's media partner, The Guardian, reports. Pollutants known as “forever chemicals”, which don’t break down in the environment, build up in the body and may be toxic, have been found at high levels at thousands of sites across the UK and Europe, a major mapping project has revealed.

Poly- and perfluoroalkyl substances (PFAS) and global climate change have attracted worldwide attention. PFAS have been found all across the planet, from the polar regions to the global ocean. Global oceans have emerged as a substantial sink for the carbon in the environment due to their remarkable capacity to absorb atmospheric carbon. Oceans absorb around 24% of the world’s CO2 emissions. Thus, the ocean plays a prominent role in the earth’s carbon cycle. However, the widespread application of PFAS in a wide range of products and the inefficient management of PFAS-containing wastes made them ubiquitous pollutants, which are increasingly getting as a pollutant of emerging concern. Marine PFAS pollutants can produce harmful effects on gas exchange and the ocean’s carbon cycle. Thus, it leads to an increase in greenhouse gas emissions, which eventually adversely affects global warming and climate change. Consequently, threats of marine PFAS to oceans carbon sequestration are discussed in this paper. Marine PFA

There are likely more than 57,000 locations, with sites in all 50 states and the District of Columbia, that are contaminated with the toxic forever chemicals known as per- and poly-fluoroalkyl substances (PFAS).
