"Chemical characterisation of fine particle emissions from woodstove combustion of common woods growing in mid-European Alpine regions";
Atmospheric Environment, 42 (2008), S. 126 - 141.

Woodsmoke samples derived from the combustion of beech, oak, spruce, larch and softwood briquettes in a closed stove
have been collected and analysed so as to derive chemical profiles for ambient particulate matter (PM) source
apportionment studies, for example, by CMB modelling. Trace metals, soluble ions, carbon species total carbon (TC),
elemental carbon (EC) and organic carbon (OC), anhydrosugars, polar and non-polar trace organics, cellulose and humiclike
substances (HULIS) have been measured. The inorganic and most organic components were not significantly different
for the different woods, so that one profile could be derived for CMB modelling. The anhydrosugar levoglucosan was
present in high concentrations, 4-15% w/w, and for the mix of woods important for Austria, one conversion factor can be
used to derive the mass of woodsmoke from the levoglucosan concentration in ambient air. Mannosan is also a major
component, 0.3-4% w/w, which, taken together with the levoglucosan content, permits estimates to be made of the
proportion of hard- and softwood smoke to ambient PM.
