The list of Priority Substances
The authorities have drawn up a priority list of hazardous chemicals, and set targets for when emissions of these substances should be substantially reduced or completely eliminated.
The Observation list
The Observation list includes substances that are particularly hazardous to health or the environment and are used so widely or in such amounts that they may represent special problems at national level. It is not an exhaustive list of all such substances. The Observation list has not been evaluated since 2002.
The list of Dangerous Substances
Approximately 3500 substances are included in the Norwegian list of Dangerous Substances. This list is the Norwegian implementation of the Annex 1 to Directive 67/548/EEC on the approximation of the laws.
