Disposable COVID Masks Release Harmful Microplastics, Research Finds

Research led by Coventry University has revealed that disposable face masks used extensively during the COVID-19 pandemic are a significant source of environmental pollution, releasing microplastics and harmful chemical additives even when unused. The study found that filtering facepiece masks release three to four times more microplastics than standard surgical masks, with particles primarily made of polypropylene and other resilient plastics that persist in ecosystems. These microplastics and chemicals, including endocrine disruptors such as Bisphenol B, pose risks to human health, aquatic life, and biodiversity as they accumulate in waterways and food chains. The findings highlight the lack of effective recycling or disposal plans for the estimated 129 billion masks used monthly during the pandemic, leading to widespread contamination of land and water environments. Researchers emphasize the urgent need to rethink mask production, use, and disposal to mitigate this emerging chemical timebomb. This issue underscores the hidden environmental costs of reliance on single-use protective gear during health crises.
