Additional information

Aquatic toxicity

There are no chronic toxicity data, but due to the known inherent physico-chemical properties, absence of acute toxic effects as well as the ubiquitous presence of carbon in the environment, there is no evidence of harmful long-term effects arising from exposure to carbon black. The generation of long-term toxicity data has been waived.

The fish and invertebrate LC50 and EC50 data are dominated by physical and pH considerations, and treatment of these results by methodology appropriate to a chemical toxicity mechanism may not be appropriate.

Terrestrial and sediment toxicity

No data available, generation of data has been waived

Conclusion on classification

No classification as to environmental hazards required.
