Description of key information

In two tests, the acute toxicity of Multi-Walled Carbon Nanotubes (MWCNT)  for Daphnia magna was determined. No effects have been observed (48h-EC50 > 100 mg/L, nominal) (Weyers, 2006b).

In another test at the highest concentration mortality was 20% and significantly different from controls, but lower than 50%. Therefore it can be concluded that the EC50 value for acute effects on daphnia for MWCNT is higher than 100 mg/l (Weltens, 2010a).

Test material is meeting the form as described in section 4.5 of the IUCLID dossier.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
100 mg/L

Additional information

EC50/LC50 for freshwater invertebrates should read >100 mg/L
