ABSTRACT
The release of 1,2,3-trichloropropane to the environment can occur through its manufacture, formulation, and use as an organic solvent. In the atmosphere, reaction with photochemically produced hydroxyl radicals should occur with an estimated half-life on the order of fifteen days. 1,2,3-Trichloropropane is used in small proportions as a crosslinking agent in the synthesis of polysulfides, in the synthesis of hexafluoropropylene, as a paint and varnish remover, solvent, and degreasing agent, which may result in environmental release. It is also found as an impurity in nematicides and soil fumigants. The vapor pressure for 1,2,3-trichloropropane combined with the Henry's Law constant and low Koc, suggest that volatilization from soil should be an important fate process. 1,2,3-Trichloropropane has been qualitatively identified in small-scale and large-scale retrospective studies in Californian and Hawaiian soil samples.
