Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Some experimental data (published scientific literature and grey literature) were identified informing on the toxicokinetic behaviour of yttrium. These data, together with information on the physicochemical characteristics of yttrium, are used to perform a qualitative assessment of the absorption, distribution/metabolism and elimination of yttrium metal.

The absorption of yttrium metal is assumed to be very limited and the following absorption factors were established: oral 1%, inhalation 1%, and dermal 1%. A detailed toxicokinetic evaluation is attached in section 13.

Key value for chemical safety assessment

Additional information

A detailed toxicokinetic evaluation is included in section 13.
