Methods of determining the amount of harmful particles released into the environment as a result of car tire wear

Abstract This article describes determining methods of metal emissions in the composition of small particles coming by brake mechanisms details and tire wear as a result of vehicle movement, and dust to be formed by comparative analysis on asphalt-concrete roads of different compositions. A significant contributor to particulate matter in cities is traffic-related sources. Traffic-related particles can be divided into exhaust particles released by the incomplete combustion of fuel and the volatilization of lubricants during combustion and formed by brake mechanism parts, tire wear and road surface wear, and accumulated due to turbulence caused by road traffic. The method of determining the metal concentration in the formed particles gives information on the physico-chemical properties of the particles.
