On chemical composition of non-exhaust emissions being generated during automobile transport operation

Abstract

Introduction (problem statement and relevance). In the Russian Federation, automobile transport plays one of the key roles in the economy carrying out more than half of all passenger and cargo transportation. At the same time, its operation has a negative impact on the environment and population health, especially in the cities. This is largely due to the non-exhaust emissions containing hazardous cancerogenic substances. Therefore, a task of studying the chemical composition of these emissions arisesThe purpose of the study is to show the main components of the chemical composition of non-exhaust emissions, to assess the level of their relative toxicological hazard, and to develop the sampling procedure for tyre and roadway wear emissions.Methodology and research methods. On the basis of domestic and foreign materials, the method of system analysis of results of studies of chemical composition of non-exhaust emissions has been used.Scientific novelty and results. The main chemical components of non-exhaust emissions affecting the health of the population of large cities have been considered, the sampling procedure for particulate matters from tyre and roadway wear has been developed.Practical significance. The information on the main components of non-exhaust emissions affecting the health of the population of large cities has been summarized, the original sampling procedure for selective analysis of tyre and roadway wear products has been developed.
