Description of key information

no EC50 could  be established up to the limit of water solubility.

Key value for chemical safety assessment

Fresh water fish

Fresh water fish
Effect concentration:
7.3 mg/L

Additional information

In a static fish test on guppy no EC50 could be determined up to 40 mg/l Norbornene, which was the highest concentration tested due to the limited water solubiltity. (VEB Leuna, 1979)

In a limit test meeting OECD 203/EU C1 standard, no mortalities could be observed at 7.3 mg/l. (Muckle, 2010), confirming the realier results. NOEC > 7.3 mg/l; LC50>7.3 mg/l

Due to software limitations, a LC50 value of 7.3 mg/l will entered as key value for CSA.
