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 (0.04 mg/L). Therefore, bioavailability to aquatic organisms is strongly limited.

- All available tests (acute and chronic) for the test substance markedly show that toxic effects only occur far beyond the limit of water solubility.

  • Danio rerio LC50(96h) > 100 mg/L (WAF, nominal concentration)
  • Daphnia magna EC50(24h) > 100 mg/L (WAF, nominal concentration)
  • Daphnia magna EC10 (21 d) > 10 mg/L (WAF, nominal concentration)
  • Scenedesmus subspicatus EC50(72h) > 100 mg/L (WAF, nominal concentration)

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