Respirable particulates generated by pressurized consumer products. I. Experimental method and general characteristics

Abstract

Many products and materials are available in the widely used pressurized package or “aerosol” form. A simulated breathing zone model approach has been developed and used to characterize the particles to which a user may be exposed. Some products characterized under simulated “worst reasonable” conditions produced concentrations of particulates smaller than 6 µm aerodynamic diameter exceeding 50 mg/m³.
