Abstract
Published in March of 2003 for the first time, PRTR system are expected to encourage effective risk communication for chemical substances control by private companies and various levels of governments. It is important to make clear current situation on practical use of those data and risk communication. We conducted a questionnaire survey for local governments of prefectures and mega-cities, as well as private companies in Tokyo. The results suggested that both groups have not fully implemented substantial measures of risk communication yet, while promoting the dissemination of PRTR data. In addition, some of requests for another group are different each other.
