Ecotoxicological risk of trace element mobility in coastal semi-artificial depositional areas near the mouth of the River Rhine, the Netherlands

Artifical sand replenishments are globally used as innovative coastal protection measures. In these replenishments elevated pore water concentrations of trace elements are found. This study investigated possible ecotoxicological risks at two intertidal depositional sites, the Sand Engine (SE) as a recent innovative Dutch coastal management project, and a semi-artificial tidal flat (TF). Using the Sediment Quality Triad approach, we considered three major lines of evidence (LoE): geochemical characterization, toxicity characterization using bioassays with the estuarine amphipod Corophium voluta...
