Development and Validation of Bioaccumulation Models for Small Mammals

ACKNOWLEDGMENTS The authors would like to thank Ron Mellot and Rob Pastorok of PTI Environmental Services for their assistance in providing unpublished validation data. In addition, this report has benefitted from the review and comments of Sylvia Talmage and Chris Welsh. v PREFACE While considerable data are available concerning chemical concentrations in small mammal tissues in relation to environmental contamination, models relating soil concentrations to whole-body concentrations have not been developed. The purpose of this document, then, was to develop a database of soil and whole-body small mammal concentrations for 9 inorganic chemicals, based on data from 22 studies from 4 countries and 9 states. This information will be used to evaluate risks to predatory wildlife on the Oak Ridge Reservation. Plant and earthworm data and models are presented in companion reports ES/ER/TM-218 and ES/ER/TM-220, respectively.
