  <dc:description>&lt;p class="chapter-para"&gt;Exposure of fourth instar larvae of Chironomus tentans to 2.0‐8.0 mg/liter of TFM (3‐trifluormethyl‐4‐nitrophenol) for 6 hr at 22 ± 0.5 C in soft water resulted in a significantly increased rate of larval oxygen consumption compared to that of control larvae, as measured with the Warburg respirometer. Maximum stimulation of oxygen consumption occurred with 8.0 mg/liter of TFM, and 1.0 mg/liter of TFM had no measurable effect on basal respiration. When hardness of exposure water was progressively increased, the effect of TFM on oxygen consumption was diminished.&lt;/p&gt;&lt;p class="chapter-para"&gt;Bayer 73 (5,2′‐dichloro‐4′‐nitrosalicylanilide) stimulated oxygen consumption at 0.75 and 1.0 mg/liter, had no significant effect at concentrations less that 0.75 mg/liter, and inhibited oxygen consumption at concentrations of 1.20 mg/liter or greater.&lt;/p&gt;&lt;p class="chapter-para"&gt;Mixtures of TFM and Bayer 73, in the ratio of 98:2, had no greater effect on oxygen consumption than TFM alone.&lt;/p&gt;</dc:description>
