1.9 mg/L
Nominal / measured:
estimated
Conc. based on:
not specified
Basis for effect:
not specified
Remarks on result:
other: Other details not known
Validity criteria fulfilled:
not specified
Conclusions:
On the basis of no effects observations on the Daphnia magna, the NOEC value for the substance was estimated to be 1.9 mg/l for aquatic invertebrate after 21 days of exposure duration.
Executive summary:

Based on the prediction done using ECOSAR, the long term toxicity on aquatic invertebrate Daphnia magna was predicted for test substance. Study conducted under the flow-through system. The NOEC value for the test substance is estimated to be1.9 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 non toxic to aquatic invertebrate at environmentally relevant concentrations.
