Abstract
Decision making for risk management of brominated flame retardants, DecaBDE, was discussed. There seemed to be two type of gaps 1) the gap between the conclusion of risk assessment and consequence of RoHS Directive, 2) the one between the intention of RoHS Directive and behavior of manufactures responding to the directive. Although, in 2002, EU risk assessment of DecaBDE had not found any reason why DecaBDE had to be regulated, manufactures of electrical and electronics did not stop replacement of DecaBDE with alternative substances. The reason why this gap occurred was that risk assessment was set aside in the process of constructing RoHS Directive. At the same time, there was the second gap in the ideal of RoHS Directive and response of manufactures because there seemed to be unexpected risk and extra social cost.
