抄録

The effect of extraction conditions (S/L and pH) on the toxicity evaluation of a municipal waste incinerator's (MWI) fly ash was examined by quantitative analysis and the Daphnia acute toxicity test.<BR>Regarding S/L, the toxicity of MWI fly ash per unit amount of fly ash, which was determined with the leachate prepared with S/L=1 w/v%, was larger than that which was determined with the leachate prepared with 10 w/v%.<BR>Regarding pH, the leachate prepared with pH=4 showed higher toxicity than that prepared with pH=7 or 12. The leaching condition with pH=12, however, was considered preferable in order to evaluate the release of lead, because the release of lead under this pH condition was higher than that of other pH conditions.<BR>Considering the relationship of pH dependency to the toxicity of leachate, the major toxic constituent in the leachate prepared with pH=4 was copper, and that prepared with pH=12 was lead.
