Prevalence of Covid-19 personal protective equipment in aquatic systems and impact on associated fauna

The use and undesignated disposal of COVID-19 related personal protective equipments (PPEs) has resulted in a spike in the global mismanagement of plastic waste. Moreover, the SARS-CoV-2 pandemic has not only affected the socio-economic state of the world but is contributing significantly to the already existing aquatic pollution dilemma. Consequently, PPE litter is an emerging pollutant in aquatic ecosystems that warrants significant attention. This review endeavoured to present a synopsis of the global mismanagement of PPE waste and highlight the devastating ramifications of the ensuing environment. The paper reveals that PPE litter is indeed negatively impacting environmental systems on varying levels around the globe. Furthermore, peak plastic loads are transported by Asian rivers and are deposited into the Pacific and Indian Oceans. Beaches and seabed are the major sinks of COVID-19 PPE litter making benthic organisms to be the most vulnerable. More studies need to be undertaken to monitor aquatic resources to get a detailed overview of COVID-19 PPE litter in the environment.
