Description of key information

No chronic data are available for EDTA-Zn(NH4)2. 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 and recalculated as EDTA-Zn(NH4)2 the NOEC >= 36.6 mg/L .

Key value for chemical safety assessment

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. For EDTA- Zn(NH4)2, the recalculated NOAEC is >= 38.4 mg/L, based on mean measured concentration, but >= 36.6 mg/L based on nominal concentration.
