Anaerobic degradation of diuron [3-(3,4-dichlorophenyl)-1,1-dimethylurea], monuron [3-(4-chlorophenyl)-1,1-dimethylurea], and fenuron [1,1-dimethyl-3-phenylurea] were studied. Herbicide containing media (reduced with cysteine-HCl and under 95% N2:5% CO2 gas phase) were inoculated with pond sediments. Sediment from a diuron-treated pond dehalongenated diuron to 3-(3-chlorophenyl)-1,1-dimethylurea (CPDU)
