With high probability acutely not harmful to aquatic invertebrates
In a static GLP test according to EU method C.2 the acute toxicity of
the substance to Daphnia magna was investigated (BASF 1998). After 48
hours no effects were observed in the highest nominal test concentration
of 100 mg/L, indicating that the EC0 and EC50 are well above 100 mg/L.
Due to the analytics, an arithmetic mean concentration of 74.7 mg/L was
estimated. As already stated no effects occured in the highest
concentration. Therefore, it is assumed that the substance is not
harmful to aquatic invertebrates. Due to product saftey reasons the
measured arithmetic mean value of 74.7 mg/L is used for the subsequent
hazard assessment of the substance.
