Өгүүллийн хураангуй: Have been studied particle sizes and their distributions along the automagistrals in Ulaanbaatar city by means of Photon Cross-correlation Spectroscopy (PCCS) using the equipment NANOPHOX (Sympatec GmbH, Germany). Have been determined mean diameters (x0), size distribution ranges, specific surface area (Sv) of aerosol particles to be equal, correspondingly, to (1.1±3)÷(2.5±3) mm, 74 nm÷4.0 mm and 2.38÷5.43 m2/cm3. In the 790 nm÷3.8 mm range the particles distributed with density values 0.02÷8.15 (q3lg) having Gaussian symmetry. Have not been observed nanoparticles with diameters less than 74 nm. The samples contain 0.02% (volume persent) ultrafine particles or nanoparticles in the range of 74-100 nm diameters, 83.73% fine particles (PM2.5) in the range of 100 nm÷2.4 mm and 16.25% coarse particles (PM10) in the range of 2.4-4.0 mm. So it can be concluded that in the automagistral aerosol samples previal PM2.5 particles.
