Substance flow analysis (SFA) is necessary for a proper environmental policy. Electricity and heat generation is main source of mercury emission to air in Poland (5.3 Mg annually). Remaining industrial sectors (4.3 Mg) and fuel combustion in residential sector and commercial plants (1.0 Mg) are next sources of this emission. Use of mercury-containing products (0.8 Mg) and dental practice and bodies cremation (0.3 Mg) are other sources of emission to air. From emitted load 11.7 Mg Hg majority (7.8 Mg) is deposited to soil and remaining flow is transported abroad. Due to E-PRTR data for 2014, mercury discharge to water was 1.86 Mg, mainly from large and medium industrial facilities (1.51 Mg) as well as rest from municipal waste water plants in large towns (0.36 Mg). Sewage sludge from waste water plants transferred to agriculture is source of mercury emission to soil (0.31 Mg). Mercury discharges to water and soil from dental amalgam in buried bodies (0.16 Mg) are other emission source. Significant flow of mercury to wastes is associated with use of mercury-containing products (6.6 Mg Hg in products launched to the market in year). Load of 1.7 Mg of mercury is transferred to municipal landfills, next 3.7 Mg is re-collected and stored safely. Next significant mercury flow in wastes (10.0 Mg/year) originate from use. Half of mercury flow (4.9 Mg) contained in dental amalgam is re-collected in dental clinics and stored safely. Load 2.9 Mg is transferred to infectious medical wastes, later incinerated in industrial plants and in majority (2.6 Mg) stored safely.
