Abstract (english): The biodegradation of volatile fully chlorofluonnated hydro carbons (CFCs), partly chlorofluorinated hydrocarbons (H CFCs) and vinyl chloride (VC) were investigated in compost and marl in laboratory studies. Trichlorofluoromethane (R11), dichlorodifluoromethane (R12), 1,1,2-trichlorotriflu oroethane (R113), difluoromethane (R32) and VC were bio degradable in compost under anaerobic conditions, probably by methanogenic bacteria. The anaerobic decomposition products of R11 were dichlorofluoromethane (R21 ) and chlo rofluoromethane (R31). The degradation product of R12 was chlorodifluoromethane (R22). R11 and its degradation prod ucts have the inhibiting effects of the R12 degradation under anaerobic conditions. The partly halogenated hydrocarbon R22 and VC were degraded preferentially under aerobic con ditions in marl, probably by methanotrophic bacteria. Under aerobic conditions R22 and VC have inhibited the biodegra dation of methane by methanotrophic bacteria.
