Tire and road wear particles (TRWPs) are one of the main sources particulate traffic emissions, but measured data on TRWP contents in environment scarce. This study aims at identifying organic compounds suitable as quantitative markers for TRWPs by a tiered multistep selection process involving nontarget screening subsequent identification liquid-chromatography high-resolution mass spectrometry. Starting from several thousands signals recorded extract tire particles, rigorous considered source specificity, tendency leaching, analytical sensitivity precision, stability during aging. It led to three transformation products
