| Resumo: |
Since 2008, projects supported by french government agencies were dedicated to improve the assessment of chemical contamination of water bodies defined by the Water Framework Directive (WFD, 2000/60/CE)(Munaron et al, 2012). Among these studies, the aim of PEPSLAG was to investigate the utility of passive samplers for sampling contaminants present at trace levels in coastal lagoons environments, and to realize a first assessment of the contamination on the French Mediterranean coastal lagoons. 23 transitional lagoons water-bodies were investigated along the French Mediterranean coast, using three kinds of passive samplers (DGT, POCIS and SBSE). 141 contaminants from various chemical families (trace metals, pesticides, pharmaceuticals, alkylphenols, PAHs, PCBs…) were searched and their concentrations compared to Environmental Quality Standard (EQS) that exist. With passive sampling techniques used, concentrations of many contaminants have been detected and measured in their "dissolved" forms. The study showed the operational assets of these systems, as low quantification limits required by the WFD reached and ensure measurement of metals and organic contaminants at trace levels, which are generally difficult to quantify with classical methods, especially in marine waters. In this study, many usual contaminants that have an EQS did not overstep it except some insecticides and trace metals. In spite of this, many water bodies have been considered in a bad chemical quality according to WFD. These passive samplers represent a sensitive and promising tool for use in marine and coastal monitoring under the EU WFD and the future EU Marine Strategy Framework Directive. Indeed, information is needed about marine contamination and passive samplers could clearly help to better characterize the real exposure of marine organisms to complex mixtures of contaminants present at low concentrations.
