Determination of novel aromatic amines in environmental samples by gas chromatography/mass spectrometry

A number of compounds belonging to five chemical classes of aromatic amines were identified by electron impact mass spectrometry, both in the vapor ph ase and in suspended particulate matter collected in an area subjected to h eavy traffic. This paper presents the mass spectra of new aromatic amines, proposed mechanisms for formation of the major ions obtained by electron im pact, concentrations of each class in 13 environmental samples, and the dis tribution of the individual compounds of the major chemical classes (greate r than 80% by weight).
