According to the Water Framework Directive (WFD), (Directive 2000/60/EC) the Chemical Status of water bodies is assessed on the basis of the compliance for each priority substance of the measured concentration with Environmental Quality Standards (EQS). EQS marine water for lead (Pb), cadmium (Cd) and nickel (Ni) refers to the dissolved concentration. In aquatic environments, most chemical contaminants (metallic or organic) are present at trace levels, complicating the detection (and quantification) of contaminants by standardized analytical techniques. Beyond that, the low spatial and temporal representativeness of the results of spot sampling has been pointed out, therefore the use of integrative matrix, such as molluscs, or passive samplers is preferred to monitor the chemical contamination of water bodies. The use of passive samplers, enabling low disturbance in situ sampling of trace element species and providing time-averaged concentration of contaminants during the deployment time, appears as a more reliable approach for the environment chemical monitoring. The MONITOOL project focuses on the diffusive gradients in thin films (DGT) technique, which stands out as one of the most widely used passive sampler for metals. Despite the wide application of DGTs for in situ measurements of metal speciation in numerous scientific studies, the use of DGT results in a regulatory context for chemical status assessment is not considered as yet.

The MONITOOL project aims to provide a robust database of dissolved and labile metal concentrations in transitional and coastal waters for adapting existing Environmental Quality Standards (EQS; 0.45 µm-filtered) for passive sampling devices (EQSDGT), in order to evaluate the chemical status of marine waters under the WFD. 8 European partners and 6 associated partners are involved in MONITOOL project.
