Chemical accident is one of the main obstacles for industrial development of South Korea. In order to prevent future accidents, it is necessary to estimate and predict the potential location of a chemical accident. This study first conducted a chemical hazard assessment using spatial analysis of chemical factory and accident data in Korea and then evaluated the hazard by environmental receptor. It is found that the human habitation area was found to have the highest chemical accident hazard (72%), compared to biotic and abiotic areas. In addition, among five receptors (human, forests, farmland, water resource, livestock), humans face the greatest threats (99.7% are at risk), followed by water resource, farmland, livestock farms and forests with 67%, 52%, 46.6% and 42% respectively. This study can help the relevant stakeholders and decision-makers in effective prevention of chemical accident and environmental management.
