Scientists have found evidence that some face masks which are on sale and being used by members of the general public are laced with toxic chemicals.
Preliminary tests have revealed traces of a variety of compounds which are heavily restricted for both health and environmental reasons.
This includes formaldehyde, a chemical known to cause watery eyes; a burning sensations in the eyes, nose, and throat; coughing; wheezing; and nausea.
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.
