Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Any other information on results incl. tables

Yttrium is one of the rare earth metals. The estimated abundance in the earth's crust is 28 -31 ppm.

Monazite sand contains 3% Y and bastnasite about 0.2%. Xenotime contains about 60% Y. The abundance of yttrium in the earth's crust is about 0.0028% or 28 ppm. It is not known to which extent the environmental concentrations of yttrium have been increased by anthropogenic activities. For sea water concentrations of y3+ of 0.01 to 0.3 ppb are given in the literature. For uncultivated soils concentrations of 2.5 -250 ppm have been reported.
