Description of key information

The EC50 value based on mobility was determined to be 7.29 mg/L in a 48 hours test on daphnia. 

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
7.29 mg/L

Additional information

A study was conducted on daphnia to assess the short-term toxicity of the test substance to aquatic invertebrates. As a result, the EC50 value based on mobility was determined to be 7.29 mg/L.

In a publication (Smith et al. 1988) several substances were tested for their toxicity to Daphnia pulex. The 48 h EC50 of 1-Methylpyrrolidine was determined to be 2.08 mg/L (nominal), based on mobility. In the second publication (Passino & Smith, 1987), a similar study is described revealing an 48 hour EC50 of 4.64 mg/L for the test substance tested with Daphnia pulex.
