Long-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
Description of key information
The substance is very toxic to aquatic organisms with long lasting effects.
NOEC (21d) = 2 µg/L and LOCE (21d) = 6.4 µg/L (measured, TWA) for Daphnia magna (OECD 211)
Key value for chemical safety assessment
Additional information
The long-term toxicity on aquatic invertebrates was investigated with the waterflea Daphnia magna, in a GLP guideline study according to OECD 211 [BASF SE, 2013]. Due to the low water solubility, a saturated solution of the test item was prepared. After an exposure of 21 days the NOEC was 2 µg/L and the LOEC was 6.4 µg/L based on reproduction (measured, TWA).
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.
