• The first step of the dioxin and furan emissions
  evaluation analyse of dioxins concentration in
  Baltic Thermal Power Plants in oil-shale and fly
  ash from electrostatic precipitators during the
  European Dioxin Project (1998). The result of
  measurements are presented in the table below.
• The second step Inventory of Dioxin and Furan
  Releases in Estonia which has been carried out
  at 2002 as part of a DANCEE (Danish Cooperation
  for the Environment in Eastern Europe) project
  Survey of anthropogenic sources of dioxins in
  the Baltic Region. The inventory results also
  are presenet in the table.
• The third step - Estonian-Danish cooperation
  project for investigation of dioxin emissions
  from Narva power plants. The current plan is to
  take 15 samples for determination dioxin content
  in atmospheric air. An overview of dioxin
  emissions from the power plant and one factory of
  oil shale oil production will be obtained by
  autumn, 2003.

Emission factors

• No measurements of dioxin and furan releases have
  been carried out in Estonia.
• The preliminary inventory is based on default
  emission factors from the UNEP Toolkit.

• Do you see a need for emission measurements at
  one or two important sources in your country?
• Yes,
• 1. Kunda-Nordic Cement - cement production
  factory
• 2. Viru Õlitööstus AS - shale oil production
  factory
• 3. Epler Lorenz AS - waste inseneration
  plant ?
• Do you have laboratories or institutes that could
  be contracted to perform such measurements?
• No
