While this document is addressed to the Mediterranean Action Plan for further development of its Draft Protocol for the Protection of the Mediterranean Sea Against Pollution from Land-Based Sources, it could be addressed equally well to any of the other international conventions which deal with the prevention of chemical pollution of the seas.
