TO THE QUESTION OF PAH IDENTIFICATION GENESIS IN URBAN FUEL, WITH USING GEOCHEMICAL MARKERS

The paper presents data on the use of indicator ratios based on the nature of the concentration ratios of Polycyclic Aromatic Hydrocarbons (PAHs) to identify sources of environmental pollution by petroleum hydrocarbons. The identification of the assessment of the effectiveness of the indicator ratios used is shown. Based on the indicator ratios presented, the possibility of identifying pyrogenic PAHs in automotive fuel and other fuels and lubricants is considered.
