6. 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 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 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.
