AbstractContamination of breathable air by particulate matter has becoming one of the challenging problems in urban agglomeration. Apart from nanoparticle generation by diesel engines, there is a number of non-exhaust sources, many of which related to triboemision due to abrasion and wearing of pavements, brake pads, tires and other materials and elements. This work describes a new technique, which has been developed for quanti-tative characterization of nanoparticle aerosols though experimental simulation on various scales from basic laboratory-scale tests to in situ real-life test. A new method for analysis of the nanoparticle emission rate has been developed on the basis of the model of bal-ance of nanoparticle flows. The model has been tested using natural airborne nanoparticles and artificial aerosols.
