Additional information
Reliable studies are available for toxicity in invertebrates. A study using the saltwater species Artemia salina resulted in an EC50 value of 110mg/l. This was substantially lower than the 24hr interim EC50 of 810mg/l. In three other studies, 24hr values are available for D magna of 1260 and 4150mg/l and a 48hr LC50 of >1000mg/l.
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.
