Health risk assessments for the abandoned asbestos mine were usually performed with activity-based sampling (ABS) method, which was not a effective tool for indexing health risk on an exact small area of mine. A newly proposed potential index of health risk (PIHR) was applied with proper spatial determination of geographical information system (GIS) to assess quantitatively health risks. A new trial was applied to a certain abandoned mine in Boryong as follows: A high grade area of PIHR was estimated 7.8% of the whole area of the mine (about 27.3 ha). Based on US EPA IRIS (integrated risk information system) model considering lifetime excess cancer risk (LECR), the health risk assessment indicated that the high grade area increased from 3.0 ha through 12.9 ha to 19.5 ha with an increase of asbestos contents in soil from 0.36% (1E-04 level) through 0.1% (3E-05 level) to 0.04% (1E-05 level). These results can be effectively applied to determine reclamation area of the abandoned asbestos mine.

Dietary intake and oncogenic risk of 12 pesticides used in Korea whose oncogenic potency was known were assessed from published data. Dietary oncogenic risk (excess tumor incidence for a 70-year human life span) for Korean population was estimated to be $2.17{\times}10^{-3}$ on the basis of legal maximum residue limit, $4.33{\times}10^5$ on the basis of maximum practical residue level and $5.10{\times}10^{-6}$ on the basis of mean practical residue level of examined pesticides, all of which exceeded the negligible risk standard $1{\times}10^{-6}$ of US EPA. A systematic follow-up study on those oncogenic pesticides should be undertaken in order to mitigate the people's worry about the cancer risk by the abuse of pesticides in food production.
