Abstract
Non-exhaust fine particles such as tires and brakes emitted from vehicles have a significant impact
on air pollution and human harm, and regulations on emissions are being discussed in earnest,
starting with the introduction of brake wear particles emission standards in Euro 7. Various indoor
and outdoor experiments were conducted, such as analysis of the amount of wear on tires and
brakes, and analysis of the physical and chemical properties of fine particles, as fundamental data
for the introduction of emission standards and the development of low wear tires and brakes to
meet regulations. Recently, international standardized indoor experimental methods for brakes
have been announced, and indoor and outdoor experimental methods for tires have been
continuously studied to develop international standardized methods. In particular, tire-break-road
wear particles are usually mixed with each other in the non-exhaust particles from a vehicle driving
on real roads, and in-depth research is being performed on the accurate classification and
characteristic analysis. In this study, the characteristics of the volatile organic components (VOCs)
and marker substances for tire and tire-road wear fine particles were analyzed. A system capable
of measuring non-exhaust wear fine particles was installed on the vehicle, and samples were
collected from the vehicle running on the two different driving conditions, various constant speeds
in the proving ground road and real driving roads. The VOCs contained in tires and tire-road-wear
particles (TRWPs) under the specific temperature conditions with a thermogravimetric analyzergas chromatography/mass analysis (TGA-GC/MS). In addition, the correlations between VOCs
and tire rubber components were analyzed through marker analysis using pyrolysis-gas
chromatography/mass analysis (GC/MS). In VOCs, n-Hexane, n-Dodecane, and 1-Butene were
measured relatively much in both constant-speed and real-drive tests. In addition, marker
substances of synthetic rubber and natural rubber were not detected in the collected background
fine particles.
