Description of key information

The key value for chemical safety assessment is taken from two experimental results, which confirm: LC50 > 100 mg/L (Bayer AG, 1984) and LC50 = 100 mg/L (ICI Brixham Laboratory, 1986). 

Key value for chemical safety assessment

LC50 for freshwater fish:
100 mg/L

Additional information

An acute fish toxicity test was performed according to the National procedure recommendation F.1.1., Federal Environmental Agency (Bayer AG, 1984). Brachydanio rerio was used as test species and the exposure time was 96 hours, giving a value LC50 > 100 mg/L. This result is confirmed by an experimental result performed by ICI Brixham Laboratory (1986) using Salmo gairdneri. In this case a LC50 (96h) of 100 mg/L is reported. Regarding these results, N-Methylethanolamine is not expected to be acutely harmful to fish.
