Description of key information

Additional information

No toxic effects occur in the range of water solubility.

- The test substance exhibits a very low water solubility (0.002 mg/L at 20°C). Therefore, bioavailability to aquatic organisms is strongly limited.

- All available tests for the test substance markedly show that toxic effects only occur far above the limit of water solubility.

  • Danio rerio LC50(96h) > 100 mg/L
  • Daphnia magna EC50(48h) at a nominal concentration of 100 mg/L WAF (water accomodated fraction) > 100 mg/L
  • Scenedesmus subspicatus EC50(72h) > 100 mg/L
  • Daphnia magna NOEC >= 10 mg/L (NOEC = WAF of a loading rate of 10 mg/L; OECD 211)

- Activated sludge was not inhibited by the test substance: IC50 > 100 mg/L.
