Trace metal concentrations in oxidation ponds
- Oak Ridge National Lab., TN
Heavy metal concentrations of Cd, Cr, Cu, Ni, Pb, and Zn in the wastewater, sludge, and biotic components of the Oak Ridge National Laboratory oxidation ponds were examined to determine whether metals accumulated in tilapia. Results indicated that metal levels in the wastewater and biotic components are generally low and that the major metal reservoir is the sludge. Metals did not accumulate beyond established standards in the muscle or liver of tilapia grown in the oxidation ponds. This result may be partially due to the rapid growth rates of these fish (1-2 g fish/sup -1//day/sup -1/), with new tissue developing more rapidly than metals can accumulate. Another factor may be that the high concentrations of organic complexes in the ponds lower the availability of metals to the biota.
