Development of Methods for Sampling and Analysis of Polychlorinated Naphthalenes in Ambient Air Mitchell D. Erickson", Larry C. Michael, Ruth A. Zweidinger, and Edo D. Pellizzari Research Triangle Institute, P.O. Box 12194, Research Triangle Park, N.C. 27709
A procedure and sampler to collect and analyze for polychlorinated naphthalenes (PCN's) in ambient air were developed. PCN's were collected on a glass fiber filter (GFF) and two precleaned polyurethane foam (PUF) plugs in tandem. PCN's were triply extracted from PUF and GFF with toluene a t 25 "C. Samples were analyzed by quadrupole gas chromatography/mass spectrometry/computer (GC/MS/COMP) in the multiple ion detection (MID) mode, permitting detection of
