Description of key information
Additional information
Studies on aquatic toxicity of the test substance are not available. However, results on aquatic toxicity are given in the NATIONAL INDUSTRIAL CHEMICALS NOTIFICATION AND ASSESSMENT SCHEME (NICNAS; File No: STD/1346, January 2010) by the Australian Department of the Environment, Water, Heritage and the Arts. In the assessment, data on acute toxicity to fish, dapnids and algae are given. After 96 h of semi-static exposure a LC50 of > 100 mg/L (measured) was determined in an OECD 203 guideline study using Common Carp and including analytical monitoring. In a static OECD 202 guideline study using Daphnia magna and including analytical monitoring an EC50 of 31.23 mg/L (measured) has been determined after 48 h of exposure. The most sensitive value was identified in a toxicity study to aquatic plants. An OECD 201 guideline study using Pseudokirchneriella subcapitata and including analytical monitoring gave an EC50 (growth rate) after 72 h of exposure of 0.0465 mg/L (measured). The NOEC (growth rate, 72 h) was determined to be 0.004 mg/L. Therefore, the test substance is regarded as very toxic to aquatic organisms.
In all acute toxicity studies DMSO has been used as solvent.
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.
