| Abstract: | Polychlorinated pesticides and herbicides are of important organic pollutants in soils owing to their poor biodegradability. Recently, the interfacial dechlorinating transformation of polychlorinated compounds has attracted a great attention in the field of soil environmental sciences. This paper reviews the abiotic dechlorinating reactions, respiration dechlorinating reactions, and the chemically and microbiologically interactive dechlorinating reactions at the soil interface. The heterogeneous cycles of Fe(III)/Fe(II) species, and the dissimilatory reduction of iron oxides play vital roles during interfacial dechlorinating reactions. The mechanisms of chemically and microbiologically interactive reactions are discussed. The interfacial dechlorinating transformation interacts with some important soil chemical processes and plants rhizosphere processes. This paper provides some new insight for the study of soil chemically and microbiologically interactive reactions of dechlorinating transformation in China.
