Quantitative microprobe and scanning electron microscope (SEM) analyses of individual particles are important for determining chemical speciation in atmospheric aerosols; possibly of even greater significance are their application for characterization of emissions from specific point sources of aerosol particles. We present, as an example, results of a study of the emissions from the secondary iron foundries in Phoenix, Ariz. The goals of this study were threefold: (1) to characterize the particle emissions from the foundries, (2) to link particle types to the specific steps in the foundry processes that produce them, and (3) to establish criteria for distinguishing between emissions from the two foundries.
