摘要：Ecological risk assment (ERA) has been used to establish environmental quality standards or evaluate ecological risk in site- specific areas. The scope of ERA was expanded bused on regions,and the concept of regional- scale ecological risk assment was recently introduced in deweloped countries. In the present study, regional ERA approaches of relative risk model (RRM),contaminants in aquatic and trrestrial ecosystems (CATS) model,and procedure for ecological tired asessment of risks (PETAR) in advanced countries were extensively investigated. Regional ERA was compared with traditional ERA process. Stressors,receptor and response in traditional ERA were replaced with sources of stessors,habitats,and ecological impacts,respee- tively in regional ERA. This study introduces the concept and assment process of regional ERA. and provides a wide perspective how the relative ERA could be applied in Korean ecosystem.
