[The mechanism of action of aerosol disinfection]

It is drawn up a list of physical laws describing the behavior of an aerosol system. First the influence of sedimentation, diffusion, coagulation and impaction is described. In the second part the evaporation and the condensation from droplets in relation to the vapor tension of disinfectants is regarded. Finally the circumstances under which the vaporized disinfectants will reach the microorganisms by diffusion are described. It is demonstrated, that the terminus technicus "aerosol disinfection" should be restricted to systems, that operate with drop diameters less than or equal to 10 microns.
