Abstract |
Laboratory aquatic microcosms were established using natural pond sediment and the organisms contained therein. After a 30-day development time, microcosms were exposed on a flow-through basis to six concentrations of copper with six replicates of each concentration. Measures of energy fixation, material cycling, and biological structure were measured periodically over a 32-wk period. Exposure to copper at 9.3 microgram/l and higher resulted in a change in the structure and function of the test systems while 4.0 microgram/l did not cause an effect relative to controls. |
