Scientists in the United States have found a way to breakdown Per- and polyfluorinated alkyl substances (PFAS), also known as forever chemicals, in as little as 45 minutes.
Researchers at the University of California have discovered a simple method of breaking down these chemicals: hydrogen and ultraviolet rays. The method involves taking contaminated water and adding hydrogen. After exposing the solution to ultraviolet light, the toxic substances subsequently break down into smaller cells until they are destroyed or deemed harmless. The success rate using this practice is an incredible 100% (compared to 10% using other methods) and can be attained when treating large quantities at once.
PFAs make up a family of over 4000 chemicals and can be found in a wide array of items including hair and skin products, cosmetics, packaging, fabrics, paper, and electronics. What makes these synthetic chemicals problematic is their inability to be broken down as naturally as more organic substances. They have also been found to contaminate drinking water and can contaminate the body for a period of 8 years before levels decline.
Forever chemicals can have toxic effects on both humans and wildlife, affecting hormonal balance, the reproductive system, and immune system. They can even cause certain cancers such as testicular and kidney cancer.
