Description of key information
Additional information
Short term toxicity to fish: The purpose of this study according to OECD TG 203 was to estimate the acute toxicity of the test item to zebra-fish (Brachydanio rerio) under semi-static test conditions. The 96-hour LC50 value for the test item in zebra-fish was estimated to be >3200 mg/L.
Short-Term toxicity to aquatic invertebrates: The purpose of this study according to OECD TG 202 was to estimate the acute toxicity (EC50) of the test item to daphnia (Daphnia magna) under static test conditions. The 48-hour EC50 was calculated to be greater than 100 mg/L.
Toxicity to algae and cyanobacteria: The purpose of this study according to OECD TG 201A was to determine the effect of the test item on the growth of the freshwater green alga, Pseudokirchneriella subcapitata (formerly Selenastrum capricornutum). The 72 -h NOELR was estimated to be greater than 100 mg/L and the 72-hour ErC50 was calculated to be also greater than 100 mg/L.
Short-Term toxicity to microorganism: The objective of this study according to OECD TG 209 was to determine the effect of different concentrations of the test item on sewage sludge microorganisms by measuring the respiration rate under defined conditions. The EC50 value was calculated to be greater than 1000 mg/L The EC50 value for the reference substance 3,5-dichlorophenol was calculated to be 2.7 mg/L, which was within the acceptable limits (5.0 to 30 mg/L) as specified in OECD 209 Guideline. Thus, all validation criteria were fulfilled.
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.
