Acetone biomass burning emission

Karl et al. detected VOCs at the Mauna Loa Baseline Station in March/April 2001 and thought that the abundance of acetone seemed to be partly influenced by biomass burning and domestic biofuel emissions [91]. It was revealed that secondary production of acetone and methanol in fire plumes over the Mediterranean could also be thought as characteristic biomass burning signatures, and the emissions of 25-31 and 29-35 Tg/year for acetone and methanol were estimated, respectively [87]. 

As part of the Megacity Initiative Local and Global Research Observations (MILAGRO) project, a comprehensive airborne study by Yokelson et al. reported the first detailed field measurements of biomass emissions in the Northern Hemisphere tropics [169]. Volatile emissions were measured from 20 deforestation and crop residue fires on the Yucatan peninsula. This included two trace gases which are often considered to be useful as indicators of biomass burning. One we have discussed before, namely acetonitrile, and the other is hydrogen cyanide. A variety of instrumentation was co-deployed for this investigation (FTIR spectroscopy, GD-FID, a GC-Trace Analytical Reduction Gas Detector, fluorescence and chemiluminescence instruments and various other spectrometers). PTR-MS was used to monitor methanol, acetonitrile, acetaldehyde, acetone, methyl ethyl ketone, methyl propanal, hydroxyacetone plus methyl acetate, benzene and 13 other volatile species.
