"Pollution: 'Forever Chemicals' In Rainwater Exceed Safe Levels"

"New research shows that rainwater in most locations on Earth contains levels of chemicals that "greatly exceed" safety levels.

These synthetic substances called PFAS are used in non-stick pans, fire-fighting foam and water-repellent clothes.

Dubbed 'forever chemicals', they persist for years in the environment.

Such is their prevalence now that scientists say there is no safe space on Earth to avoid them."
