In this chapter we identify the state-of-the-science regarding selenium (Se) bioaccumulation and trophic transfer. We discuss Se bioaccumulation and how its unique attributes tie bioaccumulation to toxicity. We identify biodynamic modeling as a promising approach that can provide a unied view of the processes contributing to bioaccumulation and illustrate how this kinetic modeling can be used and improved. We also discuss the most important uncertainties that need to be addressed if we are to better understand and model Se bioaccumulation.
