What we are breathing through our mouth and nose is actually hazardous waste': Scientists find evidence of toxic chemicals in some face masks. Professor Michael Braungart, director at the Hamburg Environmental Institute, conducted tests on masks which had caused people to break out in rashes.

'What we are breathing through our mouth and nose is actually hazardous waste,' Professor Braungart said.

These used masks were found to contain formaldehyde and other chemicals.

Formaldehyde is the chemical which gives the 'clean' smell when a new pack of masks is opened. He also found aniline, a known carcinogen.

'We found formaldehyde and even aniline and noticed that unknown artificial fragrances were being applied to cover any unpleasant chemical smells from the mask, he said.

'In the case of the blue-coloured surgical masks, we found cobalt – which can be used as a blue dye.

'All in all, we have a chemical cocktail in front of our nose and mouth that has never been tested for either toxicity or any long-term effects on health,' he said. Experts are concerned that the presence of these chemicals in masks which are being worn for prolonged periods of time could cause unintended health issues.

Evidence obtained by Ecotextile News and shared with MailOnline reveals that although face masks should meet specific standards, not all do.

Masks have been mandated in much of the world as they are a highly effective way of preventing transmission of coronavirus particles.

But face coverings designed for use by the general public are not regulated and fail to meet the same standards as medical grade PPE. https://www.dailymail.co.uk/sciencetech/article-9426499/Scientists-evidence-toxic-chemicals-face-masks.html
