摘要: Abstract Road dust is a non-exhaust source of atmospheric particulate by re-suspension. It composed particles originating from natural sources as well other such tire, brake and asphalt wear. The discrimination between directly emitted abrasion process those related to re-suspension therefore an open issue, far the percentage contribution emissions becoming more considerable due also recent policy actions technological upgrades in automotive field, focused on reduction exhaust emissions. In this paper, road collected along bridge that connects Venice (Italy) mainland characterized with multi-technique approach order determine its composition depending environmental traffic-related conditions. Six pollutant were identified cluster analysis: brake, railway, asphalt, soil + marine, mixed combustions. Considering lack information matrix area, study intended provide useful for future identification particulate.
