The effectiveness of the International UN Regulations on environmental safety of vehicles

Abstract

The article considers the modern problems of atmosphere pollution in the large cities. The official discussion of a new urban air pollution problem put forward by the Russian Federation has been analyzed. The new problem was caused not only by the gas exhausts but by the wear of tires and roads surface.The quotations from speeches made by the representatives of different countries and organizations were cited and analyzed. The authors came to a conclusion that in the environment the particles of worn tire treads did not exist in isolation. In fact, they were always mixed with at least pavement particles, thereby reducing the rubber weight in the solid fraction. It was stressed that the choice of methods used for the detection of particles was also an acute problem. The comparative materials of the research carried out at FSUE “NAMI” on the values of PM 10 and less emitted by vehicles in urban conditions on the example of the city of Moscow were given as well as the forecast estimation of their exhaust up to 2030. The studies showed that solid particles emissions caused by worn tires and braking systems were nowadays 10 times greater than the solid particles emissions made by diesel engines when compared to Euro-6 standards adopted in Europe. On the basis of the materials presented in the article, it can be stated that there is a serious problem that has not been given attention before - the pollution of the urban air environment by products of tire wear and brake mechanisms, leading to the formation of smog in major European cities.
