In recent years, with an increasing number of ground vehicles with internal combustion engines, the need for fuel, including motor gasoline, has increased significantly. It is known that during the operation of vehicles, a large number of exhaust gases are emitted into the atmosphere, containing such substances as carbon oxides, nitrogen oxides and benzapyrenes. The main source of education benzapyrene are aromatic hydrocarbons, primarily benzene. In this regard, the content of aromatic hydrocarbons in motor gasoline is subject to strict environmental requirements Euro-5. As the object of research was taken gasoline AI-80. All studies were conducted in accordance with State standards and generally accepted practical guidelines for the analysis of petroleum products.
