White Oak Lake

Distribution of Pu and Other Actinides in Components of White Oak Lake... 

Research on the behavior of Pu and other actinides in aquatic ecosystems of Oak Ridge National Laboratory involves field studies at White Oak Lake, a 10.5-ha impoundment formed by Mahattan Project operations. This final settling basin has received releases from the Laboratory and associated facilities since 1944. Some of the key questions addressed are (a) the partitioning of Pu between the suspended particulate and soluble fractions in the water column, (b) the partitioning of Pu between the bed sediments and overlying water column, (c) the uptake of Pu by biota from these fractions, and (d) food chain transfers and trophic effect on Pu concentrations in biota of the system.

In a study of insect-plant relationships at Oak Ridge National Laboratory, Crossley (1963) utilized a field nuclear waste site containing Cs. Chrysomela knabi beetle larvae were collected on leaves from willow trees (Salix nigra) growing on White Oak Lake bed. This lake was formerly a low-level waste disposal site at the laboratory, and the sediments contained various radionuclides, including Cs. Consequently, the leaves of the willow tree contained Cs... 

Two papers concerning the use of a radionuclide technique in studying feeding rate of fish will be discussed, that of Kevem (1966) for yearling carp (Cyprinus carpio) collected from White Oak Lake, Oak Ridge National Laboratory, and that of Kolehmainen (1974) for bluegill (Lepomis macrochirus) from the same lake. The studies involved determination of the amount of Cs required to be ingested to maintain an equilibrium body burden in both species. The...
