Microplastics from face masks: A potential hazard post Covid-19 pandemic
Summary
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.
The tremendous use of plastic products to averse the infection rate during Covid-19 pandemic has developed great pressure on the management and disposal systems of plastic waste. The compulsory use of face masks to curb the infection and prevent transmission of the virus has led to addition of millions of face masks into the terrestrial and marine environment. The current study attempts to assess and quantify the rate of infection in coherence with the annual usage of face masks in various nations across the globe. The ecological footprint of the plastic waste generated from used and discarded face masks along with their potential impacts have also been discussed. The current study has quantified the total annual face masks across thirty-six nations to be more than 1.5 million ton. The total estimated figure for annual plastic waste and microplastics in all these nations was ∼4.2 million tonnes and 9774 thousand tonnes, which emerges as a great threat to the global efforts towards reduction of plastic usage. The emergence of Covid-19 pandemic has modified the living habits with new enterprises being set up for Covid essential products, but the associated hazard of these products has been significantly ignored. Hence this study attempts to present a quantitative baseline database towards interpretation and understanding of the hazards associated with microplastics and increased dependence on plastic products.

Global daily mask use estimation in the pandemic and its post environmental health risks: Analysis based on a validated dynamic mathematical model
Researchers developed a mathematical model to estimate daily disposable mask usage across 214 countries during the COVID-19 pandemic and projected how discarded masks contribute to microplastic pollution. The model estimated billions of masks were used daily at peak periods, releasing massive quantities of microplastic fibers as they degrade. The study provides a tool for policymakers to assess the long-term environmental health risks of pandemic-related plastic waste.
Face masks: a COVID-19 protector or environmental contaminant?
This review examined how the massive global use of disposable face masks during COVID-19 has created a significant source of microplastic pollution, with billions of masks entering the environment and releasing plastic fibers and chemical contaminants.
Global face mask pollution: threats to the environment and wildlife, and potential solutions
Researchers reviewed the global face mask pollution crisis following COVID-19, estimating massive production volumes and finding that most disposal pathways generate secondary microplastic pollution or toxic emissions, and proposing countermeasures including biodegradable mask development and improved waste management policy.
From Protection to Pollution: The Impact of Mask Use on Micro(nano)plastic Release
This bibliographic review found that global mask consumption during COVID-19 reached as high as 2.5 trillion single-use masks per month, with Asia as the largest consumer, and documented how improper mask disposal releases microplastics and nanoplastics into terrestrial and aquatic environments.
The COVID-19 pandemic face mask waste: A blooming threat to the marine environment.
This review examines how single-use face masks — billions of which were discarded during the COVID-19 pandemic — contribute to microplastic and microfiber pollution in marine environments when improperly disposed of. The pandemic created a massive new source of plastic pollution, with masks breaking down into microplastics and releasing chemical contaminants in the ocean.
