Studies on the Biodegradation of Ordnance-Related Hazardous Waste, Phase II: Soil Degradation Kinetics.
Abstract
Aerobic degradation studies were conducted for four nitrate ester compounds: Nitroglycerine or Glycerol Trinitrate, Propylene Glycol dinitrate (PGDN), Triethylene glycol dinitrate (TEGDN) and Trimethyloethanetrinitrate (TMETN). Soil microcosm reactors were designed, assembled and operated to acclimate the soil microbiota to a mixture of the four selected nitrate ester compounds. Uncontaminated forest soil with low organic carbon was used in all studies. Carbon dioxide evolution measurements were made to monitor the acclimation process. Initially, the carbon dioxide evolution in the contaminated microcosm reactor was higher than the control (uncontaminated) microcosm reactor. However, after 42 days, the rate of carbon dioxide evolution in the two microcosm systems became nearly equal indicating the acclimation period. Results reported here demonstrate that soil microbiota can be acclimated to all four nitrate ester compounds at a concentration of 100 mg/L. This indicates that soil contaminated with nitrate ester compounds can be treated successfully in a soil slurry reactor.
