"Microplastics are usually defined as plastic items which measure less than 5 mm\nin their longest dimension, this definition includes also nanoplastics which are\nparticles less than 100 nanometres (nm) in their longest dimension. Plastic items may\nbe manufactured within this size range (primary micro- and nanoplastics) or result\nfrom the degradation and fragmentation of larger plastic items (secondary micro- and\nnanoplastics)."@en .
