Selected organic compounds can undergo abiotic reduction in anaerobic sediment systems. The factors that govern these reactions are not well defined, but the chemistry and the biology are strongly coupled. No ideal methodology is now available to quantitatively separate the contribution of the biological processes from the chemical processes. In fact, to rigorously model redox processes, it may be necessary to model additional processes that take into account bio-organic and bio-inorganic reactants produced as a result of microbial activity. Sediment-associated reducing agents responsible for reduction in the studies are not known. The identity, as well as the activity, of the reducing agents is required to develop quantitative expressions that describe abiotic reduction. A working model has been suggested to account for the observations reported for the abiotic reactions.
