Description of key information

With high probability acutely not harmful to aquatic invertebrates.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
267.94 mg/L

Additional information

The acute toxicity of 1-methyl-1H-imidazole (CAS 616-47-7) to Daphnia magna was tested in a guideline study according to EU method C2. The EC0 value was determined to be 125 mg/L; the EC50 value was found to be about 267.94 mg/L after 48 h, based on nominal test concentrations (BASF AG, 1989; report no.: 1/0243/2/89-0243/89).

 

In conclusion, 1-methyl-1H-imidazole (CAS 616-47-7) is considered to be with high probability acutely not harmful to aquatic invertebrates.
