Abstract

Ash samples were collected from site of open-air incineration and fire concerning Hanshin Great Earthquake which occurred in western Japan in the early morning of 17 January 1995. The average concentrations of total sum of PCDDs, PCDFs and Co-PCBs in ash collected from wood scrap of broken building fire site, house fire site, shoe-making factory fire site and electric appliances store fire site were 541, 442, 859 and 22,800 pgTEQ/g, respectively. Particularly, PCDFs among dioxin analogs generated remarkably at sites with a high TEQ. In addition, 79,000 t of ash was totally produced at five open-air incineration sites, and consequently the formation amount of PCDDs, PCDFs and Co-PCBs was estimated to be 70.7 gTEQ on the basis of these analytical data.
