Development of a risk assessment system for soil contamination and the application to the social system

In developing risk assessment technology for soil contamination, it is essential to carry out a wide range of fundamental research and to synthesize the results into a single system. We have carried out an integrated research project for a comprehensive risk assessment system; this project includes fundamental knowledge, database formulation, commercialization of technology, and the introduction of the research results to a social system. In this paper, we present a scenario in Synthesiology, the integration of each part of the research results, and discuss the spiral processes involved in the implementation of risk assessment.
