The main attention was paid to the dehalogenation of organochlorine compounds. The research included chlorinated ethane’s and chlorinated methane’s. In the groundwater samples, the most common components from the group of chlorinated ethenes were determined, i. e. tetrachloroethene (PCE), trichlorethylene (TCE), dichloroethene (DCE) and vinyl chloride (VC) as well as typical components from the group of chlorinated methane’s, . tetrachloromethane (PCM), trichloromethane (TCM) and dichloromethane (DCM), were also made. |
