Marine fish larvae eat microplastics. Small pieces of plastic, termed ?micro plastic? in the oceans derive mainly from degradation of big plastics such as beach littering, but also from sources of direct emission from example beauty scrubbers and synthetic sand-blasting. These micro plastics are ingested by marine animals ?mistaking them for plankton ? or via prey. When ingested, the particles affect the animals due to their physical properties and their chemical properties (the plastic polymer itself and additives) and persistent organic pollutants (POPs) gathered on their surface. The latter because micro plastics have a large hydrophobic surface, which accumulate POPs to a great extent, on micro plastics than in the surrounding water.
