Additional information

No specific chronic data were available for EDTA-ZnNa2.

The selected and recalculated acute endpoint values for EDTA-ZnNa2 were 685, 110 and 667 mg/L for fish, daphnids and algae

respectively. Chronic endpoints were >= 37.5, 29.7 and 44 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 >= 658 mg/L EDTA-ZnNa2.
