Occurrence of Traffic-Derived Microplastics in Different Matrices in the Road Environment

Abstract

The prevalence of microplastic contamination has raised concerns about the potential risk andimpact on the global environment. Traffic-derived microplastics, i.e., tire wear particles (TWP),polymer-modified bitumen, and road markings contribute to the emissions, and TWP areassumed to be one of the largest sources of microplastic emissions. Due to analyticaldifficulties, there is still a knowledge gap regarding transport routes, environmentalconcentrations, and toxicity. This thesis aims to investigate the occurrence of traffic-derivedmicroplastics in several traffic environments and thereby increase the understanding of theparticles
