Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
