Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Data are available for two short-term studies on fish:
The assessment of the 96 h LC50 of FeNaEDTA in fish was done in an acute test on the rainbow trout Onchorhynchus mykiss according to the OECD Guideline 203, EC method C.1 (92/69/EEC) and US EPA OPPTS 850.1075. The test item was evaluated in a static test under GLP (Bormann 2007, KEY study, Reliability 1).
No mortalities of fish occurred up to a concentration of 100 mg/L within a period of 96 h. The mean measured concentration of the test item was between 80 and 120% of the nominal through the entire test period and the toxicological endpoints were evaluated using nominal concentration of the test item. The LC50 (96h) was determined to be > 100 mg/L with a probability of 99.9%. The NOEC (96 h) was determined to be 100 mg/L.
The acute toxicity (96h-LC50) of sodium ferric EDTA towards Pimephales promelas was investigated according to EPA-600/3 -75 -009 and ASTM method E729 -80 in a multispecies test (published paper by Ewel et al, 1986, Reliability 2). The toxicity value was found to be >100 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.
