Particulate and gaseous atmospheric components have been sampled using a multiple-filter system. A Teflon filter for particle collection preceded four 7LiOH/glycerol treated Whatman-41 filters in a stacked filter arrangement. Up to fifty elements were detected on the particulate filter, while ten elements (B, N, S, Cl, As, Se, Sb, Br, I and Hg) were observed on the base-treated filters using the combined techniques of PGAA, INAA and IC. The base-treated filters proved to be very efficient collectors of the acidic gas-phase species, but apparently allow some elemental and organic species to pass through as shown by studies with activated charcoal-impregnated filters. Application of observed concentrations of atmospheric particles and acidic gases are compared to the results predicted by a hybrid receptor model.
