Description of key information
The 10-day LC50 for Corophium volutator was calculated as > 10000 mg/Kg, based on nominal sediment concentrations. All parameters measured in this study lay within acceptable tolerance limits.
Key value for chemical safety assessment
- EC50 or LC50 for marine water sediment:
- 10 000 mg/kg sediment dw
Additional information
The acute toxicity of the test substance, organolignite, to sediment reworker, Corophium volutator, was determined in accordance with test method PARCOM (1995). Invertebrates were exposed in semi-static conditions for 10 days to nominal sediment concentrations of 1000.0, 1778.0, 3162.3, 5623.4, and 10000 mg/Kg. The 10-day LC50 was determined to be > 10000 mg/Kg. No deviations to study protocol were noted except that no parameters or observations were conducted on day 1 of the study.
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.
