Degradation of plastics associated with the COVID-19 pandemic
AI summary Read the abstract
This review examines how personal protective equipment from the COVID-19 pandemic degrades in the environment and becomes a source of microplastic pollution. Researchers found that face masks, primarily made of polypropylene, break down into microfibers relatively quickly when exposed to weathering. The study highlights that pandemic-related plastic waste represents a new and significant category of environmental microplastic contamination.
The ongoing COVID-19 pandemic has resulted in an unprecedented form of plastic pollution: personal protective equipment (PPE). Numerous studies have reported the occurrence of PPE in the marine environment. However, their degradation in the environment and consequences are poorly understood. Studies have reported that face masks, the most abundant type of PPE, are significant sources of microplastics due to their fibrous microstructure. The fibrous material (mostly consisting of polypropylene) exhibits physical changes in the environment, leading to its fracture and detachment of microfibers. Most studies have evaluated PPE degradation under controlled laboratory conditions. However, in situ degradation experiments, including the colonization of PPE, are largely lacking. Although ecotoxicological studies are largely lacking, the first attempts to understand the impact of MPs released from face masks showed various types of impacts, such as fertility and reproduction deficiencies in both aquatic and terrestrial organisms.

Microplastics/nanoplastics released from facemasks as contaminants of emerging concern
AI summary Read the abstract
This review examines how disposable facemasks, made primarily from polypropylene and polyethylene, release microplastics and nanoplastics into the environment. Chemical, physical, and biological processes break down discarded masks into tiny plastic particles that persist in ecosystems. Given the billions of masks used during COVID-19, this represents a significant and growing source of microplastic pollution.
