Discarded COVID-19 Masks Pose Major Environmental Threat
A new study has found that billions of disposable face masks (DFMs) used during the COVID-19 pandemic now pose a significant environmental risk. Improperly discarded masks, particularly the N95 variety, are contributing to widespread microplastic pollution and releasing toxic chemicals into the environment.
The Scale of the Problem
The pandemic saw a dramatic surge in the use of disposable masks, with a study in the journal Environment Pollution estimating that their use increased by nearly 9,000% between March and October 2020. Globally, an additional 129 billion DFMs were used monthly. These masks, made from non-recyclable polymers like polypropylene, were often improperly discarded on streets, in parks, and in waterways, where they now pose a persistent threat.
