The Role of Risk in Chemical Substitution Decisions. 1994
TURI Methods and Policy Report No. 8. Chemical substitution is a growing method of pollution prevention and toxics use reduction (TUR). Although a good deal of effort has gone into developing protocols for identifying potential substitutes, much less attention has been given to explicit identification and weighing of the health and environmental risks of alternative chemicals. This project focuses on the use of the tools of risk analysis in chemical substitution decisions. First, the way in which companies currently make substitution decisions is characterized from interviews with selected firms. Then proposed methods for chemical substitution are evaluated with a particular attention to role of risk in the schemes. Finally, a logic tree-based framework for evaluating the risks of alternative chemicals is proposed and discussed.
