Oxygen consumption of box mussel Septifer bilocularis L. (0.17-0.18 g d.w.) was monitored for one hour during exposure to diazinon and glyphosate pesticides. Depletion of disssolved oxygen was also monitored at 10 min intervals for 2 h. There were no significant differences (p0.05) between the control and the treatments at low concentrations. At concentrations of 0.6, 6, and 30 ppm diazinon, the oxygen consumption rates were [mean+-standard error (SE)] 193.46+-38.84, 239.77+-40.36, and 208.05+-38.57 ml O2/h/g respectively. In sublethal concentrations of 480, 720, and 960 ppm glyphosate, the rates were 195.26+-43.06, 252.28+-36.06, 225.43+-22.40 ml O2/h/g respectively (157.27+-34.10 ml O2/h/g in the control). Concentrations of 6 and 30 ppm diazinon, and 720 and 960 ppm glyphosate were required to show a statistically significant (p0.05) effect on the oxygen consumption. In low concentrations, both pesticides tended to increase oxygen consumption of the mussels, but oxygen consumption decreased if the concentrations increased.
