Description of key information
The 48 hour LC50 for the marine crustacean Acartia tonsa was calculated as > 2000 mg/L based on nominal Water Accommodated Fractions (WAFs) concentrations. There was no evidence of a dose response.
Key value for chemical safety assessment
Marine water invertebrates

Additional information
The acute toxicity of the test substance, organolignite, to the marine crustacean, Acartia tonsa, was determined using test method, ISO 14669: 1999 (E). Animals were exposed in static conditions for 48 hours to nominal water accommodated fractions (WAFs) containing concentrations of the test substance of 200.0, 355.7, 632.5, 1124.7, and 2000.0 mg/L. After 48 hours, the LC50 was determined to be > 2000.0 mg/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.
