Description of key information

A 21-day NOEC value of ≥100 mg/L has been determined for the effects of the trichloro(ethyl)silane, CAS 115 -21 -9, on survival and reproduction of Daphnia magna when expressed in terms of nominal concentrations. When expressed in terms of mean measured total organic carbon concentration in the test medium the NOEC was ≥10 mg/L. It is likely that the test organisms were primarily exposed to the hydrolysis products of the substance.

Key value for chemical safety assessment

Additional information

No study of long-term toxicity to aquatic invertebrates is available for the registration substance. A reliable study with a suitable read-across substance (trichloro(ethyl)silane, CAS 115-21-9) is available. A 21-day NOEC value of ≥100 mg/L has been determined for the effects of the trichloro(ethyl)silane, CAS 115 -21 -9, on survival and reproduction of Daphnia magna when expressed in terms of nominal concentrations. When expressed in terms of mean measured total organic carbon concentration in the test medium the NOEC was ≥10 mg/L. It is likely that the test organisms were primarily exposed to the hydrolysis products of the substance.
