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. In the method of determining the metal concentration in the formed particles, information on the Physico-chemical properties of the particles is given. Metals in road dust are increasingly being studied and this is primarily in climate action. In this research, road dust particles formed on the surfaces of asphalt-concrete roads with different compositions in the Jizzakh region were studied. Based on this, the developed research methodology made it possible to comprehensively evaluate the distribution and size of particles generated as a result of car acceleration, constant speed movement and car braking.
