Road stormwater is often contaminated with a variety of substances, such as metals, sediments and organic pollutants. In recent years, road runoff has also been identified as a significant source of microplastics. Above all, tire and bitumen particles occur. There is very little data and experience on cleaning microplastics from stormwater. This study has evaluated the presence and purification of various microplastic polymers in runoff from E4 in Sundsvall (Sundsvallsbron) and the purification of this microplastic in a stormwater treatment system. The study is the first worldwide to evaluate treatment in such stormwater filters for highway runoff.
