Chemical Characterization and Toxicologic Evaluation of Airborne Mixtures. The Chemical and Physical Characterization of Phosphorus Smokes for Inhalation Exposure and Toxicology Studies
Abstract
The chemical and physical properties of the aerosols produced from the combustion of red phosphorus containing butyl rubber (RPBR) and white phosphorus impregnated in felt (WPF) have been examined, The aerosols were produced at a uniform concentration by extruding softened raw material and burning the emerging filament or by igniting fragments of the formulations in a convective air flow. Aerosol particle sizes were found to be within the respirable range, varying from 0.4 to 1.0 micrometer depending upon generation conditions and aerosol age at collection, Chemically, both RPBR and WPF aerosols were found to be very similar, composed primarily of water and phosphoric acids. Organic compounds and inorganic gases were detected only at trace levels. Keywords include: Combustion products; and Phosphoric acids.
