註1：試驗方法為NEN7345, "Leaching characteristics of solid earthy and stony building and waste materials- Leaching tests- Determination of the leaching of inorganic components from buildings and monolithic waste materials by diffusion test"，以及CEN/TS 14405, "Characterization of waste - Leaching behaviour tests - Up-flow percolation test (under specified conditions)"。

註2：其他As、Cd、Cr、Co、Hg、Pb、Mo、Mi、Sb、Sn、Zn等11項重金屬皆有分析，惟溶出濃度低於偵測極限或累積溶出量小於環境背景係數，故並無百年環境釋入量。
