Description of key information
Additional information
Toxicity to fish, aquatic invertebrates, and algae:
Experimental short-term fish and invertebrate data for the registered substance exhibit acute aquatic toxicity >0.1 and <=1mg/L. Experimental data for algae exhibited ErC50 and NOErC values of 3.2 mg/L and 2.2 mg/L, respectively. QSAR results for long-term fish and invertebrate for the registered substance estimate chronic toxicity >0.01 and <=0.1 mg/L. This supporting QSAR information is provided by acute and chronic aquatic toxicity values calculated using the neutral organics structure-activity relationship in the ECOSAR computer program (Nabholz and Mayo-Bean, 2009) of EPISuite. Validity and applicability of the QSAR are described in a document attached as background material to the QSAR endpoint study record.
Measured data demonstrate that the QSAR estimations accurately predict aquatic effects from short and long-term continuous exposure to the registered substance (as is obtained under test conditions).
Toxicity to microorganisms:
In a test for Nitrification Inhibition using Nitrosomonas sp., Alcohols, C11-14-iso, C13-rich exhibited no inhibition at the highest nominal concentration tested. This resulted in a 4-hour NOELR (No Observed Effect Loading) of 105.3 mg/l, based on nitrification rate.
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.
