Microplastics from face masks: A potential hazard post Covid-19 pandemic

Researchers quantified the annual face mask usage and associated plastic waste across 36 countries during the COVID-19 pandemic, estimating total annual mask usage exceeding 1.5 million tonnes and associated plastic waste of approximately 4.2 million tonnes. The study highlights that global COVID-19 responses substantially increased environmental microplastic burdens from single-use face mask disposal.

A review of disposable facemasks during the COVID-19 pandemic: A focus on microplastics release

This review examines the environmental threats posed by disposable face masks used during the COVID-19 pandemic, with a focus on microplastic release. Researchers found that discarded masks undergo physical and chemical degradation in the environment, generating microplastics that contaminate both aquatic and terrestrial ecosystems. The study provides an overview of current knowledge on microplastic extraction methods and proposes strategies for controlling mask-related plastic pollution through source reduction and improved waste management.

Kinetic characteristics of microplastic release from commonly used masks in aquatic environment

Researchers tested four mask types (normal, fashion, N95, and disposable surgical) by exposing them to simulated natural water environments over 12 months at 3-month intervals to characterize the kinetics of microplastic release. They found time-dependent release patterns that varied by mask construction, documenting structural degradation and quantifying microplastic fiber shedding as a function of duration, with implications for environmental risk assessment of pandemic-related mask pollution.
