Abstract |
This report describes the development of a process for the environmental hazard assessment of substances, including principles and practical approaches. The assessment of whether a substance presents a hazard to environmental organisms is based on a comparison of the predicted environmental concentration (PEC) with the predicted no effect concentration (PNEC) to organisms in ecosystems. In this approach, the estimation of PEC values is based on exposure model calculations and PNEC values on toxicological data. It was demonstrated that, for the limited number of substances tested and using PNEC values for aquatic organisms only, the proposed approach represents a workable system for the aquatic environment. |
