Comparison of Different Models for Environmental Hazard Classification of Chemicals. A Status Report from the Joint Nordic Project 'Guidelines for Environmental Hazard Classification of Chemicals'

摘要

This work covers two parts. The first part is the development of general criteria based on our general knowledge on the environmental fate, behavior and effects of chemical substances. The second part concerns the development of more specific criteria based on results from a limited number of specified tests about the intrinsic properties of chemical substances. One result of the Nordic co-operation was the formulation of specific criteria in a scheme described below as model N1. It was, however, felt that it was essential to demonstrate how the scheme works in practice; in an exercise, where at least a hundred chemical subtances were tested. This exercise should include not only the proposed scheme, but also a number of modifications of that scheme, together with other schemes developed elsewhere. This report is a status report on that exercise.
