2,3,7,8-Tetrachlorodibenzo--dioxin Dechlorination is Differentially Enhanced by Dichlorobenzene Amendment in Passaic River, NJ Sediments.

Polychlorinated dibenzo--dioxins (PCDDs) are a class of toxic organic compounds released by a number of industrial processes. Sediments of the Passaic River in New Jersey are contaminated by these compounds. To explore the ability of native organohalide respiring bacteria to dechlorinate PCDDs, we first enriched bacteria from sediments of the Passaic River on two organohalides, trichloroethene (TCE) and 1,2-dichlorobenzene (DCB).
