Summary: A thin-layer of clean sediment does not reduce DDT flux when bioturbation is occurring. In contrast, a thin layer of activated carbon is more effective at reducting DDT flux with bioturbation than not having bioturbation. A mass transfer and biodynamic model were used to simulate DDT flux and bioaccumulation.
