Additional information
A study was conducted to determine the short term toxicity of the read-across substance, benzenesulfonic acid C10 -13 -alkyl derivs., sodium salts to aquatic invertebrates according to OECD Guideline 202, in compliance with GLP. Daphnia magna were exposed to the test substance at nominal concentrations of 0 (control), 3.2, 5.6, 10, 18, 32, 56 and 100 mg/L for 48 h under static conditions. At some test concentrations, the daphnids moved irregularly and more slowly than controls. Immobile daphnids were observed from 32 mg/L. At 56 and 100 mg/L, all the daphnids were found to be immobile at 48 h. Under the sudy conditions, the nominal 48 h EC50 of the substance to Daphnia magna was 2.9 mg/L (nominal) (Hooftman, 1990).
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.
