Chemicals for Priority Action

The List of Chemicals for Priority Action in its current form was adopted in 2002. OSPAR focuses on the substances on Part A of the List and has prepared a background document on each.

The Background Documents assess the situation for the substance and conclude on what actions OSPAR should take to move towards the cessation target. They are reviewed periodically, resulting in review statements or revised Background Documents, depending on whether the new information available affects the risk evaluation and the recommended actions. Each of these chemicals also has a monitoring strategy detailing monitoring and progression towards the cessation target.

In 2004, OSPAR decided not to systematically run DYNAMEC for the selection and prioritisation of substances, because the evaluation of chemicals and their properties was sufficiently covered by EU legislation. In the work on substances of possible concern, OSPAR is relying on progress on the evaluation of substances under the REACH Regulation and on the prioritisation of substances under the Water Framework Directive.
