Additional information

Acute tests on all three trophic levels were performed to examine the acute aquatic toxicity of 2, 2’, 2’’-nitrilotriethanol. Additionally, a chronic test on aquatic invertebrates is available.

Daphnia magna turned out to be the most sensitive species with a reproduction NOEC of 16 mg/l after 21 days of exposure. Effects of 2, 2’, 2’’-nitrilotriethanol towards fish and algae were found at a LC50 (96h) of 11800 mg/l and an ErC50 (72h) of 512 mg/l, respectively.

Thus, 2, 2’, 2’’-nitrilotriethanol is considered not acutely harmful for aquatic organisms.
