Advanced analysis of solid particles
The automotive industry is one of the fastest developing businesses in the global scale. Currently there is about 1 billion of light-duty and passenger vehicles on the roads, most of them are powered by the gasoline engines . One observed that vehicles emit a vast amount of the pollutants, that negatively affect health and life span of living organisms including humans. The presentation is focused on the analysis of chemical and physical properties of the solid particles collected on the 47 mm filter from the dynamometer chassis. Based on the previous work  the Authors present  several analytical techniques, used to the study of the emissions of the non-regulated components such as PAHs adsorbed on the solid particles. The selected results from Euro 6-compliant vehicles will be presented. The analysis of the composition of particulate matter (PM) can be achieved with methods such as Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Ion Chromatography (IC) or Gas Chromatography with Mass Spectrometry (GC/MS). Due to the limited sample size selected methods have to provide as much information as possible. The wide range of results of the measurements will be useful in establishing the direction of the further research leading to the decrease of negative impact of the vehicle emissions on the health and environment.
