Persson et al. (1998) and Lemieux et al. (2004) delivers very similar emission
factors for NOx, the more recent Lemieux et al. (2004) is chosen as the most
reliable. Lemieux et al. (2004) is also considered the best available in the case
of PAHs.
Emission factors for CO are available from the same two sources and from
Lönnermark et al. (2004); in this case Lönnermark et al. (2004) and Lemieux
et al. (2004) deliver the same factor. Lönnermark et al. (2004) is chosen as the
best available source since it is based on experimental data.
No data was available for Hg, Se, HCB and PCB. NH3 is assumed not to be
emitted.
