Description of key information
The EC50 for aquatic invertebrates exposed to dimethylammonium 2,4-dichlorophenoxyacetate was determined to be 168 mg test substance/L (86.64 mg a.i./L)
Key value for chemical safety assessment
Additional information
One study investigating the acute toxicity of dimethylammonium 2,4-dichlorophenoxyacetate (CAS No. 2008-39-1) to Daphnia magna is available (Raszka, 1995). This test was performed according to OECD Guideline No. 202: Daphniasp., Acute Immobilisation Test (1984). After 48 hours exposure to the test material, immobilisation of daphnids at the highest concentrations was reported. The resulting EC50 was 168 mg test substance/L (corresponding to 86.64 mg a.i./L). Additional information could be gathered from the review report on 2,4-D acid (European Commission, 2001) in which a 48h-EC50 = 100 mg a.i./L for Daphnia magna is stated.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
