Halogenated heterocyclic chemicals are widely used for manufacture of pesticides, pharmaceuticals, dyes, and explosives. Often they are environmentally mobile and can contaminate ground water reserves. Picloram, a broad spectrum herbicide, has a half life in the soil of as long as 1 year. This paper reports on the reductive dehalogenation of picloram in anoxic freshwater sediments, though not when sulfate or nitrate was available as a terminal electron acceptor, and its subsequent conversion to an unidentified product. 25 refs., 4 figs, 1 tab.
