Additional information

Statement literature and substance evaluation:

A large number of studies identified during the literature search applied so-called titanium dioxide as test item without any or with limited documentation on the identity of the tested substance. It is problematic to base the hazard and risk assessment of clearly characterised titanium dioxide on information generated with poorly characterised test items that are without any market relevance. Consequently, all studies conducted with self-synthesised titanium dioxide nanomaterials were rated not relevant for hazard and risk assessment purposes (in accordance with ECHA Guidance Chapter R.4: Evaluation of available information, Version 1.1, December 2011). Furthermore, all references obtained during the literature search were evaluated according to the criteria laid down in ECHA Guidance R.4 (Version 1.1, December 2011), the OECD Guidance Document 34 (2005) and the reference by Klimisch et al. (1997). The screening foresees an incremental procedure evaluating the relevance, reliability and adequacy (for further information refer to the attached statement on the literature evaluation criteria in IUCLID section 13).

Conclusion on classification

Acute and chronic aquatic toxicity data for micro- and nanosized TiO2 are available for three trophic levels.

 

Toxicity endpoints do not meet the classification criteria of short-term aquatic hazard Category 1 and Long-term aquatic hazard Category 1, 2 and 3. Thus, classification as hazardous to the aquatic environment is not required according to Regulation (EC) No 1272/2008.
