Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
COPPER IODIDE
Biodegradation as used for organic substances does not apply to inorganic substances such as copper iodide, although attenuation of the toxicity is observed. This fact was recognized in the Guidance to Regulation (EC) No 1272/2008 Classification, Labelling and Packaging of substances and mixtures (metal annex).
Summary information on the Environmental Fate of copper and iodine is also presented below.
COPPER
Biodegradation as used for organic substances does not apply to inorganic substances such as copper and its compounds, but attenuation of the toxicity is observed.
This was recognized in the Guidance to Regulation (EC) No 1272/2008 Classification, Labelling and Packaging of substances and mixtures (metal annex): “Environmental transformation of one species of a metal to another species of the same does not constitute degradation as applied to organic compounds and may increase or decrease the availability and bioavailability of the toxic species. However as a result of naturally occurring geochemical processes metal ions can partition from the water column. Data on water column residence time, the processes involved at the water – sediment interface (i. e. deposition and re-mobilisation) are fairly extensive, but have not been integrated into a meaningful database. Nevertheless, using the principles and assumptions discussed above in Section IV.1, it may be possible to incorporate this approach into classification".
For more information: see summary "environmental fate and pathways" and "additional information on environmental fate".
IODINE
Because iodine is an elemental inorganic substance aerobic or anaerobic biodegradation are not considered to be relevant. Thus, no studies on biodegradability have been conducted or submitted.
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.
