General Information

Not classified
Implementation:
EU
Remarks:

Only studies performed with Multi-Walled Carbon Nanotubes (MWCNT) meeting the form described in section 4.5 of the IUCLID dossier are considered to be relevant for this submission.

Although a large number of studies on MWCNT have recently been published, clear characterisation of the test materials including sample preparation is often missing although this is quite essential for ensuring reproducibility and reliability of a study. Importantly, modifications of some specific characteristics of the MWCNT tested such as variations in tube diameter or length distribution might give rise to differences in the (eco-) toxicological profile.  

Effects of different MWCNT seem to depend on the form (length) and physico-chemical properties (metal content, aggregation/agglomeration, surface chemistry, and functionalisation). Thus, for the time being a case-by-case approach is appropriate and the hazard assessment for MWCNT meeting the form described in section 4.5 of the IUCLID dossier is based solely on the information collected with this form of MWCNT. That is the reason why a comprehensive documentation is restricted to all available and relevant data on MWCNT meeting the form described in section 4.5 of the IUCLID dossier. That means on the other hand that the values used for any risk assessment should not be used for all MWCNT or for CNT in general, as the results obtained with one particular type of MWCNT may not necessarily be relevant for other CNT with other dimensions and properties.
