RESUMEN
Various pollutants keep threatening the environmental status of the Mediterranean Sea, while the Marine Strategy Framework Directive requires that Good Environmental Status needs to be achieved in European Seas by 2020. Previous reviews already established that the ambition levels of national Programmes of Measures (PoMs) are low. This study focuses on the analyses of the levels of coherence and coordination of the proposed PoMs in the Mediterranean, concentrating on nutrient, contaminant, and marine litter pollution, as well as the introduction of non-indigenous species. Coherence and pollinator analyses of the proposed measures of Mediterranean EU Member States (MS) were performed. The results demonstrate that while the current coordination between MS is almost non-existent, several measures are already addressing the same pressures in similar ways and could be easily coordinated on transnational level. Increased coordination and coherence of PoMs in the Mediterranean are vital for achieving good environmental status in future years.

The aim of this work is to assess trace metal pollution status (Cd, Cu, Ni, Pb, Zn) in the waters of Saronikos Gulf, Greece, in line with the WFD and MSFD European Directives, based on data collected over a decade (2000-2010). Dissolved metal background levels are estimated for the first time for Greek marine waters and the upper limits are: Cd: 0.574 nmol L(-1); Cu: 8.26 nmol L(-1); Ni: 7.94 nmol L(-1); Pb: 2.60 nmol L(-1); Zn: 115 nmol L(-1). The variability of dissolved and particulate metals reflected the presence of several point sources and revealed the importance of natural mechanisms acting as non-point sources. The status of Saronikos Gulf is classified as 'High' for most metals studied. An exception to this is the enclosed Elefsis Bay where Cu, Ni and Zn concentrations are found above background. Our work will assist the implementation of WFD and MSFD directives in Greece.
