【 摘 要 】

The aim of the study was to collect data for better control of mercury emissions in Slovenia, especially from the point and spread sources of all categories. In the past years the Slovenian industry avoided the use of mercury as a raw material in the productionprocess to prevent the emissions and discharge of this hazardous substance. About 733 kg of Hg was imported with products, 620 kg Hg was produced with coal combustion and cement production, 920 kg was sold with products and around 200 kg was exported as waste in year 2001. Annually 1620 kg of Hg emission into environment is estimated, of this approximately 900 kg is deposited as waste, 630 kg escape in the air and 90 kg in water. The following sectors have been identified in Slovenia as the potential sources of mercury into environment: the thermal power plants, dental amalgams, products of electric industry (batteries, lamps, thermometers, manometers, barometers), chemicals, cement industry, incineration and waste treatment. A mercury flow diagram for Slovenia in theyear 2001 was established.
