Abstract: Disasters and accidents involving the proliferation of chemical pollutants cause serious problems for the environment and human health. For a disaster and emergency response, Ministry of the Environment of Japan has launched a study project on chemical risk assessment and management system. The aim of this project is to systematically investigate comprehensive monitoring methods of chemicals, dispersion prediction models, and risk assessment and management system under nonstationary circumstances and to develop information infrastructures involving these achievements. Several statistical issues on chemical analysis, anomaly detection, spatiotemporal modeling, exposure assessments, and health risk evaluation are arising for the realization of this system. We briefly introduce the overview of the study project, and as an example of achievements, demonstrate a software tool for exposure assessments of air pollutants via spatial interpolation methods using limited available data of pollutant concentrations immediately after accidents.
