Technical report series: North Alabama water quality assessment: Volume 10, Concentrations of PCBs, DDTr, and selected metals in catfish from Wheeler and Pickwick Reservoirs
After finding polychlorinated biphenyl (PCB) levels above 2.0 ..mu..g/g in catfish from Wilson Reservoir in autumn 1984, the Tennessee Valley Authority decided to sample catfish from Wheeler Reservoir (upstream of Wilson) and Pickwick Reservoir (downstream of Wilson). These samples were collected in August and September 1985 and all had detectable levels of PCBs, some near or above 2.0 ..mu..g/g. Wheeler Reservoir catfish had highest levels in upstream reaches (up to 2.6 ..mu..g/g in one composite sample), decreasing progressively downstream (<0.5 ..mu..g/g in several composite samples). Pickwick Reservoir (downstream of Wilson) showed a similar distribution with highest PCBs levels (up to 2.3 ..mu..g/g) at the upstream location and levels decreasing in a downstream direction (lowest level 0.11 ..mu..g/g). These fish were also analyzed for DDTr (DDT and metabolites) and selected metals. In Wheeler Reservoir DDTr levels were higher in the upper reaches due to the known DDT contamination there. Levels were generally low in Pickwick Reservoir except at the uppermost location where one sample had 7.4 ..mu..g/g.
