Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Lanthanum fluoride

Short-term toxicity to soil macro-organisms

-

14d-NOEC (E. foetida) > 1000 mg/kg

-

-

Long-term toxicity to soil macro-organisms

Waived based on the terrestrial data already available

-

-

Long-term toxicity to terrestrial arthropods

Waived based on the terrestrial data already available

-

-

Short-term toxicity to terrestrial plants

-

17/18d-NOEC (A. sativa,L. sativa,B. rapa)

> 1000 mg/kg

-

-

Long-term toxicity to terrestrial plants

Waived based on the terrestrial data already available

-

-

Toxicity to soil micro-organisms

-

28d-NOEC (carbon mineralizing bacteria)

> 1000 mg/kg

-

-

Toxicity to birds

Waived based on a low bioaccumulation potential and on the absence of toxicity in mammalian tests

-

 

Based on the already reported data showing similar physico-chemical, environmental and ecotoxicological properties of the reaction mass and its constituent, read-across with constituents when data are not available on the reaction mass appears fully relevant.
