Influence of particles formed resulting from wear of automobile brake mechanisms on human health

Abstract

In this article, details of the brake mechanism and the method of determining the concentration of metals in the particles formed from the wear of tires as a result of the movement of cars, as well as a comparative analysis of road dust formed on asphalt-concrete roads of different composition are covered. In cities’ traffic-related sources are a substantial source of particulate pollution. The following categories of traffic-related particles exist: brake mechanism details, formed as a result of tire wear and wear to the road surface, accumulate due to turbulence caused by traffic, and exhaust particles released as a result of incomplete combustion of fuel and volatilization of lubricants during combustion. The method of determining the metal concentration in the formed particles, data on the physical and chemical properties of the particles are presented. Information is given on the negative impact on human health of the particles formed as a result of wear of the details of the car brake mechanism.
