title: [The characteristics of the biological action and regulation of submicroscopic aerosols in the industrial environment].
abstract: Biologic action was studied of the silicon nitride powder with varying disperse composition. When producing and using the silicon nitride powder on an enlarged scale one must remember of its higher toxicity and fibrogenicity. There is a need of employing some method of determination of the submicroscopic aerosol disperse composition under industrial conditions.
