The EC50 of 2-Norbornene was determined as EC50 >1000 mg/l

Key value for chemical safety assessment

EC50 for microorganisms:
1 000 mg/L

Additional information

measurement of toxicity to microorganisms using non-acclimaticed sludge from a domestic waste water treatment plant lead to an EC50 > 1000 mg/l. The study was conducted according to OECD 209 under GLP.

In a second, current study an EC50 of 27 mg/l (measured value) was determined. This study is currently only available as draft and several issues concerning the conduct of the study still neeed to be clarified. The study is currently not taken into consideration.
