Microplastics and other emerging contaminants in the environment after COVID-19 pandemic: The need of global reconnaissance studies

Evidence of the increase of emerging contaminants in the environment due to the COVID-19 pandemic, such as personal protective equipment (PPE), disinfectants, pharmaceuticals, etc., has enlarged. Here we explain the variety of pathways of these emerging contaminants to enter the environment, including wastewater treatment plants, improper disposal of PPE, and runoff from surfaces treated with disinfectants. We also discuss the current state-of-art of the toxicological impli-cations of these emerging contaminants. Initial research sug-gests that they may have harmful effects on aquatic organisms and human health. Future directions are suggested as further research is needed to fully understand the impacts of these contaminants on the environment and humans, as well as to develop effective approaches to mitigate their potential nega-tive effects.

Automated summary

Evidence shows an increase in emerging contaminants, such as PPE, disinfectants, and pharmaceuticals, in the environment due to the COVID-19 pandemic. This article discusses the various pathways through which these contaminants enter the environment, including wastewater treatment plants, improper disposal of PPE, and surface runoff from disinfectant-treated areas. The potential harmful effects of these emerging contaminants on aquatic organisms and human health are also addressed, highlighting the need for further research to understand their impacts and develop effective mitigation strategies.
