MASS SPECTROMETRY OF NANOPARTICLES.

Nanoparticles with diameters from 10 nm to 1000 nm were analyzed using the scanning mobility particle sizer (SMPS) continuously from October 2020 till May 2021. Mass spectrometry was performed in 129 channels. Measurements of some other air pollution parameters were used for comparison and analysis. A large number of nanoparticles was detected in the period of strong air pollution, as expected. However, a surprisingly large number of nanoparticles was detected in spring and summer, where other parameters of air pollution were good. [ABSTRACT FROM AUTHOR]
