Additional information
The acute toxicity of 2 -ethyl-4 -methylimidazole (CAS 931 -36 -2) to aquatic invertebrates was test in a static test according to the EU method C2 of Annex V to Directive 79/831/EEC. The test species was Daphnia magna. The test concentrations were not analytically verified but are assumed to be stable. The 48 -h EC50 was determined to be 297 mg/L (nominal; BASF AG, 1990; report no. 1/0245/2/89 -0245/89). It can be concluded that with high probability 2-ethyl-4-methylimidazole is acutely not harmful to aquatic invertebrates.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
