NON-EXHAUST EMISSIONS OF ROAD VEHICLE: QUANTITATIVE AND MORPHOLOGICAL ANALYSIS

Abstract

Pollution in large cities is a recurring problem which governments and private companies are trying to answer. Control pollution issued by vehicles is a regularly expressed element, but this concerns the case of pollutants from exhaust emissions, non-exhaust emissions are very rarely studied. The non-exhaust emission sources include brakes, clutches, tires, road and resuspension of particles on road. These different elements emit particles due to their wear by abrasion, corrosion or even tear. These sources contribute to the concentration of particles in the atmosphere with some differences of chemical characterizations, sizes and quantities. This article presents our project and the first experiments and some results
