The article deals with the influence of the driving mode on the emissions of polycyclic aromatic hydrocarbons (PAH) from the exhaust gases of passenger cars in real road traffic. Measurements were carried out on vehicles of different emission categories and engine design types, while sampling took place on a route including urban, suburban and highway traffic. Particular attention was paid to PAHs bound to solid particles, whose concentrations were analyzed depending on driving dynamics in different driving modes. The results show significant differences in the emission profiles depending on the driving mode and the emission standard, which has significant consequences for the assessment of the environmental impacts of transport and the design of effective measures to reduce pollutant emissions from real traffic.

The influence of driving mode on polycyclic aromatic hydrocarbon emissions in real traffic conditions
This article deals with the influence of driving mode on polycyclic aromatic hydrocarbon (PAH) emissions from passenger car exhaust gases in real traffic conditions. Measurements were taken on vehicles of various emission categories and engine types, with sampling carried out on a route covering urban, suburban, and highway driving. Particular attention was given to PAHs bound to solid particles, whose concentrations were analyzed in relation to driving dynamics in different driving modes. The results show significant differences in emission profiles depending on the driving mode and emission standard, which has important implications for assessing the environmental impact of transport and designing effective measures to reduce pollutant emissions from real-world driving.
