Post-pandemic micro/nanoplastic pollution: Toward a sustainable management
AI summary Read the abstract
Researchers reviewed how the COVID-19 pandemic contributed to micro- and nanoplastic pollution through the massive use of disposable personal protective equipment like masks and gloves. The study found that weathering of these items releases microplastics into the environment and may even serve as carriers for pathogens. The review calls for more sustainable waste management approaches in preparing for future health crises.
The global health crisis caused by the COVID-19 pandemic has resulted in massive plastic pollution from the use of personal protection equipment (PPE), with polypropylene (PP) being a major component. Owing to the weathering of exposed PPEs, such contamination causes microplastic (MP) and nanoplastic (NP) pollution and is extremely likely to act as a vector for the transportation of COVID-19 from one area to another. Thus, a post-pandemic scenario can forecast with certainty that a significant amount of plastic garbage combined with MP/NP formation has an adverse effect on the ecosystem. Therefore, updating traditional waste management practices, such as landfilling and incineration, is essential for making plastic waste management sustainable to avert this looming catastrophe. This study investigates the post-pandemic scenario of MP/NP pollution and provides an outlook on an integrated approach to the recycling of PP-based plastic wastes. The recovery of crude oil, solid char, hydrocarbon gases, and construction materials by approximately 75, 33, 55, and 2 %, respectively, could be achieved in an environmentally friendly and cost-effective manner. Furthermore, the development of biodegradable and self-sanitizing smart PPEs has been identified as a promising alternative for drastically reducing plastic pollution.

Personal protective equipment (PPE) disposal during COVID-19: An emerging source of microplastic and microfiber pollution in the environment
AI summary Read the abstract
This review examines how discarded personal protective equipment from the COVID-19 pandemic has become a new source of microplastic and microfiber pollution. Researchers found that single-use masks, gloves, and other PPE break down into tiny plastic particles that contaminate water, soil, and air. The study highlights the environmental trade-off of pandemic safety measures and calls for better waste management strategies for healthcare materials.
Personal protective equipment and micro-nano plastics: A review of an unavoidable interrelation for a global well-being hazard
AI summary Read the abstract
This review examines how personal protective equipment like masks and gloves, widely used during the COVID-19 pandemic, breaks down into micro- and nanoplastics when improperly disposed of. These tiny plastic fragments enter the environment and have been shown to be harmful to living organisms based on their size, shape, and chemical makeup. The study highlights a growing concern that pandemic-era protective gear is contributing to plastic pollution in soil, water, and air.
Review on personal protective equipment: Emerging concerns in micro(nano)plastic pollution and strategies for addressing environmental challenges
AI summary Read the abstract
This review examines how the massive increase in disposable masks, gloves, and other protective equipment during COVID-19 has become a major new source of microplastic pollution. An estimated 1.6 million tons of plastic waste per day was generated from discarded protective equipment, and as this gear breaks down, it releases micro- and nanoplastic particles into soil and water. These particles can accumulate in seafood and other organisms, creating another pathway for human microplastic exposure.
