AB Temporal monitoring of pollutants in aquaticsystems impacted by human activities is mandatory for a correctassessment on their environmental impact and later management.The aim of this work was to study the suitability of using siliconerubber passive samplers and caged organisms (Ruditapesphilippinarum), simultaneously, to examine the spatial andtemporal variability of priority and emerging contaminants in acoastal environment (Cadiz Bay, SW Spain) over the course of anentire year. Seasonal trends were observed for some classes ofcompounds, such as UV filters and fragrances, and attributed tofluctuations in their sources and changes in the hydrodynamicconditions, respectively. Up to 42 out of 48 (in seawater) and 27out of 37 (in biota) target analytes were detected, the highest concentrations being observed for synthetic fragrances and UV filtersin both biota (136.9−159 ng g−1) and the dissolved phase (3322.2−265.7 ng L−1). Conversely, spatiotemporal differences in theconcentrations of target contaminants in clam tissues were minimal. Higher field bioaccumulation factors (log BAF > 5) were foundfor priority substances. Overall, silicone rubber passive samplers proved to be more sensitive than sentinel organisms for monitoringspatiotemporal changes in the dissolved aqueous concentrations of contaminants, whereas the latter allowed for a more realisticevaluation of the potential uptake and bioaccumulation of each compound.
