“…Since the declaration of the Covid-19 disease as a pandemic by the World Health Organization ( WHO, 2020 ), disposable personal protective equipment (PPE) has been adopted as an essential measure to prevent the spread of the infection. Several authors ( Abedin et al, 2022a ; Abedin et al, 2022b ; Akhbarizadeh et al, 2021b ; De-la-Torre and Aragaw, 2021 ; De-la-Torre et al, 2022b ; Rakib et al, 2021 ) have shown how the indiscriminate disposal of PPE wastes and their accumulation in beaches, coastlines, rivers, and littering cities can be a significant source of microplastics, although the magnitude of this contamination is still unknown. Face masks, the most abundant type of PPE, if exposed to environmental conditions, may be compromised in their fibrous structure, leading to rougher surfaces, cracks, ruptures, and releasing of microfibers.…”
