Description of key information
With high probability acutely not harmful to fish. No acute toxic effects occur within the range of solubility.
Key value for chemical safety assessment
Additional information
A study on the acute toxicity to fish is not available for the test item. However, studies on acute toxicity on fish of two structural analogues are available. In general, the analogue substances are composed of a structurally analogue organic part laked with different divalent metals (Ca2+, Sr2+, Ba2+, Mn2+). At environmentally relevant pH values a disintegration of the molecule and a release of the metal component is not expected. Therefore, an influence of the laked metal part is not likely. Thus, a transfer of the results of the acute toxicity studies on structural analogues is justified (see Annex).
In a study on CAS 7585-41-3 following OECD guideline 203 Brachydanio rerio were exposed to the substance for 96 hours in a static test system. Based on mortality a LC50 > 100 mg/l was determined (RCC Ltd, 2007). Due to the low solubility of the test substance a water accommodated fraction was tested. No acute toxic effects occurred within the range of solubility. A comparable result was obtained by a study on CAS 7023-61-2. The study was conducted in compliance with OECD guideline 203 and GLP. After 96 hours exposure time a LC50 > 100 mg/l was detected using zebra fish (BASF AG, 2000). As well, since the test substance was sparingly soluble in water, a saturated solution was used and no acute toxic effects occurred within the range of solubility.
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.
