Description of key information
A study according to OECD 202 was performed to assess the acute toxicity of Bornafix to Daphnia magna. Groups of twenty, 1st instar Daphnia (less than 24 hours old) were exposed for 48 hours to 9 concentrations of Bornafix dispersed in Elendt M7 Medium. The incidence of immobilisation was recorded for each test and control group at 24 hours and at 48 hours. All results are expressed in terms of measured concentration as measured concentrations ranged from 81 - 95 % of nominal at 0 hours and 64 - 93 % of nominal at 48 hours. The 48h-EC50 (immobilisation) was determined to be of 2.8 mg/L with 95% confidence limits of 2.4-3.2 mg/L.
