Abstract : 2,4,6-Trichloroaniline (2,4,6-TCA) is not a contaminant of the estuarine sediments of the Edgewood Arsenal area of the Aberdeen Proving Ground (APG), MD. This conclusion was reached through a study of the environmental fate of 2,4,6-TCA and by direct analysis of sediment samples. 2,4,6-TCA is soluble in water (mg/L) to the extent of 32 mg/L at 19C, and is degraded by sunlight. The compound is also lost rapidly by evaporation from water. Analysis of sediments by gas chromatography/mass spectrometry showed two major substances; 2,4,6-trichloroaniline and 2,4,6-trichlorophenylisocyanate, in nearly equal concentrations. It was found that these substances arise by pyrolysis of N,N'-bis(2,4,6-trichlorophenyl) urea. This occurs when the urea is injected into the hot (250 C) injection port of the gas chromatography. The presence of N,N'-bis(2,4,6-trichlorophenyl) urea was also confirmed by high pressure liquid chromatography.
