Scientists Develop Light-Based Method to Break Down PFAS 'Forever Chemicals'

A new photocatalytic system shows promise in degrading persistent PFAS compounds, but scaling up remains a challenge.

PFAS, or 'forever chemicals,' are synthetic compounds used in products like nonstick cookware and firefighting foam, known for their environmental persistence and health risks.
Researchers have developed a photocatalytic system using blue LED light to break down the strong carbon-fluorine bonds in PFAS molecules.
The method transforms PFAS into harmless byproducts, such as hydrocarbons and fluoride ions, which can be safely reabsorbed into the environment.
Current challenges include scaling the system for widespread use and improving the long-term stability of the organic photocatalysts used in the process.
Studies show PFAS contamination disproportionately affects vulnerable communities near industrial sites, highlighting environmental justice concerns.
