In Sweden there are no legislative regulations regarding mercury in fluegas emission from crematoria. The crematoria do not have treatment facilities to reduce mercury emissions, although they are the third highest emission source of mercury in Sweden. Included in this paper are the data on mercury emission during cremations with and without the addition of selenium for the reduction of mercury emission. Tests were carried out during 22 cremations. The use of selenium gave emission reductions of 80 to 85% in stack gases, and 20 to 50% in the emission peaks.
