Metal leaching from antimicrobial cloth face masks intended to slow the spread of COVID-19

Abstract Global health organizations recommend the use of cloth face coverings to slow the spread of COVID-19. Seemingly overnight, companies whose primary business is in no way related to healthcare or personal protective equipment—from mattresses manufacturers to big box stores—transitioned into t...
