Can levoglucosan be used to characterize and quantify char/charcoal black carbon in environmental media?

The study demonstrates that levoglucosan can serve as a good qualitative indicator for the presence of char produced under low temperature conditions in soil, sediments, and ultrafine aerosols. Although levoglucosan is not a proper quantitative proxy for char BC content in the environment, this molecular marker has a unique role in the current BC methods continuum because it traces combustion material often missed with most oxidation-based methods.
