Uptake and Transformation of TNT by Hybrid Poplar Trees

摘要: This paper examines the potential for using hybrid poplar trees to remediate sites contaminated with high explosive 2,4,6-trinitrotoluene (TNT). Laboratory experiments assessed uptake of [U-14C]TNT from both hydroponic and soil systems. TNT is strongly bound transformed by root tissues, it only translocates slightly leaves cuttings. was more bioavailable in system, but this did not affect distribution radiolabel among root, stem, or leaf tissues. The translocation found be similar that reported other plant species up 75% uptaken remaining tissues 10% eventually being translocated leaves. majority extractable less than 10 percent applied label identifiable HPLC/radiochromatograph. tree 4-amino-2,6-dinitrotoluene (4-ADNT), 2-amino-4,6-dinitrotoluene (2-ADNT), a number unidentified com...
