Additional information

This study determined the short-term toxicity of the test substance to aquatic invertebrates. Groups of 20 daphnids were exposed to concentrations of 0, 3.2, 5.6, 10, 18, 32, 56, and 100 mg/L of test substance. Daphnids were observed at 24 and 48 hrs after the start of the exposure for immobilization. The 48 -hr NOEC was 0.379 mg/l. The 48 -hr LOEC was 5.6 mg/L. The 48 -hr EC50 was 2.9 mg/L.
