Risk assessment of environmental chemicals

This article is a summary from eleven important symposia. In these meetings, critical facts were discussed which are the necessary basis for the important legislation about toxic substances in Europe, in the U.S.A. and in Japan. This review article should also be of some help to the readers of “Chemosphere” for direct contacts with the experts mentioned. It is therefore an informative and coordinative survey, in which chemical and ecotoxicological details are largely omited.
