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.
