title: Respirable particulates generated by pressurized consumer products. II. Influence of experimental conditions.
abstract: The many products available in pressurized packages produce appreciable concentrations of particulates that may be deposited in the deep lung of human users. We have reported the size and concentration characteristics of these aerosols under carefully standardized conditions in a previous paper. These standard conditions have been varied to determine the influence of product discharge conditions on observed aerosol characteristics. The size characteristics are relatively insensitive to a wide range of changes in the discharge conditions; the only significant effect observed followed changing the target of the spray from a steel plate to a wig. The aerosol concentrations were changed by several experimental factors, but the relative changes were less than the estimated relative range of human exposure.
