Additional information
A study was performed to assess the acute toxicity of test substance to Zebra fish (Brachydanio rerio) under static conditions. The study was conducted in accordance with EU Method C.1. and OECD Guideline 203.
Groups of ten fish of the recommended size were exposed to a limit test concentration of nominally 100 mg/L of test substance dissolved in water. Analysis was performed for the test concentration plus a control on daily basis. All results are expressed in terms of mean measured concentrations.Measured concentrations correspond to 85.9, 85.9, 81.8, 81.8 and 85.9% of nominal values at 0, 24, 4, 72 and 96 h respectively. The hardness of the dilution water used was 11.6 °dH (=207.1 mg/L CaCO3).
Observations were made on the number of dead fish and the incidence of sub-lethal effects after 2, 24, 48, 72 and 96 h of exposure.

The 96 h LC0 value of the test substance (including inorganic components) was determined to be ≥84.3 mg/L (Dr. Bruns, 2002).
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.
