The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

No reliable acute toxicity data on fish are available for synthetic rutile. Read-across is proposed to TiO2. Reliable toxicity data on aquatic organisms are available for a range of TiO2 products with varying particle size (from nano-particles to bulk powders). For aquatic toxicity we can conclude that algae are the most sensitive species. Only unbounded L(E)C50 values are available for both fish and invertebrates, ranging from >1 to >10000 mg TiO2/L. The lowest L(E)C50 value was observed for growth rate of the freshwater algae Pseudokirchneriella subcapitata: 61 mg TiO2/L, with a corresponding chronic EC10 of 12.7 mg TiO2/L.
