Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

One reliable 35 d early life stage study on chronic toxicity to zebrafish (danio rerio) of the substance EDTA-CaNa2 is available from BASF. This is therefore the key study. The NOEC is >= 35.1 mg/L based on nominal concentration, expressed as EDTA-CuNa2 this would be 37.2 mg/L.

Key value for chemical safety assessment

Dose descriptor:
The long-term toxicity test was performed with EDTA-CaNa2. For the EDTA-CuNa2 dossier the results was recalculated using the ratio of the MW's. 35.1 * 397.7/374.27 = 37.3 mg/L
Effect concentration:
>= 37.3 mg/L

Additional information

Since no chronic adverse effects have been determined in this study the NO(A)EC is a >= value, which can't be expressed in the box above. The NOAEC is >= 36.9 mg/L, based on mean measured concentration of EDTA-CaNa2, but >= 35.1 mg/L based on nominal concentration, or expressed as EDTA-CuNa2 >= 37.3 mg/L.
