This report provides an overview of the substances, matrices and threshold values that Member States intend to use for the assessment of the Descriptor 8 in the 2018 MSFD reporting cycle.
 
This compilation helps evaluate existing gaps as well as differences between Member States and so identify issues to be addressed to achieve consistency with the new MSFD Commission Decision (EU 2017/848). This work is part of a process to help regulators to assess relevant contaminants in their jurisdictional area, thus aiming at EU national authorities but also at Regional Sea Conventions in the shared marine regions.
