During the last decade, Health Impact Assessment (HIA) has been discussed worldwide as being an important tool for the development of healthy public policy. HIA has been advanced as a means of bringing potential health impacts to the attention of policy makers, particularly in sectors where health impacts may not otherwise be considered. HIA, a systematic assessment of potential health impacts of proposed public polices, programs, and projects, offers a means to advance population health by bringing public health research to bear on questions of public policy. In Korea, health-related items under current EIA (Environmental Impact Assessment) system can only be found in the categories of hygiene and public health. However, environment and public health are not adequately connected and also health is underestimated even though health is an important objective component for the implementation of Environmental Assessments (EA). As a result, health is not well integrated within criteria for investigating the impacts on environment. This study examines linkages for HIA from the related and relatively well-developed field of Prior Environmental Review System (PERS) which is similar to SEA and EIA in Korea.
