Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on the intrinsic properties of the Reaction mass of (Gluconate)3Fe-Na3 and NaCl i.e. the relatively low soil-water partition coefficient and ready biodegradability of the Reaction mass of (Gluconate)3Fe-Na3 and NaCl
the substance will not partition to the soil compartment. Risk to soil organisms can be considered equal to the risk to aquatic organisms.
Additional information
No adsorption onto the organic fraction of soils or sediments is expected due to the ionic structure under environmental relevant pH conditions. Further more, the substance is readily biodegradable and significant exposure of organisms living in the terrestrial compartment to the Reaction mass of (Gluconate)3Fe-Na3 and NaCl is considered negligible.
Therefore no ecotoxicity tests have been performed for the terrestrial compartment because exposure of soil is considered to be negligible.
Because the soil organisms in the terrestrial environment are normally mainly exposed via the assumed application of surplus sludge from STP's. Because of the rapid biodegradation and negligible sorption this route to soil is considered negligible. An other route to soil could be the use as nutritional supplement in agriculture where the Reaction mass of (Gluconate)3Fe-Na3 and NaCl is applied via drip irrigation to supply the deficient iron to the plants. The amount of the Reaction mass of (Gluconate)3Fe-Na3 and NaCl applied is adjusted depending on the chemical analysis of the soil to a level which is just enough for efficient crop growth. Once the iron is released the gluconate is degraded. Because of the negligible sorption to soil the risk for soil organisms will be equal to the risk for aquatic organisms.
Due to the ionic structure under environmental relevant pH conditions, no adsorption onto the organic fraction of soils or sediments is expected. Based on this information and considering the observed ready biodegradability of the Reaction mass of (Gluconate)3Fe-Na3 and NaCl exposure of soil is considered negligible and therefore no terrestrial ecotoxicity tests have been performed.
The terrestrial PNEC is derived from the available aquatic toxicity data and the Koc using the equilibrium partitioning method.
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).
