Abstract :
Particle sizes and their distributions of aerosols along the road in Ulaanbaatar city were studied by Photon Cross Correlation Spectroscopy (PCCS) NANOPHOX (Sympatec GmbH, Germany). Mean diameter (x0), size distribution range, specific surface area (Sv) of aerosol particles are equal to 1.1÷2.5μm, 74nm÷4.0μm and 2.38÷5.43m2/cm3 respectively. On the other hand, particles distribution is Gaussian with density 0.02÷8.15 (q3lg) in the range of 790nm÷3.8μm. However, nanoparticles with diameters less than 74nm were not observed. The results reveal that samples contain 0.02% (volume persent) ultrafine particles or nanoparticles occur in the range of 74-100nm, 83.73% fine particles (PM2.5) occur in the range of 100nm÷2.4μm and 16.25% coarse particles (PM10) occur in the range of 2.4-4.0μm. It can be concluded that road aerosol sample contain high percent of PM2.5 particles.
