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

Area of Science:

• Environmental Science
• Public Health
• Materials Science

Background:

• The COVID-19 pandemic necessitated increased use of plastic products, particularly face masks, to control infection rates.
• This surge in plastic consumption has overwhelmed waste management systems and introduced substantial plastic waste into terrestrial and marine environments.
• The ecological impact of disposable face masks and other COVID-19 essential products remains a significant concern.

Purpose of the Study:

• To quantify the annual usage of face masks globally in relation to infection rates.
• To assess the ecological footprint and potential impacts of plastic waste generated from discarded face masks.
• To establish a quantitative baseline for understanding the hazards of microplastics and increased plastic dependence.

Main Methods:

• Analysis of annual face mask usage data across thirty-six nations.
• Quantification of total annual plastic waste and microplastic generation.
• Evaluation of the ecological footprint associated with pandemic-related plastic waste.

Main Results:

• Over 1.5 million tons of face masks were used annually across the studied nations.
• The total estimated annual plastic waste reached approximately 4.2 million tonnes, with microplastics accounting for 9774 thousand tonnes.
• This substantial increase in plastic waste threatens global plastic reduction initiatives.

Conclusions:

• The widespread use of face masks during the pandemic has generated a massive amount of plastic waste, contributing significantly to microplastic pollution.
• The environmental hazards associated with these single-use plastic products have been largely overlooked.
• There is an urgent need to address the increased dependence on plastic products and mitigate the associated microplastic risks.
