Description of key information
According to Annex XI, Section 2 of
Regulation (EC) No 1907/2006 (REACH) testing for a specific endpoint
may be omitted if it is technically not possible to conduct the study
as a consequence of the properties of the substance itself. A study to
investigate the adsorption / desorption characteristics of lithium
fluoride has not been conducted. The justifications for not providing
these data are as follows:
- A screening study according to OECD Guideline 121 is not technically
possible as the test method is not validated for inorganic substances.
- A batch equilibrium study according to OECD Guideline 106 was deemed
to be not applicable to lithium fluoride for the following reasons:
Firstly, both lithium and fluoride are natural constituents of soils and
as such analysis of the test material may not be possible due to
interference from the soil extracts that may leach into the aqueous
media during the test. This would prevent quantification of the test
material.
In addition, the mobility of the test item would be dependent on the
anion exchange capacity of the soils as the main component of the test
material is an anion. This absorption relationship would not be
anticipated to correlate with the organic carbon content of the soils
and is considered to be beyond the scope of the OECD 106 method.
Furthermore, the test on adsorption/desorption screening does not need
to be conducted if the substance can be expected to have a low
potential for adsorption based on the octanol/water partition
coefficient. Lithium fluoride completely dissociates in water forming
lithium cation and the corresponding fluoride anion, therefore the log
Pow of hydrofluoric acid was calculated. The theoretical, calculated
(EPIWIN) log Pow for hydrofluoric acid is 0.23, i.e. very low and no
adsorption is expected.
Key value for chemical safety assessment
