The diffusion of Coronavirus disease (COVID-19) impacted the whole world, changing the life habits of billions of people These changes caused an abundant increase in personal protective equipment (PPE, e g , masks and gloves) use by the general population, which can become a concerning issue of plastic pollution This study aims to evaluate the negative effects of the abundant PPE use following the COVID-19 diffusion using the test site of the Lombardy region, an area highly affected by the pandemic Population data were retrieved from national databases, and the COVID-19 national guidelines were considered to estimate the total use of PPEs during 2020 Then, the quantity of waste derived from their use was evaluated based on the weight of PPEs As well, possible scenarios for 2021 were proposed based on 2020 estimations The results suggested different negative effects of the diffusion of PPEs both on waste management and on the environment: The abundant increase in PPEs-derived waste caused an increase in terms of costs for management, and the potential direct spreading in the environment of these materials (especially masks) poses a serious threat for an increase in microplastics in water bodies Following this evaluation, a careful choice regarding COVID-19 measures of containment should be performed especially by the general population, avoiding contagion diffusion and reducing the possible environmental impact derived from disposable PPE use
