Abstract:

LONG TERM GOALS. Our long-term research goal is to determine the mechanisms and factors that regulate the uptake and accumulation of pollutant metals by phytoplankton and other particles in estuaries and the effect of this accumulation on the removal and biogeochemical cycling of metals. OBJECTIVES. In conjunction with John Donat and David Burdige at Old Dominion University, we are studying the influence of metal speciation and metalmetal interactions on the particulate cycling and removal of pollutant metals Zn and Cd in the Elizabeth River and Hampton Roads Estuaries, home of the Navy s Atlantic Fleet. We are especially interested in the role of metal uptake by plankton as well as in our ability of to predict removal of metals from algal uptake models. These models will be based on field data for free ion concentrations of controlling metals Zn, Cd, Cu, and Mn and laboratory data on algal uptake as functions of free ionic concentrations of these metals.
