The toxicity of benzocaine (ethyl 4-aminobenzoate; 98%) to eleven freshwater fishes was evaluated under various physical and chemical conditions. Tests conducted at three water temperatures, four hardnesses, and three pH's showed that none of these variables influenced toxicity. The higher temperatures tested did not increase the rate of toxicosis. Users of benzocaine should be cautioned that overdoses may lead to undue stress or mortality in exposed fish. Comparison benzocaine concentrations by high performance liquid chromatography at 0 and 96 hours showed no degradation of the compound during the exposure period.

Because concerns have been expressed about the effects of irrigating truck-garden crops with water from a stream treated with the lampricide 3-trifluoromethyl-4-nitrophenol (TFM), I conducted studies on the effects of TFM on young plants of common vegetables and fruits. Plants established in horticultural flats were irrigated for 12 h with water containing 10 mg/L of TFM and later compared with plants irrigated for a similar period with untreated water. Lettuce, radish, sweet corn, and potato plants were virtually unaffected. Green bean and tomato plants developed brown or dead spots on many leaves but growth rates and survival were not affected. Cucumber and cantaloupe plants were severely damaged; some were killed and about 40% of the leaves on surviving plants were dead or dying. Two weeks after treatment, the mean weight of surviving treated cantaloupe plants was significantly less than that of control plants.
