Abstract : The feasibility of using grasses, yellow nutsedge (Cyperus escalantus), Indian grass (Sorghastrum nutans) and big bluestem (Andropogon gerardii) in the clean-up of propellant contaminated soil was assessed by performing hydroponic and soil experiments. The propellants 2,4-dinitrotoluene (2,4-DNT), perchlorate and nitroglycerin (GTN) often contaminate firing ranges due to partially detonated ordnances and incomplete combustion of munitions. In hydroponic experiments, sorption of 2,4-DNT to roots was significant in the grasses. Perchlorate accumulated in large amounts in leaves of the grasses with maximum accumulation in yellow nutsedge (732 mg kg-1). GTN was removed from the solution rapidly and almost 100% degradation was seen in all grasses within 52 hours. From soil experiments, it is evident that yellow nutsedge was effective in degrading 2,4-DNT. Perchlorate was accumulated in leaves of yellow nutsedge and Indian grass and GTN degradation was nearly 100% in Indian grass. Degradation in perchlorate and OTN was by bacteria.
