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.
