Additional information
The toxicity of 3-(chloromethyl)heptane (CAS 123 -04 -6) to aquatic invertebrates was tested withDaphnia magnaaccording to OECD 202 (Daphnia sp. Acute Immobilisation Test). The Daphnids were exposed under static conditions in sealed vessels to slow evaporation. The test concentrations were analytically verified. The determined 48 -h EC50 was 0.375 mg/L (mean measured; BASF, 2012, project no. 50E0397/11E107). The study is supported by a result of an OECD 202 immobilization test with Daphnia magna, conducted by Evonik Degussa GmbH (2003). The 48 -h EC50 was determined to be 1.3 mg/L (nominal; analytically verified). The daphnids used in this test were less sensitive compared to them in the BASF SE study (2012) regarding the 24 -h EC50 with the positive control (potassium dichromate). Considering the worst-case scenario, the lower EC50 determined by BASF SE (2012) was used for the aquatic toxicity assessment. Therefore, the test substance is acutely very toxic for aquatic invertebrates.
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.
