Abstract

Health impact assessment is implemented within the Environmental impact assessment for the purpose of minimizing health damage by predicting the impact on human health following implementation of the development project. In health impact assessment, manual revision is required due to the lack of consistency in the method of estimating hazardous air pollutants emissions. This study estimated the emissions by calculating the emissions of hazardous air pollutants based on the actual industrial complex development cases and completed health impact assessments. As a result of risk assessment based on exposure concentration using CALPUFF model, the risk assessment results were different for each of the emission estimation methods, and manual improvement on the emission estimation method is needed.

건강영향평가는 개발사업 시행에 따른 사람의 건강에 미치는 영향을 예측하여 건강피해를 최소화하기 위한 목적으로 환경영향평가 내에서 시행되고 있다. 하지만 건강영향평가 시 유해대기오염물질 배출량 산정방법에 대한 일관성 부족으로 건강영향평가 매뉴얼 개선이 필요하나, 아직 개정은 되지 않고 있다. 본 연구는 실제 산업단지 개발 사례 및 기 수행된 건강영향평가를 중심으로 유해대기오염물질 배출량 산정 시 매뉴얼에 제시된 원단위 산정 방법을 다르게 적용한 4가지 사례를 선정하여 각각 배출량을 산정하였다. 각 산정된 배출량을 토대로 CALPUFF 모델을 이용한 확산농도 예측 후, 노출농도를 기준으로 위해성 평가를 시행하였다. 위해성 평가 결과, 배출량 산정 방법별 위해도 수준의 차이가 비교적 크게 나타남에 따라, 배출량 산정시 원단위 적용에 대한 매뉴얼 개선이 필요한 것으로 검토되었다. 또한 배출량 산정 시 근거자료 활용에 대한 일관성, 건강영향평가에 최적화된 배출계수 개발, 현황 조사에 대한 신뢰성 향상이 필요할 것으로 판단된다.
