Emission factors for 2009 for heavy metals (HM) are presented in Annex
2A-4. The appendix includes references and time-series. The emission
factors refer to:
• Two emission measurement programs carried out on Danish decentralised
CHP plants (Nielsen et al. 2010; Nielsen & Illerup, 2003).
• Implied Emission Factors for power plants based on plant specific
data reported by the power plant owners.
• Research concerning heavy metal emission factors representative
for Denmark (Illerup et al., 1999).
• A CONCAWE study (Denier van der Gon & Kuenen, 2009)
• Data for Danish natural gas (Gruijthuijsen (2001), Energinet.dk
homepage)
• Emission factors without national reference all refer to EEA (2009).
Time-series have been estimated for coal and for municipal waste incineration.
For all other sources the same emission factors have been applied
for 1990-2009.

Emission factors 2009 for PAH are shown in Annex 2A-4. The appendix
includes references. The PAH emission factors refer to:
• Research carried out by TNO (Berdowski et al., 1995).
• Research carried out by Statistics Norway (Finstad et al., 2001).
• An emission measurement program performed on biomass fuelled
plants. The project was carried out for the Danish Environmental
Protection Agency (Jensen & Nielsen, 1996).
• Two emission measurement programs carried out on Danish decentralised
CHP plants (Nielsen et al. 2010; Nielsen & Illerup, 2003).
• Additional information from the gas sector (Jensen, 2001).
• For residential wood combustion country specific emission factors
have been aggregated based on technology distribution in the sector
(Illerup et al., 2007) and guidebook emission factors (EEA, 2009).
Emission factor time-series have been estimated for residential wood
combustion, natural gas fuelled engines, biogas fuelled engines and
MSW incineration plants. All other emission factors have been considered
constant from 1990 to 2009. In general, emission factors for PAH
are uncertain.

Emission factors 2009 for dioxin are shown in Annex 2A-4.
The emission factor for residential wood combustion refers to technology
specific emission factors (EEA 2009; DEPA 2010) and to updated
technology distribution data (Illerup et al., 2007).
