Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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

No reliable data are available for the effect of synthetic rutile on soil microorganisms and read-across to upgraded ilmenites (UGI) is used. Reliable chronic toxicity data are available for the effect of upgraded ilmenite slags (>80% TiO2) to the nitrification activity in a natural soil. The lowest NOEC was 10,000 mg/kg dw (observed for the UGI slag RBM SO4).

Key value for chemical safety assessment

Long-term EC10 or NOEC for soil microorganisms:
10 000 mg/kg soil dw
