Additional information

The acute toxicity of the test item was tested in a static immobilisation assay with Daphnia magna. The assay was conducted according to EU method C.2. The daphnia were exposed to nominal concentrations of 3.2, 6.3, 12.5, 25, 50, and 100 mg/L for up to 48 h. Test subjects were observed for alterations of the normal mobility behaviour and loss of locomotory activity. From the data obtained through these observations, the effective concentration 0% (EC0) and the effective concentration 100% (EC100) for immobilisation induced by an exposure to the test item for 24 h were determined as 25 and 100 mg/L, respectively. For an exposure period of 48 h, the respective values were 11.35 and 92.35 mg/L. Furthermore, effective concentration 50% (EC50) values of 37.7 and 26.6 mg/L were determined for the 24 h and the 48 h exposure, respectively.
