The 21-day NOEC of 5.6 mg/L for diethylene triamine is based on surivival and reproduction of Daphnia magna in a chronic toxicity test with diethylene triamine.
One long term test with Daphnia magnawas conducted with
diethylene triamine. This test was deemed reliable and useful for risk
assessment (Klimisch score = 2). In this test, D. magna were
exposed to four concentrations of diethylene triamine ranging from 5.6 -
45 mg/L and control dilution water for 21 days in a static renewal test
design. The pH of the test solutions was appropriately neutralized in
this study. Survival and reproduction were significantly reduced at 11.3
mg/L of diethylene triamine, but were unaffected at 5.6 mg/L.
