Ultraviolet Light and Electron Beam Induced Degradation of Trichloroethene
Chlorinated hydrocarbons such as trichloroethene (TCE) and tetrachloroethene are widely used as solvents and degreasing agents. Emission of these volatile compounds causes considerable environmental pollution. In the extreme case of spillage by accident or criminal negligence, they quickly penetrate into the soil and the groundwater table on account of their relatively high specific weight compared to water and their fluidity. In the soil under anaerobic conditions, these compounds undergo bacterial degradation, prominent products being cis-1,2-dichloroethene and vinyl chloride whose carcinogenic potential is known (Nerger and Mergler-Völkl, 1988).
