![]() ![]() The number of TBMP ≥100 μm in the WDS samples was up to 2561 particles/L. ![]() ![]() The largest proportion of anthropogenic microplastics detected consisted of tire tread wear and bitumen. Sodium iodide (NaI) was found to be effective for density separation of TBMP. TBMP concentrations were operationally defined, using density separation for some samples, followed by analysis by stereo microscopy. ![]() On each of these occasions, and several occasions during a four-month period with frequent street sweeping, sweepsand and washwater, as well as flow-weighted sampling of stormwater, were collected. Road dust was sampled on the road surface using a wet dust sampler, before and after street sweeping on two occasions. The analysis also included plastic, paint and fiber particles. Here the concentrations of tire and bitumen microplastic particles (TBMP) on roads and in nearby in stormwater, sweepsand and washwater were measured for the first time within the same area and time period. However, more knowledge of the emissions and their further fate in the environment is needed, and the effectiveness and benefits of potential measures must be investigated to support future risk management efforts. Tire and road wear particles have been identified as a potential major source of microplastics in the environment. ![]()
