Is your takeaway pizza box leaking toxic chemicals into your dinner? The UK government wants to find out, as it launches an official investigation this week into PFAS - aka ‘forever chemicals’. Invented in the 1940s, they were designed to make products grease-proof, from non-stick pans to waterproof rain coats. But there are major health concerns associated with PFAS, as they spend years in the human body - and natural environment - without breaking down. So what's the government's plan and does it go far enough? #health #PFAS #foreverchemicals #environment #C4News
