| Abstract |
After application of mustard gas (HD) to the soil surface, its possible fate follows evaporation, absorption, and degradation. Using a laboratory-sized wind tunnel, thermal desorber in combination with gas chromatograph-mass spectroscopy (GC-MS), and 13C nuclear magnetic resonance, systematic analysis of the fate of HD was performed. The results show that a drop of neat HD deposited on the soil surface evaporated slowly while being absorbed immediately into the matrix. The initial evaporation or drying rates of the HD drop were power-dependent on its initial drop volume with the smaller drops evaporating relatively quicker. HD absorbed into the soil remained for a month, degrading eventually to nontoxic thiodiglycol via hydrolysis through the formation of sulfonium ions. |
