Different groups of hard coal consumers use various coal size fractions. Therefore, knowing the content of mercury in different coal size fraction one can predict the potential contribution of various coal users to the overall mercury emission in Poland. The article emphasized the potential contribution of mercury emission from residential coal burning to the overall mercury emission in Poland. The base for the discussion is the results of research on mercury content in Polish commercial coal products. All hard steam coal sizes (coal classes) were under consideration. The results confirmed that under Polish conditions the contribution of the residential coal burning is smaller than presented in different papers and inventories concerning global mercury emissions.
