100 mg/L

Additional information

The short-term toxicity of Benzylamine to Daphnia was assessed in one investigation which was conducted in compliance with OECD guideline 202 and, in addition, one publication regarding this endpoint from handbooks is available. The guideline compliant study is considered most reliable regarding toxicity of benzylamine to daphnids, whereas the publication is considered less reliable, due to lack of detailed method descriptions. In the study performed in accordance with the Method C.2 ‘Acute toxicity for Daphnia’ (2008) which is equivalent to OECD 202, the Daphnia were exposed to a range of concentrations (12.5 - 100 mg/L) of Benzylamine. Observations were made on the swimming ability and the immobilisation rate and the EC50 values were determined at >100 mg/L after 24 and 48 hours, respectively.

From the publicly available literature, the toxicity threshold for Benzylamine was stated to be 60 mg/L for Daphnia magna, but no information on the concentration ranges tested is provided.
