Identification of the Minor Chemical Elements in the Particulate Matter Exhaust Emissions From In-Use Diesel Engine Passenger Vehicles

In this research, we investigate the minor chemical elements contained in the particulate matter (PM) exhaust emissions, generated by in-use diesel engine passenger vehicles. For this purpose, we apply a high-resolution optical emission spectroscopy technique, for precise, spectrochemical analysis of diesel particulate matter (DPM). By means of the laser-induced breakdown spectroscopy analytical method, we analyse PM from different road diesel engine vehicles. DPM were obtained from miscellaneous in-use diesel engine passenger vehicles of diverse types and models from major brand car producers in Europe. We analysed particulate matter extracted from the exhaust manifold part, from 67 different passenger vehicles, which are used in daily life environment.
