- test mat.
- Basis for effect:
- immobilisation
- Remarks on result:
- other: ECOSAR v1.11
- Validity criteria fulfilled:
- not specified
- Conclusions:
- On the basis of effects observed in a static freshwater system, the NOEC value for the substance is estimated to be 8.086 mg/l for aquatic invertebrate for 21 days of exposure duration.
- Executive summary:
The long term toxicity on aquatic invertebrate was predicted for test substance by using ECOSAR version 1.1. On the basis of effects observed in a static freshwater system, the NOEC value for the substance was estimated to be 8.086 mg/l for aquatic invertebrate for 21 days of exposure duration. By considering NOEC value, it is concluded that the test chemical can be considered as not toxic to aquatic invertebrate and can not be classified as per the CLP classification criteria.
