Additional information

A 21 -day chronic study on Dapnia magna resulted in a NOEC for survival and reproduction of daphnids of 0.059 mg/L.

Another report of a 21 -day chronic test described no adverse effects on the reproduction of daphnia magna when compared with the test medium control or dispersion control. The NOEC was estimated to be 1.0 mg/L and the EC50 >1.0 mg/L. Solubilising agents were used to increase concentration of the substance beyond its water solubility.
