Abstract
The difference in chemistry between interstitial aerosol particles and particles that were scavenged into fog droplets is examined using multivariate statistical techniques. 15 trace elements (P, S, Cl, K, Ca, Cr, Mn, Fe, Ni, Cu, Zn, Se, Br, Pb, EC) were used in the analysis. There was a significant difference in composition between the two types of particles. S, Fe, Mn, and Cu were among the elements best describing the scavenged aerosol, while the interstitial aerosol was best described by elemental carbon (EC).
