Biological Processes Affecting Bioaccumulation, Transfer, and Toxicity of Metal Contaminants in Estuarine Sediments

Abstract

The objectives of this research project were to 1) to characterize metal trophic transfer from sediments to intertidal food webs and determine food web structural variables that are sensitive to biological exposure and bioaccumulation in studies of reference vs. contaminated sites, 2) to understand processes regulating metal bioaccumulation in animals from contaminated sediments, to measure rates and routes of metal bioaccumulation in benthic animals, and to develop a predictive biokinetic model of metal bioaccumulation in benthic fauna representing different functional groups (deposit feeder, filter feeder, and omnivore/predator), and 3) to produce a set of robust genomic biomarkers that are predictive of the site-specific hazards posed by contaminated sediments.
