The National Institute of Technology and Evaluation (NITE) conducted a Web-based survey on citizens' awareness of chemical risk from the PRTR system. Citizens usually associate the word “chemical” with chemicals in food, their main interest with regard to chemical substances. They did not show much interest in publicized data on chemical substances based on the PRTR system. Citizens rarely participate voluntarily in risk communication sessions, and when they do, management of chemical substances may be regarded as outside their purview.
