Additional information

The acute toxicity to Daphnia magna was evaluated in a 48 -hour static test according to the EU Method C.2 of the EEC Directive 84/449. Twenty animals were exposed to five nominal concentration in the range of 31.25 to 500 mg/L and a control without any additions. In the control no immobilization of the daphnia was observed. The EC50 was found to be greater than 500 mg/L (nominal) after 48 hours.

Although no analytical determination of tested concentration was performed, the substance was reasonably expected to be stable over the entire test period: it is not biotically and/or abiotically readily degradable; in addition, there are no reasons to suspect the occurance of deposition/flocculation phenomena.
