Not appropriate, environmental partition coefficients (Kp or Kd) to be used instead
This endpoint is covered by the category approach for soluble iron salts
(please see the section for physical and chemical properties for the
category justification/report format). Testing for this endpoint has
been waived in accordance with column 2 restrictions. The solubility of
iron salts in organic solvents such as octanol is low. The ferric or
ferrous ion undergoes a series of reactions in aqueous solution which
result in the formation of highly insoluble oxo-hydroxides. However, the
initial solubility in water is high. Anyhow the Octanol/water partition
coefficient is a property of interest and relevance for organic
substances only and not appropriate for inorganics such as metals and
measured environmental partition coefficients (Kp or Kd) should be used
instead (ECHA 2008, Guidance on information requirements and chemical
safety assessment, Appendix R.7.13-2: Environmental risk assessment for
metals and metal compounds, p 12).
