Humic acids as electron acceptors for anaerobic microbial oxidation of vinyl chloride and dichloroethene.
Anaerobic oxidation of [1,2-14C]vinyl chloride and [1, 2-14C]dichloroethene to 14CO2 under humic acid-reducing conditions was demonstrated. The results indicate that waterborne contaminants can be oxidized by using humic acid compounds as electron acceptors and suggest that natural aquatic systems have a much larger capacity for contaminant oxidation than previously thought.
