Annual Danish informative inventory report to UNECE. Emission ...

NAEI (2007) is the only source that provides data for PAHs, and that
gives an emission factor for NMVOC. The total PAH emission factor
sums the emissions of: benzo(b)flouranthene, benzo(k)flouranthene,
benzo(a)pyrene, indeno(1,2,3-c,d)pyrene and benzo(ghi)perylene.
Being that Persson et al. (1998) and Blomqvist et al. (2002) are the only
sources to a SOx emission factor, Blomqvist et al. (2002) is the best available
source as this provides a more recent and more detailed method.
Emission factors for NOx and CO are provided by several sources EIIP
(2001), Persson et al. (1998), Blomqvist et al. (2002), Claire (1999) and
NAEI (2007). In the case of both compounds there is a good compliance
between the emission factors provided by EIIP (2001), Claire (1999) and
NAEI (2007). And in both cases the more recent factors of NAEI (2007)
are selected.
No data was available for HCB and PCB. NH3 is assumed not to be
emitted.

In the process of selecting the best reliable emission factors for the calculation
of the emissions from Danish vehicle fires, a range of different
sources have been studied. Unfortunately it is difficult to do an interrelated
comparison of the different sources because they all establish
emission factors on different assumptions and many of these assumptions
are not fully accounted for. Table 7.26 lists the accessible emission
factors and their respective references.
