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

By analogy with FeNaEDTA (CAS 15708-41-5), EDTAFeHNa is not considered as harmful for the fish species tested.

Key value for chemical safety assessment

Fresh water fish

Fresh water fish
Effect concentration:
100 mg/L

Additional information

One GLP-compliant study is available on the analogue, FeNaEDTA. It is quoted as reliability 2 according to Klimisch criteria (as the data is used in a read-across approach), flagged as a key study and considered as acceptable for the risk assessment.

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 2).

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.

Additionally, 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.
