都市廃棄物焼却炉より放出される浮遊粒子の元素組成

抄録

Suspended particles released from refuse incinerators were subjected to multielement analysis by means of instrumental neutron activation method and energy dispersive X-ray fluorescence spectrometry. The analytical results were compared with the elemental concentrations observed in the urban atmosphere, and the contribution of the refuse incineration to the urban atmosphere was roughly estimated. Greenberg et al. pointed out on the basis of their study on Washington, D.C. incinerators that the refuse incineration can account for major portions of the Zn, Cd and Sb observed on urban aerosols. According to our results, the contribution of the refuse incineration to the urban atmosphere for Zn, Cd and Sb is not negligible, but not so serious as in U.S.A. big cities. In big cities in Japan there must be other more important sources of these elements.
