Disposable Face Masks Used During Covid Have Left Chemical Timebomb

alternative_right shares a report from The Guardian: It has been estimated that during the height of the coronavirus pandemic 129bn disposable face masks, mostly made from polypropylene and other plastics, were being used every month around the world. With no recycling stream, most ended up either in landfill or littered in streets, parks, beaches, waterways and rural areas, where they have now begun to degrade. Recent research has reported a significant presence of disposable face masks in both terrestrial and aquatic environments.
They left newly bought masks of several different kinds for 24 hours in flasks containing 150ml of purified water, then filtered the liquid through a membrane to see what came out. Every mask examined... leached microplastics, but it was the FFP2 and FFP3 masks -- marketed as the gold-standard protection against the transmission of the virus -- that leached the most, releasing four to six times as many. And they made an even more worrying discovery.

Subsequent chemical analysis of the leachate found medical masks also released bisphenol B, an endocrine-disrupting chemical that acts like oestrogen when absorbed into the bodies of humans and animals. Taking into account the total amount of single-use face masks produced during the height of the pandemic, the researchers estimated they led to the release of 128-214kg of bisphenol B into the environment. The findings have been published in the journal Environmental Pollution.
