Description of key information

48-h EC50 >816 mg/L mobility Daphnia magna, reliability 1

Key value for chemical safety assessment

Additional information

A 48-h EC50 value of >816 mg/l and NOEC of ≥816 mg/l (EU Method C.2 (Acute Toxicity for Daphnia) have been determined for the effects of the test substance on mobility of Daphnia magna based on nominal concentrations of the substance.

As the substance hydrolyses rapidly (half-life approximately 2.6 hours) to propysilanetriol, under ecotoxicity testing conditions the organisms are exposed predominantly to the hydrolysis product.
