Abstract

Initial Risk assessments using physicochemical properties and acute toxicity are conducted to provide information for managers to decide the potential adverse effects and played as a tool for decision-making in development of new substances. In this study, we built initial risk assessment framework and carried out human and ecology initial risk assessment for three different pesticides of captan, glyphosate, and paraquat dichloride to confirm our framework. Two water estimation models of GENEEC (GENeric Estimated Environmental Concentration) and FOCUS (FOrum for the Co-ordination of pesticide models and their USe) were employed for pesticides exposure assessment. Application for paraquat dichloride and glyphosate uses shows very low human and ecology risk. On the other hand, high acute ecological risk was observed from the application for captan. These results showed good agreements with the U.S. EPA RED (Reregistration Eligibility Decision) reports verifying the framework of this study.

초기위해성평가는 신물질 개발시 급성자료와 물리화학적 특성자료를 이용하여 위해성평가를 수행하고 정책결정자들에게 위해성에 관한 정보를 제공하여 의사결정 수단으로 활용되고 있다. 본 연구에서는 초기위해성평가 체계의 틀을 구축하고 구축된 위해성평가 체계를 검증하기 위하여 captan, glyphosate, paraquat dichloride의 세 가지 농약을 대상물질로 하여 인체 및 생태의 초기위해성을 평가하였다. 이때 두 종류의 수계 예측 모형인 GENEEC (GENeric Estimated Environmental Concentration)과 FOCUS (FOrum for the Co-ordination of pesticide models and their USe)가 농약의 노출평가를 위하여 사용되었으며 glyphosate와 paraquat dichloride는 인체 및 생태에 위해성이 낮은 것으로 나타났으나 captan의 어류 위해성은 급성독성이 높은 것으로 나타났다. 이 결과는 U.S. EPA RED (Reregistration Eligibility Decision) 결과와 유사한 경향성을 보여 본 연구체계의 신뢰성을 검증할 수 있었다.
