摘要: Abstract A mobile pollutant measurement laboratory was designed and built at the Paul Scherrer Institute (Switzerland) for of on-road ambient concentrations a large set trace gases aerosol parameters with high time resolution ( −3 , additional peak particle number up to 400 000 cm . The regional background total concentration not found significantly correlate distance traffic anthropogenic emissions carbon monoxide nitrogen oxides. On other hand, this correlation significant particles in size range 50–150 nm, indicating that is better indicator than concentration. Particle distribution measurements showed daytime urban air dominated by ultrafine (nanoparticles) diameters
