Abstract:	Purpose Abiotic dechlorination of organochlorine pollutants seems to occur more efficiently in nature than previously thought. Ferrous (Fe²⁺) and sulfide (S²⁻) ions have been shown to be effective dechlorinating reagents. However, little is known about the interactions between Fe²⁺ and S²⁻ during dechlorination of 1,1,1-trichoro-2,2-bis(p-chlorophenyl)-ethane (DDT) in soil, in spite of the fact that these ions co-exist in waterlogged soils.
