As the use and production of metal oxide nanoparticles (NPs) continues to rise, the potential for significant environmental contamination becomes more likely. Despite recent investigation into the environmental consequences of NP contamination, the effects of long-term exposure on organisms have largely been overlooked. In this experiment trophic transfer of CeO2 NPs from phytoplankton to a marine mussel, Mytilus galloprovincialis, was simulated by feeding contaminated phytoplankton to M. galloprovincialis. Accumulation and effects on clearance rate as a function of NP concentration were measured for five weeks. Additionally, NP sequestration behavior in M. galloprovincialis was compared for direct exposure to free CeO2 NPs and indirect exposure via contaminated phytoplankton.
