Washington. Along with lifestyle, the amount of pollutants in the environment is also increasing. These hazardous substances are entering the air, soil, groundwater, lakes and rivers as a result of industrial processes, thereby polluting the environment. You will be surprised to know that the Forever chemicals used in items of daily use like non-stick pans have been the cause of serious diseases for a long time.
The US and China have found a better way to destroy the polluting compound PFAS, according to research published in a science journal. Which has been a serious threat to the environment, animals and humans for a long time. That’s why, ‘I’m interested in science so I can make a positive impact on the world,’ senior author William Dichtel of Northwestern University said during a press conference following the discovery.
What is PFAS?
The polyfluoroalkyl substance PFAS was first developed in the 1940s. Now it is found in a wide variety of products. These include non-stick pans, waterproof fabric, and fire retardant foam. The carbon-fluoride bond is considered the strongest bond in chemistry. For this reason, eliminating PFAS is seen as a challenging process.
How will it be destroyed?
The current methods of destroying PFAS are not easy. Because it requires incineration at very high temperatures and they are irradiated with ultrasonic waves. While it also pollutes the environment with smoke during burning. In the second part of the study, the team followed its weak end to destroy the atoms. Due to which this compound can be destroyed even in low temperature.

What are the dangers of PFAS?
A recent review by the Centers for Disease Control and Prevention (CDC) has outlined several health effects associated with PFAS exposure. These include cancer, liver damage, decreased fertility, and an increased risk of asthma and thyroid disease.
