Abstract

Pore waters which were taken from sediments of the Chesapeake Bay were analyzed to determine the presence of volatile amines. A purge-and-trap technique was used to concentrate the amines. Then, following derivatization with heptaflourobutyric anhydride, the HFBA-amines were analyzed by gas chromatography with electron capture detection and with mass spectrometric detection. One secondary amine, diethylamine with a concentration of 0.3-0.6 uM, was found in a total of three pore water samples from cores collected on two different dates. A primary amine, sec-butylamine with a concentration of O. 05 AIM, was also found in one of these same samples. Another primary amine, n-propylamine with a concentration of 0.07 u.M, was found in two of the same samples in which these other amines were detected. Two amines, i-propylamine and piperidine, were detected with electron capture detection but the identifications of these two amines could not be confirmed by GC/MS analysis. The origin of these amines is unknown.
