and no correlation seems to be present. Since there are no other available
data on the subject of pets, it is concluded that there are no surrogate data
available. The activity data for the period of 1980-1997 are estimated by en
expert judgement. The estimated data are shown in Table 7.7, Figure 7.3 and
Annex 2D Table 2D-2.

The Guidebook, 2009 (EEA, 2009) is the only available source to emission
factors for NMVOC, NH3, TSP, PM10, PM2.5 and PCDD/F. It also provides an
emission factor for PAHs but does not specify on the single compounds.
Chen et al. (2004) is the only available source to emission factors for the
heavy metals Cd, Cr, Cu, Ni, Pb and Zn.
The emission factors of the remaining compounds SO2, NOx, CO, As, Se,
HCB, PAHs and PCB are collected from the section on human cremation,
and it is assumed that humans and animals are similar in composition for
this purpose.
There is a good compliance between the emission factors for animal and
human incineration for PCDD/F and a relatively good compliance for
NMVOC, TSP, PM10 and PM2.5. The emission factors given by Chen et al.
(2004) for heavy metals are at least a factor 100 larger than those accepted for
human cremations with the exception of that of Zn, which is much higher
for the incineration of corpses.
No data was available for the emission of Hg in animal cremations. The
emission factor accepted for human incineration is not accepted in the case
of Hg, because the Hg emission from human cremations primarily stems
from tooth fillings.
