Description of key information
Sediment toxicity appears to be no matter of concern.
Key value for chemical safety assessment
Additional information
According to REACH Annex X, endpoint 9.5.1, column 2, long-term testing to sediment organisms shall be proposed by the registrant if the chemical safety assessment according to Annex I indicates the need to investigate further the effects on sediment organisms. Due to the absence of toxicity data for sediment organisms, the equilibrium partitioning method was applied to assess the hazard to sediment organisms.Valid available data on acute aquatic toxicity show, that graphite is not toxic up to the tested loading rate of 100 mg/L. No sublethal effects were observed. Graphite is not identified to be hazardous to the aquatic environment. Following the principles of the equilibrium-partitioning method, this hazard conclusion is extrapolated to the sediment compartment. Therefore, no further testing on toxicity to sediment organisms is considered to be required.
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.
