Nominal and measured concentrations:
1 mg/L nominal:
Analytical monitoring of the concentration of the test substance in the test water was not conducted since no relevant results could be expected. The solubility limit of the test substance is below the analytical detection limit. From the properties of the test substance it could be concluded that the test substance was chemically stable in water over the test intervals of 48 and 72 hours, respectively. Due to the very low solubility of the substance it can be estimated, that the actual concentration is smaller or equal to 20 µg/L.
