- no
Test organisms
- Test organisms (species):
- Daphnia magna

- Total exposure duration:
- 48 h
Results and discussion
Effect concentrations
- Duration:
- 48 h
- Dose descriptor:
- EC50
- Effect conc.:
- > 1 000 mg/L
Any other information on results incl. tables
EC50 (48 hours) Titanox (TM) 1000 = > 1000
mg/l
EC50 (48 hours) Tronox (TM) CRX = > 1000 mg/l
EC50 (48 hours) Tioxide (TM) R-FC6 =
> 1000 mg/l
EC50 (48 hours) Tiona (TM) RCL-69= > 1000 mg/l
After 24 hours in test, all the titanium dioxide had settled to the
bottom of the test vessel, except for the Tronox (TM) CRX sample. This
material stayed in suspension allowing ingestion to occur for the entire
48-hour duration of this test.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
