Outline of Final Research Achievements

The uneasiness of the health risk to the soil contaminated site becomes the big social problem. Particularly, there is not enough knowledge about the soil contaminants exposure route by way of a vapor phase.
In this study, human health risk through vapor-phase route from the contaminated soil was investigated, by considering with (1)volatilization from soil and (2)absorption and concentration to food and water. Moreover, possibility of the soil contamination was evaluated, by considering with (3)deposition and to the soil from vapor phase. In the industrial establishment which exhausted 100 kg/year or more to the atmosphere, it is suggested that the soil contamination is worsened by deposition without being known. New management method of the soil contamination that considered the exposure route by way of a vapor phase was suggested.
