Summary
Tiny particles carry pollutants and microbes and are ingested at every trophic level.
In depth
Primary microplastics (microbeads) and secondary (from fragmentation). Zooplankton and fish ingest them; effects include reduced feeding, inflammation and transfer of additives. Nanoplastics can cross membranes. Biofilms colonise them (plastisphere).
Sampling uses nets and filtration; identification uses spectroscopy. Effects on organisms depend on particle type, size and chemicals. Evidence for human health impacts is emerging.
Key idea: microplastics are now found everywhere, from Arctic ice to deep trenches.
