Abstract

A laboratory study was conducted to determine whether tetryl (2,4,6-trinitrophenlymethylnitramine) contaminated soil could be bioremediated using a sequencing batch soil slurry reactor (SBR) operated under anoxic–aerobic sequence. The results indicated that tetryl was co-metabolically converted to aniline under anoxic conditions with molasses as the growth substrate. The gas chromatographic/mass spectrometric analysis of the soil slurry showed various metabolites, identified as trinitrobenzeneamine, dintrobenzenediamine, nitroaniline and aniline. Aniline was not metabolized further under anoxic conditions. When the soil slurry reactor was operated under aerobic conditions, the aniline concentration was reduced to below the detection limit (0.05 ppm). This metabolic conversion of tetryl is probably of value in the treatment of tetryl-contaminated soil and ground water, such as those found at the Joliet army ammunition plant site in Illinois and the Iowa army ammunition plant site in Burlington, Iowa.
