In the Great Lakes Water Quality Initiative, the procedure to determine bioaccumulation factors (BAFs) accounts for bioavailability and food chain biomagnification. A summary of the derivation and uses of these methodologies will be made. The method for determining the freely dissolved (bioavailable) portion of the chemical in the ambient water is based upon a three compartment partitioning model which consists of the freely dissolved chemical, and chemical sorbed to dissolved and particulate organic carbon. The methodology accounting for food chain biomagnification in the prediction of BAFs uses food chain multipliers to adjust bioconcentration factors to BAFS. The food chain multipliers were developed using the food chain model of Gobas (1993) and Great Lakes data.
