Several studies estimate that trillions of plastics are floating all
over the oceans (Eriksen et al., 2014), representing one of the most
important threats for marine ecosystems (Cozar et al., 2014). Micro
(o5 mm) and nanoplastics (o100 nm) resulting also from
weathering and fragmentation processes of macro-debris have
been acknowledged as the most dangerous for marine wildlife
since they might be easily ingested causing chemical and physical
effects to marine organisms (Cole et al., 2013). Smaller plastic
pieces can be uptaken and retained by small invertebrates
