Description of key information

After 48h a NEC of 3.7 mg/l and a EC50 of 7.3 mg/l were determined.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
7.3 mg/L

Additional information

Twenty daphnia magna each were exposted to norbornene in 6 concentrations ranging from nominally 2.2 to 100 mg/l in test according to OECD 202 resp. EU C.2. From the experiment after 48h an EC50 value of 7.3 mg/l and a NOEC of 3.7 mg/l could be determined. the concentrations are based on the geometrical mean of the concentrations determined before and after the tests in each treatment.
