Valorisation des données de la surveillance DCE - Synthèse des données des suivis chimiques «Biote » (2008-2010), « Sédiment » (2008) et « Eau » (2009) - Masses d’eau côtières et de transition du district Adour-Garonne

This report presents recent data on chemical contaminants in coastal and transition water bodies of Adour-Garonne district, acquired as part of the WFD (water measurements in 2009) and network ROCCH (measures in sediments in 1999 and 2008 and in shellfish each year between 2008 and 2010). It should be noted that only environmental quality standards exist for water, and in the absence of sediment and biota EQS, it is not possible to use these data to determine the chemical quality of water bodies. However, when other types of reference values are available (produced by OSPAR for example), they are used to argue the status of water bodies in support of the data obtained on the water under the control WFD monitoring.
