Abstract

This study examined the range of carbon and hydrogen isotopes within a global set of gasolines to investigate the potential and limitations of isotopic analysis within environmental assessments of gasoline-contaminated sites. Bulk carbon and hydrogen isotope signatures within gasolines from the study had a range greater than 8 parts per thousand and 85 parts per thousand, respectively. The combination of both isotopes produced a highly discriminating two-dimensional (2D) isotope fingerprint, highlighting the potential of 2D fingerprinting to differentiate gasoline sources. Compound-specific carbon isotope analysis was also completed to investigate its application as a method for risk-based management and environmental forensics.
