21 d
Dose descriptor:
NOEC
Effect conc.:
0 mg/L
Nominal / measured:
estimated
Conc. based on:
test mat.
Basis for effect:
immobilisation
Validity criteria fulfilled:
not specified
Conclusions:
On the basis of no effects observed in a flow through freshwater system, the NOEC value for the substance was estimated to be 0.0000179 mg/l for aquatic invertebrate for 21 days of exposure duration.
Executive summary:

Based on the prediction done using ECOSAR version 1.1, the long term toxicity on aquatic invertebrate was predicted for test substance . On the basis of effects observed in a flow through freshwater system, the NOEC value for the test substance was estimated to be 0.0000179 mg/l for aquatic invertebrate for 21 days of exposure, Based on the NOEC value it can be concluded that the test chemical was considered as toxic to aquatic invertebrate at environmentally relevant concentrations and hence, considered to be classified in aquatic chronic category 1 as per the CLP classification criteria.
