Additional information
Key study (American Cyanamid Company, 87384 -0500 -2130, 1988)
A 21-day flow through toxicity test equivalent to OECD guideline 211 was conducted to estimate the chronic effects of the test substance to the water flea (Daphnia magna). The criteria for effect in the life cycle test were reproduction, growth, and survival of water fleas. Daphnia magna was exposed to the nominal concentrations of 0, 6.26, 12.5, 25, 50 and 100 mg/L corresponding to the mean measured concentrations of <2.63, 5.73, 11.7, 23.8, 45.6 and 97.1 mg/L. Since exposure to mean measured test item concentrations of 97.1 mg/L did not significantly reduce the survival, reproductive success, or growth of Daphnia magna, the NOEC was 97.1 mg/L.
