Atmospheric electricity and quality of air

The volume electric charge and the mobility of atmospheric particles from 1 to 1000 nanometers in size are considered as a basis for an assessment of quality of air. In article there is shown that the stable aero disperse system (aerosol) including such forms as a room smog is formed when symmetrically loaded atmospheric ions interacting with relatively large negatively charged particles of atmospheric pollution. Speed (time constant) of such interaction is estimated. Analytical approach for an assessment of spectral distribution of mobility of atmospheric particles on the basis of the volt-ampere characteristic of the aspiration condenser is also considered. The computational techniques enabling to determine distribution parameters are offered.
