Description of key information

The acute toxicity of Pyrrolidine to aquatic invertebrates was assessed according to OECD guideline No. 202 and GLP principles. Nominal concentrations were the following:
- Range-finding test: 0.1, 1.0, 10 and 100 mg/L
- Final test: 10, 18, 30, 56 and 100 mg/L
During the exposure period the measured concentration remained constant (98-101% of initial). The resulting 48 h EC50 for mobility was 63 mg/L. All criteria for acceptability of the test were met according to OECD guideline No. 202 and the study is considered to be reliable without restrictions.
