    Abstract

    A need exists to devise systematic procedures to evaluate the hazard to aquatic organisms of new materials prior to their commercialization. Assessment of hazard implies decision making and risk taking. Now, more than ever before, companies must incorporate environmental safety considerations into that decision-making process of new product development.

    A tentative procedure is presented which utilizes environmental fate and aquatic organism toxicity data in the sequential phases of screening, predictive, confirmative, and monitoring studies to arrive at a decision either to continue the toxicity testing, terminate the project because of unacceptable risk, or cease testing because of an acceptable risk. Application of the procedure to a number of potential new products in the past few years has verified the utility of the approach.

    The procedure was also tested on three hypothetical materials that varied widely in their use, chemical, physical, and toxicological properties. This analysis demonstrated the flexibility of the system for aquatic hazard evaluation and decision making.
