Abstract:

Procedures are presented for qualitative screening and subsequent quantitation of munitions and related compounds present at sites contaminated by open burningopen detonation OBOD disposal of munitions. Methods were developed to recover munitions and polycyclic aromatic hydrocarbons PAHs from soil via sonic extraction into acetonitrile, and munitions from water via trapping onto C18 disposable cartridges and eluting with methanol. Complementary HPLC procedures were used for identification and quantification of these compounds. A qualitative High Performance Liquid Chromatography HPLC gradient method was developed, and used to screen samples for a wide range of munitions and PAHs. Quantitation of munitions and their environmental reduction products was accomplished using an HPLC isocratic method. Recoveries of munitions and degradation products spiked into sandy loam soils were greater than 90 in all cases. Corresponding recoveries from aqueous samples were comparable for the nitroaromatics, but were poorer for the nitramines.
