Uptake of dissolved and particle-associated toxicants by the eastern oyster

Principal Investigator: 

Roger I.E. Newell

Start/End Year: 

1991 to 1994

Institution: 

Horn Point Laboratory, University of Maryland Center for Environmental Science

Co-Principal investigator:

Topic(s): 

Description: 

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.
