Sublethal Concentrations

The acute toxicity of larval lampricide (TFM: 3-trifluoromethyl-4-nitrophenol) to 35 species of benthic macroinvertebrates was determined in 96-h flow-through tests. The 96-h LC50 values range from 2.1 mg/liter for blackfly larvae, Simulium pugetense, to values in excess of 38.0 mg/liter for species with heavy exoskeletons: crayfish (Orconectes propinquus), dobsonfly larvae (Chauloides sp), and dragonfly naiads (Ophiogomphus sp.) Younger individuals of the clam (Ligumia sp.) and the mayfly nymph (Ephemerella cornuta) were 2 to 1.5 times more sensitive than larger individuals of the same species. Early emergence of adults and increased locomotor activity were observed among some organisms exposed to sublethal concentrations.
