AB  - Impacts of secondary generated minerals on mineralogical and physical 
      immobilization of toxic elements were investigated for chelate-treated air 
      pollution control (APC) fly ash of a municipal solid waste incinerator. Scanning 
      electron microscope (SEM) observation showed that ettringite was generated after 
      the moistening treatment with/without chelate. Although ettringite can 
      incorporate toxic elements into its structure, elemental analysis by energy 
      dispersive X-ray could not find concentrated points of toxic elements in 
      ettringite structure. This implies that mineralogical immobilization of toxic 
      element by the encapsulation to ettringite structure seems to be limited. 
      Physical immobilization was also investigated by SEM observation of the same APC 
      fly ash particles before and after the moistening treatment. The transfer of 
      soluble elements was inhibited only when insoluble minerals such as gypsum were 
      generated and covered the surface of fly ash particles. Neoformed insoluble 
      minerals prevented soluble elements from leaching and transfer. However, such 
      physical immobilization seems to be limited because insoluble mineral formation 
      with surface coverage was monitored only one time of more than 20 observations. 
      Although uncertainty owing to limited samples with limited observations should be 
      considered, this study concludes that mineralogical and physical immobilization 
      of toxic elements by secondary minerals is limited although secondary minerals 
      are always generated on the surface of APC fly ash particles during chelate 
      treatment.
