Notes to table 3-7: *1: For several release sources, Finland has noted in their questionnaire response that the effects of present emission reduction systems are not taken into account, and that the release estimates may therefore be overestimated. *2: Sector specific waste deposits, is an "other controlled deposition" category, including for example special deposits for coal combustion residues in some countries and industry's own deposits (subject to authorities control). *3: The value for new inputs to the biosphere includes produced by-product mercury (of which most is exported). The number was derived here by the report author by combining several data from the Finnish questionnaire response. *4: The output figures from landfills/deposits to municipal waste and hazardous/medical waste describe the distribution on these two deposit types, and not mercury being physically moved from deposits to municipal or hazardous wastes. *5: Note that doubling counting can not be ruled out in overall sums for waste treatment - depends on national practices and how data were reported in questionnaire responses. Therefore, these sums were not included in the table.
