13. ABSTRACT (Maximum 200 words)
Samples of soil that had been aerobically composted or anaerobically digested were extracted with solvent, then
hydrolyzed with base and then acid. The concentrations of extractable TNT and its monoamino and diamino
transformation products fell rapidly after the first days of treatment. Hydrolysis of the solvent-extracted residues
released significant quantities of intact transformation products. The concentrations of RDX and HMX were re-
duced in a similar fashion without the appearance of significant quantities of transformation products. A general-
ized approach to biotreatment matrices analyses was developed. Spike-recovery studies indicated that analyses of
bioremediation matrices should be considered as a qualitative descriptor of the progress of humification and the
capacity to covalently conjugate transformation products rather than as a quantitative measure of the absolute
amounts of various analytes present.
