Additional information

In accordance with section 1 of REACH Annex XI, the study on bioaccumulation does not need to be conducted, based upon on low bioavailability of the category members as described in the guidance document on information requirements and chemical safety assessment, Chapter R.7. 13-2: Environmental risk assessment for metals and metal compounds. The substances are highly insoluble in water, out of toxic response to aquatic organisms, and based upon its physico-chemical properties the category members do not bind to biological ligands.More detailed information can be found in the document "White paper on secondary poisoning of Fe and Al compounds (Arche 2010).

For the impurity LEAD:

From the literature overview, the following bioaccumulation/bioconcentration factors have been derived for Pb:    

 - Aquatic compartment

Bioaccumulation/bioconcentration factors in freshwater: 1,553 L/kg

- Soil compartment

Bioaccumulation/bioconcentration factors in soil: 0.39 kg/kg (dry weight)
