Description of key information
Additional information
Short-term toxicity to fish
The short-term toxicity to the Golden Orfe was tested in OECD Guideline 203 equivalent study without GLP and analytical verification of test item concentrations. A 96h-LC50 in the range of 10 - 22 mg/L (based on nominal concentrations) was reported.
Short-term toxicity to aquatic invertebrates
The short-term toxicity to daphnids was tested in a study according to OECD Guideline 202 under GLP. For computation of the EC50 the nominal test item concentrations were adjusted by the test item recovery rate analytically determined at test item concentration 100 mg/L. In this way a 48h-EC50 of 4.92 mg/L was determined (48h-EC50 = 79.8 mg/L based on nominal concentrations).
Toxicity to micro-organisms
An activated sludge respiration inhibition test according to OECD Guideline 209 was conducted under GLP. The EC50 was determined to be >1000 mg/L based on nominal concentrations.
Classification and Labelling:
Dangerous Substance Directive (67/548/EEC)
The available studies are considered reliable and suitable for classification purposes under Directive 67/548/EEC. As a result and according to the harmonised Annex I classification the substance is considered to be classified as N; R51 - 53 under Directive 67/548/EEC, as amended for the 31st time in Directive 2009/2/EG.
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. As a result and according to the harmonised Annex VI classification the substance is considered to be classified Aquatic Chronic 2 (H411) under Regulation (EC) No 1272/2008, as amended for the sixth time in Regulation (EC) No 605/2014.
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.
