Major study reveals substantial quantities of tyre particles contaminating our rivers and ocean - University of Plymouth

Research led by the University reveals vital new information that will improve our scientific understanding of how tiny particles enter the ocean

A major government-funded research study published today suggests particles released from vehicle tyres could be a significant and previously largely unrecorded source of microplastics in the marine environment.

The study is one of the first worldwide to identify tyre particles as a major and additional source of microplastics. Scientists have previously discovered microplastics, originating from microbeads in cosmetics and the degradation of larger items such as carrier bags and plastic bottles, in marine environments globally – from the deep seas to the Arctic.

Following the Government’s ban on rinse off microbeads, which is one of the toughest in the world, the Defra-funded study led by the University of Plymouth now reveals vital new information that will improve our scientific understanding of how tiny particles from tyres, synthetic fibres from clothing and maritime gear also enter the ocean.

This project will be used to guide future research already underway on marine plastic pollution and the impact of human activities on the marine environment, as the Government continues in its fight against the scourge of plastics. This includes the 5p plastic bag charge – which has led to 15 billion fewer bags distributed – and plans to end the sale of plastic straws and stirrers and plastic-stemmed cotton buds later this year.

The study shows the tyre particles can be transported directly to the ocean through the atmosphere, or carried by rainwater into rivers and sewers, where they can pass through the water treatment process. Researchers estimate this could place around 100million m² of the UK’s river network – and more than 50million m² of estuarine and coastal waters – at risk of contamination by tyre particles.
