235 都市ごみ焼却排ガス中の重金属に関する報告 Trace elements in flue gas from MSW incineration

This paper describes emissions and the dependence on particle size of trace elements, which are Hg, Cr, Ni, Mn, Cu, As, Se, Cd, Sb and Pb, in flue gas from MSW incineration (MSWI). We measured them at five MSWI plants which applied dry type of flue gas treatment included bag filter to reduce dioxins. And we got following results; (i) Cu, As, Se, Cd and Sb had a trend to be condensed under 1 micro meter. Mn was condensed under 1 micro meter and over 10 micro meter. Cr and Ni showed different trend in each plants. (ii) Dry type of flue gas treatment is good enough to remove trace elements and meets German regulations.
