Description of key information

One read-across study is available. The 48-hour EC50 was calculated to be 0.0001 mg/L. The No Observed Effect Concentration established for this study was 0.000025 mg/L (Collins, 1992).

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
0 mg/L

Additional information

One read-across study is available which was conducted on Daphnia magna according to FDA Technical Assistance Document 4.08 under GLP (Collins, 1992).

The 48-hour EC50 (based on mean concentrations) was calculated by moving average angle analysis to be 0.1 μg/L (0.0001 mg/L). The No Observed Effect Concentration established for this study was 0.025 μg/L (0.000025 mg/L), the lowest mean measured concentration tested. See read-across justification document attached in section 13.
