Microplastics from urban rivers and streams are a major contributor to fatal ocean pollution when they flood, a study has found.
Researchers from the University of Manchester found microplastics, tiny pieces of plastic debris such as microbeads and microfibres, are shifted into the seas particularly after flooding.
They are toxic to ecosystems including marine life.
A river in Greater Manchester was identified as having the highest levels of contamination by the particles anywhere in the world. MORE
