From Lifesaver to Polluter: The Toxic Legacy of Disposable Masks

New research warns that disposable masks used during the Covid-19 pandemic have become a chemical “timebomb” threatening humans, animals, and the environment.

Scientists at Coventry University found that all masks, including high-grade FFP2 and FFP3 types, leach microplastics into water, with some releasing up to six times more than others.

Even more concerning, chemical analysis revealed the presence of bisphenol B, an endocrine disruptor that mimics estrogen and could have long-term health impacts.

During the pandemic, an estimated 129 billion masks were used each month, most ending up in landfills or the environment where they are now degrading.

Researchers warn that protective gear once meant to save lives may instead leave behind toxic risks for generations unless production, disposal, and recycling methods are urgently rethought.
