The 'forever chemicals' lurking in our water and clothes

PFAS can also be found in our blood and our brains.

Do you know there could be chemicals in your clothes, food packaging and even your make-up which can take hundreds or even thousands of years to break down?

They鈥檙e called PFAS - or 鈥渇orever chemicals鈥 - and they are everywhere. They're in our drinking water, at harmful levels in some areas, and they鈥檙e inside our bodies, our brains and our blood. They鈥檝e been found on the top of Mount Everest, too.

麻豆社 climate and science reporter Esme Stallard explains what these chemicals are and how they get into our bodies. Stephanie Metzger from the Royal Society of Chemistry in the UK tells us the effect they can have on our health. And podcast host Robin Laird tells us what she does to try to avoid PFAS.

France has just brought in a ban on cosmetics and clothing that contain these chemicals - they can鈥檛 be produced, imported or sold there now. We hear about the steps some countries are taking to try to limit their use. Gittemarie Johansen, a Danish environmental and sustainability advocate, gives us her view on what governments and manufacturers should do.
