Characterization of heavy metals in ashes from mixed refuse
1994
Hayashi, H. (Nagano-ken. Research Inst. for Health and Pollution (Japan)) | Nomura, Y. | Itoh, S. | Maruyama, M.
In order to ascertain the characterization of heavy metals in ashes from mixed refuse, the composition of those carried in A, B and C incineration facilities in Nagano prefecture was classified into 6 kinds of wastes and the amount of heavy metals, namely Cd, Pb, Cu, Zn, Ni, Mn and Fe, contained in residual ashes were studied. The different pattern of the waste composition found in B facility showed indirectly the special system of the waste treatment at the region. As compared with others, the concentration of Cd, Pb, Cu, Zn and Ni in ashes from plastics waste tended to high. The contributions of each combustible component against the total amounts of each heavy metal derived from mixed refuse were also shown.
