EFFECTS OF FIRE INTENSTIY ON THE MOLECULAR STRUCTURES OF DISSOLVED BLACK CARBON
EMSL Project ID
48530
Abstract
The proposed research will use Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) to determine the molecular composition of aromatic carbon-rich dissolved black carbon (DBC). Six samples of DBC extracted from pyrogenic organic matter (PyOM) experienced with different fire intensities will be examined. The FT-ICR MS derived data on the composition of DBC will be used along with data derived from UV/VIS spectroscopy, fluorescence spectroscopy, and disinfection byproduct formation potentials in order to evaluate the drinking water safety and chemical characteristics of dissolved organic matter (DOM) exported from fire-disturbed forested watersheds. The results from FT-ICR MS will provide solid evidence that different types of DBC could be generated from forest fire and the types of aromatic compounds in DBC could be fire temperature dependent. Results will also support a NSF CAREER proposal for a more detailed DBC characterization.
