Abstract: Traditional studies of natural attenuation of halogenated hydrocarbons mainly focus on biodegradation process. However, recent studies have found that halogenated hydrocarbons can be geochemically reduced by the reactive minerals in the subsurface environment. This process is called abiotic natural attenuation of halogenated hydrocarbons. This article reviews the latest research progress on the abiotic natural attenuation of halogenated hydrocarbons mediated by natural reactive minerals. The reactive minerals that can reduce halogenated hydrocarbons include iron-sulfur minerals, iron oxide minerals and iron-bearing clay minerals. Among them, iron-sulfur minerals are the most abundant mineral in aquifers. The reaction pathways include dichloroelimination, hydrogenolysis, radical addition, radical coupling, dehydrohalogenation, and hydrolysis. Dichloroelimination and hydrogenolysis are the most important reaction pathways, especially for halogenated alkanes and halogenated alkenes. The chemical composition of abiotic degradation products mainly depends on the reaction pathway and the parent halogenated hydrocarbons. The reaction rate of various halogenated hydrocarbons reported in the literatures are compiled and analysed. The analysis of reaction rate data suggests that the reactivity of different minerals generally follows the trend: mackinawite≫pyrite > biotite > vermiculite≈green rust > magnetite≈montmorillonite. The reaction rate is also affected by factors such as the type of halogenated hydrocarbons, pH, sulfide concentration, coexisting metal ions, natural organic matter, and mineral morphology. Overall, current studies corroborate that reduction by reactive minerals is a key natural attenuation mechanism for halogenated hydrocarbons. However, there are still several critical knowledge gaps. It is still unclear about the relationship between the types of Fe(Ⅱ) in reactive minerals and their reactivity, the structural changes of Fe(Ⅱ) during the reduction of halogenated hydrocarbons, and the mechanisms of electron transfer from structural Fe(Ⅱ) to halogenated hydrocarbons. Current researches are mainly laboratory bench-scale studies while field studies are rare. Further field studies are necessary to confirm that the knowledge obtained through laboratory studies is consistent with field observations. Fluctuations in shallow water table would cause the reactive mineral exposure to dissolved oxygen. Reactions of the reactive minerals with oxygen generate hydroxyl radical (·OH) that can oxidize halogenated hydrocarbons. Further researches are needed in this area.
