Source: Indicators for the flow of mercury, cadmium and lead in the society, Bo Bergbäck, University of Kalmar, October 2004. Report made on behalf of KemI.

* To the reports' emission data for products data of emissions from combustion and industry are added, 0.8 tonnes 2004 according to the Swedish EPA.

The tabel shows the estimated quantaties of the metals lead, cadmium and mercury that have been used in Sweden. The time period for which the estimation has been done was chosen by how long the substance has had a not neglectable technical use in Sweden and for which it has been possible to find information sources to estimate this use.

All quantities are shown in tonnes to give a quick perception of the orders of magnitude.
