The report gives a preliminary design and use of a soil/litter microcosm in which oxygen, temperature and humidity are kept constant and oxygen generation and carbon dioxide and heat evolution rates are monitored. Using four microcosms, one acting as a dead control, experiments were performed giving the following results: for 'identically' prepared and incubated microcosms, the coefficient of variation was as small as 3.8 percent for carbon dioxide evolution rate and as large as 9.9 percent for oxygen consumption rates. It was also found that an adjustment period of seven to ten days after microcosm preparation was necessary to approach relatively constant production rates. No organismal density changes due to cadmium were detected indicating the cadmium initially affects respiration, possibly by uncoupling respiratory phosphorylation, and that longer experiments might be necessary to detect population density changes.
