Breakthrough over potentially harmful chemicals found in most homes

Chemists have identified how to destroy "forever chemicals" in a low-cost way for the first time, new research says.
Scientists have linked exposure to the substances, known as PFAS, at certain levels to serious health risks, including cancer and birth defects.
Their resistance to water, oil and stains make them highly useful. PFAS are used in hundreds of everyday objects from frying pans to make-up.
But it is these properties that make them so difficult to destroy.

PFAS stands for poly- and perfluoroalkyl substances. There are around 4,500 of these fluorine-based compounds and they are found in almost every dwelling on Earth in products including food packaging, non-stick cookware, rain gear, adhesives, paper and paints.
