Analysis of 2,4,6-trinitrotoluene and its transformation products in soils and plant tissues by high-performance liquid chromatography
- Pacific Northwest Lab., Richland, WA (United States)
Previous studies have failed to provide an acceptable mass balance for 2,4,6-trinitrotoluene (TNT) in soils and plants due to deficiencies in analytical methodology. A high-performance liquid chromatographic (HPLC) method for soil analysis is reported which allowed for a mass balance in excess of 88% during a 2-month study. A method for plant analysis was developed which involved fractionation of organic extracts on Florisil adsorbent, to remove interfering pigments, followed by HPLC analysis of TNT and the primary metabolites, 2-amino-4,6-dinitrotoluene and 4-amino-2,6-dinitrotoluene. Chromatographic recovery of TNT from spiked tissues was 85{plus minus}6%. The methodology was utilized to investigate TNT uptake and metabolism in plants grown in TNT hydroponic solutions.
