Comparative studies of macrophage function: Bivalve hemocyte chemiluminescence
Principal Investigator:
Robert S. AndersonStart/End Year:

Chesapeake Biological Laboratory, University of Maryland Center for Environmental ScienceTopic(s):
Description:
The main objective is to carry out comparative studies of the effects of metals and other chemicals on macrophage immune functions using mammalian and aquatic invertebrate animal models. This is part of a collaborative study to determine the potential for interspecies extrapolation of immunotoxicological data, in an attempt to develop models using alternative species for toxicity testing. Immunosuppressive effects of chemical exposure on bivalve blood cells (this proposal) will be compared to those produced by the same chemicals on rat alveolar macrophages (carried out by collaborators at the U.S. Army Chemical Research, Development and Engineering Center).

Exploring the Use of Benthic Microbial Fuel Cells to Remove Sulfide While Harvesting Energy from Oyster Aquaculture Biodeposits
Oyster aquaculture is a rapidly growing industry in Maryland’s Chesapeake waters which stimulates economic activity and may provide a host of ecosystem benefits. A potential concern associated with the intensification of the oyster aquaculture is the local production and accumulation of oyster biodeposits, which can lead to a porewater sulfide accumulation and declining bioturbation, symptoms of declining ecosystem function. Sulfide is naturally removed from the seafloor by the interactions between bioturbating infauna and sulfide oxidizing bacteria.
