Figure 2.9 Cd emissions. Time series for 1990 to 2010 and distribution by main sector for 2010.
Mercury (Hg)
The largest sources of mercury (Hg) emissions to air are waste incineration
and coal combustion in energy industries. Due to improved flue gas cleaning
and decreasing coal combustion the emissions from Energy industries decreased
by 76 % from 1990-2000. Non-industrial combustion is dominated by
wood combustion in residential plants while emissions from the waste sector
mainly owe to cremation. The variations in emissions from industrial processes
owe to shut down in 2002 followed by re-opening and a second shut
down in 2005 of the only Danish electro-steelwork.

Lead (Pb)
The main lead (Pb) emission sources are combustion in residential plants and
energy industries and transport. In earlier years combustion of leaded gasoline
was the major contributor to Pb emissions to air but the shift toward use
of unleaded gasoline for transport have decreased the Pb emission from
transport by 93 %. In the non-industrial combustion sector the dominant
source is wood combustion in residential plants. The trend in the Pb emission
from non-industrial combustion from 1990 to 2010 is almost constant.
This is due to a decrease in emission caused by the shift towards unleaded
gasoline, as this sector includes other mobile sources in household, gardening,
agriculture, forestry, fishing and military. This is counteracted by an increase
in the emission from residential plants. The decreasing emission from
Energy industries (97 % from 1990 to 2010) is caused by the deceasing coal
combustion.
