Horn Point Laboratory, University of Maryland Center for Environmental Science

Co-Principal Investigator:

Deborah L. Penry, Donald P. Weston, University of California, Berkeley



The objectives of the proposed research are to determine how the partitioning of toxic substances among dissolved and particulate phases affects bioaccumulation by a benthic suspension feeder, and how quantification of this phase-dependent bioavailability could be applied in environmental risk assessment. We will establish the role that ingestion of organic and inorganic particulate matter plays in toxicant uptake by oysters.
