Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key value for chemical safety assessment
Additional information
IODINE:
Short description of key information:
50 day chronic plant study (Brassica rapa) NOEC (seed dry weight) 10 mg I kg -1 soil (clay soil)
50 day chronic plant study (Brassica rapa) EC50 (seed dry weight) 38 mg I kg -1 soil (clay soil)
Key value for chemical safety assessment:
Short-term EC50 or LC50 for terrestrial plants: 38 mg/kg soil dw.
Long-term EC10/LC10 or NOEC for terrestrial plants: 10 mg/kg soil dw.
Discussion:
The reviewed study investigated the toxicity of inorganic iodine (applied as KI) to the terrestrial plants, Brassica rapa, (life cycle bioassay), and Lactuca sativa (seed germination bioassay) in three soil types, clay soil, sand soil and garden soil. This use of KI as the test substance, is considered relevant for read across to iodine as iodide is the major existent species of iodine in soil which is available for interactions with soil components. For further information, refer to the environmental fate section of the dossier. The protocol is not conducted to any test guidelines (e.g. OECD Guidelines) but follows scientific principles and is well documented, supporting a Klimisch score of 2 - reliable with restrictions. The most sensitive NOEC in clay soil was 10 mg/kg soil dw (seed dry weight) and the most sensitive EC50 was 38 mg/kg soil dw (seed dry weight). Refer to the attached endpoint study record for further details.
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.
