Additional information

In a study performed according to the OECD guideline 209 ( Desmares-Koopmans, 2011), N-(3 -aminopropyl)iminodiethanol (APDEA) was not toxic to waste water (activated sludge) bacteria at or below a loading rate of 220 mg/L (NOEC), corresponding to 200 mg/L based on the active ingredient. The EC10 was at a loading rate of 205 mg/L (186 mg a.i./L). The EC20 was at a loading rate of 314 mg/L (285 mg a.i./L). The EC50 and the EC80 were above the highest loading rate tested, 1000 mg/L (907 mg a.i./L).
