Abstract
Soil risk assessment models were used to determine the goals of soil remediation and to establish the soil quality standards in developed countries. Recently, Korean Ministry of Environment prepared the guideline for soil risk assessment. Soil risk assessment model applicable to Korean situation will be needed in the near future. In this study, three models for soil risk assessment were extensively compared to suggest the fundamental components that required for the soil risk assessment in Korea. The models considered in this study were CalTOX in the United States, CLEA (Contaminated Land Exposure Assessment) in the United Kingdom, and CSOIL in the Netherlands. The major exposure routes and the intake estimation equations suitable for Korean situation were suggested. The exposure routes suggested were intake of the crops, underground water, indoor outdoor soil ingestion, dust inhalation and a volatile matter inhalation. The equations for intake estimation used in CalTOX and CSOIL seem to be applicable for the calculation of the human intake in Korea.

우리나라는 최근에 토양위해성평가 지침을 마련하였으며, 앞으로 토양위해성모델 개발에 대한 필요성이 대두되고 있다. 선진국에서는 자국 내 부지특성과 노출경로를 고려한 토양위해성평가 모델을 토양정책 전반에 활용하고 있다. 본 연구에서는 선진국에서 위해성평가에 이용되는 대표적인 오염토양 위해성평가 모델을 비교분석하였다. 연구대상이 된 모델은 미국, 영국, 네덜란드에서 사용하고 있는 CalTOX, CLEA, CSOIL로서, 노출경로, 토지이용도 그리고 노출량 산정식을 중심으로 비교분석하였다. 모델 검토시 우선적으로 비교 분석된 항목은 노출시나리오, 노출경로, 입력변수의 공통사항이며, 이러한 분석결과를 토대로 선진국의 토양위해성 모델들이 공통적으로 포함하고 있는 노출경로를 추출하여, 국내에 적용 가능한 토양 위해성평가 모델개발의 기초자료로 제안하였다. 인체노출량 산정식에서는 일반적으로 미국식 방법이 국내 상황에서 사용이 용이한 것으로 판단되며, 비산먼지나 휘발물질 흡입의 경우는 네덜란드식이 기본값이 제공되어 있으므로 사용하기가 편리할 것으로 판단된다.
