Generation mechanism of 1,4-dioxane in the exhaust gas from an industrial waste incineration facility

抄録

The mean concentration of 1,4-dioxane in the atmosphere is 0.029 µg/m³. This value is higher than those of water and food. At the industrial waste incineration facility targeted in this study, 1,4-dioxane was generated when the exhaust gas was passed through a dry process neutralizing apparatus with a lime coated bag filter. It is conjectured that the 1,4-dioxane is generated from the lime on the bag filter. Thus, the 1,4-dioxane generation mechanism was investigated via a simulation experiment where the dry process neutralizing apparatus was replicated.
