New research will track how tiny plastic particles from tyres, polyester clothing and fishing gear enter the oceans and affect marine life.
The Government has pledged £200,000 for scientists at the University of Plymouth to research how the particles known as ‘microplastics’ end up in the seas.
The project comes after the introduction of a ban on miniature plastic beads or 'microbeads' in care products, where the plastics can be washed down the drain.
Small plastic particles, including from car tyre friction on roads or fibres from synthetic clothes released during washing, have been found in places as remote as the Arctic sea ice.
The project is being led by Professor Richard Thompson
The 11-month project will build on research already underway, with scientists estimating that tyres contribute 270,000 tonnes of plastics per year while a single wash load of acrylic clothing could release more than 700,000 microfibres into the ocean.
