Additional information

A half life of 13.291 days is estimated for reaction of trichloroethylenewith hydroxyl radicals in the atmosphere at 25oC [AOPWIN Program, v.1.92].

Overall QSARs estimated half-life for degradation of trichloroethylenein air based upon AOPWIN Model is 108.5 hours.

Based on the data on photochemical degradation of trichloroethylenein the air, it is considered to degrade in the atmosphere via photooxidation process.
