Accumulation of cadmium, chromium, and lead by bluegill sunfish (Lepomis macrochirus Rafinesque) under temperature and oxygen stress. Final report
Technical Report

OSTI ID:6721984
The effects of acclimation temperature (7, 18, 29 C) and dissolved oxygen concentrations (4.5, 6.5, 8.5 mg/l) were tested upon accumulation of various heavy metals by bluegill sunfish (Lepomis macrochirus Rafinesque) Temperature acclimated fishes were held at various dissolved oxygen levels and exposed to 0.5 ..mu..g/ml of cadmium, chromium, and lead for 7 days. Heavy metal content of various internal tissues and organs was determined as well as levels of 14 additional elements. Accumulation results were analyzed by two-way analysis of variance. Accumulation of chromium and lead in gill tissue appears to be related to dissolved oxygen levels, while accumulations of cadmium, chromium and lead in all other tissues are explained by acclimation temperature. Tissue concentrtrations of additional elements are also reported.
