Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
Additional information
A Daphnia immobilisation test (Huntingdon Life Sciences, 2011) was conducted to assess the potential for Fe3P to affect aquatic invertebrates. The study was conducted according to EC guideline C2 and OECD guideline 202, and in compliance with GLP.
Following preliminary tests, a definitive test was conducted at a limit concentration of nominally 100 mg/L; the test solution was passed through a 0.2 µm filter to ensure that the test solution used in the test only contained test material in aqueous solution. Due to low aqueous solubility, the measured concentration in the test solution at the beginning and end of the exposure period was below the limit of quantification of the analysis method used, and was estimated at 0.03 mg/L.
No Daphnia were seen to have been immobilised during the 48 -hour exposure period, and so the EC50 could not be calculated, however it must be greater than 0.03 mg/L. The No Observed Effect Concentration (NOEC) was 0.03 mg/L.
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.
