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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- PBT assessment does not apply
- Justification:
The PBT and vPvB criteria of Annex XIII to REACH Regulation (EC) No 1907/2006 shall not be applied to inorganic substances.
Persistence Assessment
The persistence criterion can only be applied to organic substances determining the lack of degradability of a substance which remains bioavailable. Inorganic metal compounds tend to be present in non-bioavailable forms so the key criterion for classifying inorganic metal compounds should be their capacity to transform in a bioavailable form.
Bioaccumulation Assessment
Similarly, the bioaccumulation criterion can only be applied to organic substances, based on lipid partitioning of the substances. In contrast, uptake of inorganic metals is not based on lipid partitioning. Furthermore, organisms have internal mechanisms to regulate the uptake of essential metals and to control the presence of other metals.
Toxicity Assessment
Only the toxicity criterion can be applied to inorganic metal compounds taking into account that the amount of soluble metal salts can be reduced by different media (by reducing the bioavaliable fraction of the metal). The toxicity criterion will not be fulfilled for ecotoxicity with no ecologically relevant NOECs less than 0.01 mg/L. However, the substance is classified as carcinogenic (cat. 1 or 2), mutagenic (cat. 1 or 2), or toxic for reproduction (cat. 1, 2 or 3) according to Directive 67/548/EEC or carcinogenic (cat. 1A or 1B), germ cell
mutagenic (cat. 1A or 1B), or toxic for reproduction (cat. 1A, 1B or 2) according to Regulation (EC) No. 1272/2008 according to Regulation (EC) No. 1272/2008. Thus, the criterion set out in Annex XIII of Regulation (EC) No. 1907/2006 is met and the substance is considered to meet the T criterion.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
