Additional information

No specific chronic data were available for EDTA-ZnK2. (see for read across the document in section 13)

The selected and recalculated acute endpoint values for EDTA-ZnK2 were 740, 119 and 721 mg/L for fish, daphnids and algae

respectively. Chronic endpoints were >= 40.5, 32.1 and 47.5 mg/L for fish, daphnids and algae respectively.

Both from acute as well as chronic data, daphnids show the most sensitive species.

Meaningful results with algae tests were obtained by studies avoiding limitation of essential nutrients.

For microorganisms, from an active sludge respiration test it was concluded that the highest dose tested did not cause significant effects, a NOEC was detemined >= 710 mg/L EDTA-ZnK2.
