Abstract: Two methods to detoxify the lampricide 3-trifluoromethyl4-nitrophenol (TFM) were tested in the laboratory. Because the toxicity of TFM decreases as the pH of water increases, we also tested the application of sodium hydroxide (NaOH) to raise the pH of the water. Raising the pH by 1.5 units partly detoxified concentrations of TFM applied in lamprey control. Raising the pH of a small tributary of the Sturgeon River (Delta County, Michigan) detoxified the TFM enough downstream of the raised pH to reverse an ongoing major kill of nontarget fishes. |
