Additional information

A study was conducted to determine the acute toxicity of the test substance, trichloro(N,N-dimethyloctylamine)boron, to Daphnia magna according to OECD Guideline 202 and EU Method C.2, in compliance with GLP. Twenty daphnids (4 replicates of 5 animals) were exposed to an aqueous solution of the test substance at nominal concentrations of 10, 18, 32, 56 and 100% v/v saturated solution for 48 hours at a temperature of approximately 20°C under static test conditions. Immobilization and any adverse reactions to exposure were recorded after 24 and 48 hours. Analysis of the test preparations at 0 hours showed measured test concentrations to range from 0.063 to 0.75 mg/L. There was no significant change in the measured concentrations at 48 hours and so the results are based on 0 hour measured test concentrations only. Under the study conditions, the nominal 48 h EC50 was determined to be 0.75 mg/L (Harlan, 2014).
