Highest test concentration resulting in 0% immobilisation (EC0 48h): >= 100 mg/1

The results are expressed in terms of nominal concentrations (at 24h and 48h). Recovery rates correspond to 87.4% of nominal values at 0 hours, and to 89.6% of nominal values at 48 hours, respectively.

The hardness of the dilution water used was 15.1 °dH (= 269.54 mg/1 CaCO3).
