リスク評価とリスク管理の位置づけを再構成する解決志向リスク評価

抄録

This article introduces a concept of “solution-focused risk assessment (SFRA)” to propose a specific vision of collaboration between risk assessors and risk managers. SFRA can evaluate the risk reduction outcome and cost-effectiveness of possible risk management options (solutions). The opening question should not be “How bad is the problem?” but “How good are the solutions we might apply?”, because we can think about solutions before we fully understand the problem (risk). The needs of SFRA were discussed by taking risk management deficits regarding radioactive substances in food as an example. Then, the pros and cons of SFRA were discussed. The notable benefit of SFRA is giving stakeholders opportunities to understand the possible solutions. After that, the history of functional separation of risk assessment and management was reviewed. Finally, some specific examples of application of solution-focused risk assessment were given from dichloromethane as paint remover, acrylamide in food, mercury in fish, and ecological risk by pesticide use.
