Phytoremediation processes, using plant species such as parrot feather Myriophyllum aquaticum)... 

Terrestrial and aquatic vascular plants promote the biological reduction of nitro groups on TNT to amine groups, yielding 2-ADNT and 4-ADNT, similar to invertebrates and vertebrates [13]. In vascular plants, the putative reduction enzyme is a nitroreductase [44], During reductive TNT biotransformation, ADNT products are accumulated within the plant tissue or excreted to the surrounding culture medium. For Myriophyllum species, the excreted ADNT products accounted for less than 20% of the initial TNT, and only trace levels of free ADNT remained in the biomass [37,38,42], One study [40] also showed that M. aquaticum was capable of oxidative transformation of TNT via methyl oxidation or aromatic hydroxylation, with oxidation products accounting for nearly 36% of the TNT initially added.
