Additional information

The toxicity of test material to daphnids was evaluated according to the OECD Guideline 202. Twenty daphnids, divided in groups of five, were exposed to different concentrations of the substance ranging from 2200 and 10000 mg/l. After 24 h in darkness, the immobilization of the daphnids was measured. The daphnids that were unable to swim for 15 s after gentle stirring were considered immobile; EC50 (24h) = 6234 ± 466 mg/l (nominal)

The EC50 at 48 hours was predicted by ECOSAR v.1.1 to be 75611.781 mg/l which supports that the substance is not expected to be toxic to daphnia.
