Estimates of community metabolism of simulated natural environments were derived by diel oxygen techniques over a period of nine months. During this time, toxicants were added to some of the pools. “Natural” environmental factors and toxicants that did not affect the communities (0.02 mg/liter p,p′ DDT; 0.1 mg/liter antimycin A; and 9.2 mg/ liter KMnO 4 ) usually resulted in simultaneous changes, up or down, in both community photosynthesis and respiration. Concentrations (mg/liter) of 0.9 and 2.6 formalin, 10.0 nigrosine black, 10.0 and 2.0 malachite green, 0.1 Diquat, and 0.5 and 5.0 CuSO 4 usually depressed community oxygen production and increased community respiration for periods of 1 to 20 weeks.
