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. Each of these chemicals also has a monitoring strategy detailing monitoring and progression towards the cessation target.

In 2004, OSPAR decided not to systematically select and prioritise substances, because the evaluation of chemicals and their properties was sufficiently covered by EU legislation.

OSPAR is undertaking a full review of the OSPAR List of Chemicals for Priority Action, to filter and rationalise it in light of the registration, evaluation and authorisation of chemicals (REACH) Regulation and on the prioritisation of substances under the Water Framework Directive.
