They are characterized by fluorinated carbon atoms with very strong chemical bonds that persist indefinitely in the environment. Because of this, they have a second name - " eternal chemicals ". used in thousands of consumer products since the 1940s due to their ability to resist heat, water and grease. For example, they are present in: Prevalence of PFAS PFAS accumulate in the environment, so they can also enter the human body through dairy products and meat of animals exposed to chemicals. The compounds are so ubiquitous that scientists have found them in the blood of almost all people tested. Because of these health implications, US state and federal governments are introducing new.
PFAS treatment standards for drinking water and groundwater whatsapp mobile number list from treatment sites. For example, in California, the State Water Control Board issued an executive order in 2022 requiring drinking water suppliers to test for PFAS. If the results exceed the established norms, then the producers must issue a notification about this, eliminate the source of pollution and purify the water. New cleaning method Scientists at the University of California, Riverside have found a method to quickly clean up PFAS . In a patented process, hydrogen is added to polluted water and then irradiated with ultraviolet light. Hydrogen polarizes water molecules, making them more reactive, and light catalyzes chemical reactions that destroy PFAS.
This chemical reaction breaks down the strong bond between fluorine and carbon that makes pollutants so persistent. According to the study, the molecular degradation of PFAS increased from 10% to almost 100% compared to other processing methods. In addition, no other undesirable by-products or impurities were formed in the water. The method is extremely environmentally friendly The cleaning technology is environmentally friendly. The study participant, Associate Professor of the Department of Chemical and Environmental Engineering Haizhou Liu emphasizes : “After the interaction, hydrogen turns into water.
