The use of biological isotope fractionation in residual hydrocarbons was studied to evaluate its applicability in monitoring bioremediation. Enrichment in 13C was observed in the analysis of the stable isotope ratio in the residual content of three hydrocarbons (benzene, toluene and styrene) biodegraded in the laboratory. A correlation between residual hydrocarbon concentration and the stable isotope ratio was found. Field data taken from sites at a petrochemical facility, leaking underground storage tank and river sediments in Canada generated results similar to the laboratory study. The changes in 13C appeared to be unique to specific hydrocarbons and environmental conditions.
