SUBSTANCE: method includes collecting gases in a sampler and subsequent analysis of the sample material. The sampler is insulated from the ambient environment and a portion of distilled water is added, wherein a suspension of solid particles of the exhaust gas is formed by releasing said particles into said portion of water. Formation of the suspension begins after removing foreign dust and soot particles from the exhaust pipe that have settled there when the internal combustion engine is idle. During sample collection, the suspension is mixed and a sterile syringe is used to collect about 40 ml of liquid, which is then analysed on a laser particle analyser to determine particle size and shape distribution therein. Substance analysis of the suspension is then carried out on a light microscope and electron microscope with an energy-dispersion spectrometer for determining material composition of the solid particles and size and shape distribution of said particles.
