Key result
Duration:
21 d
Dose descriptor:
NOEC
Effect conc.:
0.17 mg/L
Nominal / measured:
estimated
Conc. based on:
test mat.
Basis for effect:
immobilisation
Remarks on result:
other: Neutral Organic SAR
Validity criteria fulfilled:
not specified
Conclusions:
On the basis of no effects observed in a freshwater system, the NOEC value for the substance is estimated to be 0.170 mg/l for aquatic invertebrate for 21 days of exposure duration.
Executive summary:

Based on the prediction done using ECOSAR version, the long term toxicity on aquatic invertebrate was predicted for test substance. On the basis of no effects observed in a freshwater system, the NOEC value for the substance is estimated to be 0.170 mg/l for aquatic invertebrate for 21 days of exposure duration. Thus, it can be concluded that the test chemical can be considered as toxic to aquatic invertebrate at environmentally relevant concentrations and can be classified as aquatic chronic 2 as per the CLP classification criteria.
