The Norwegian Environmental Agency took the initiative to and has been the project leader for this report. It was funded by the Nordic Council of Ministers, Nordic Working Group for Chemicals, Environment, and Health. At the time of initiating this project, other projects related to alpha-chloralose (AC) poisoning was ongoing both at the Swedish University Animal Hospital, the Swedish National Veterinary Institute and the Norwegian Veterinary Institute (2, 5,6).
