The toxicity of 2,4,6-trinitrotoluene (TNT) and its metabolites to Populus sp.
This research will study the phytoremediation of 2,4,6-trinitrotoluene (TNT) ammunition wastes using hybrid poplar trees. Studies will concentrate on phytoremediation using Imperial Carolina (Populus deltoides nigra DN-34) for terrestrial/uplands treatment of TNT wastes, by investigating the phytotoxicity of TNT and its two primary metabolites 2-amino 4,6-dinitrotoluene (2A) and 4-amino 2,6-dinitrotoluene (4A). These treatability studies will lead to preliminary design calculations for TNT contaminated soil and groundwater treatment systems. In particular, the results of this research will help assess the impact of poplar hybrids at an Iowa Superfund site located at Middletown, Iowa.
