    Tyres specifically break down on hard surfaces that typically drain directly to a nearby waterway. Used tyres were/are popular for boat fenders and seawalls and the like. That and literally just dumping them. I’m not surprised.

      City storm drainage is already treated for a population over 100k (in the us). But never for these microplastics. Seems like that would be a good place to start.
