Additional information

[2-(perfluorohexyl)ethyl]silanetriol has a predicted water solubility of 0.58 mg/l. Results from the short-term aquatic toxicity tests show measured DOC concentrations above this predicted water solubility value. However, this value is subject to some uncertainty and the actual solubility may vary. An uncertainty of ±1.2 log units for the value of log (water solubility / mol/l) has been calculated using the regression statistics. Therefore, the measured DOC concentrations have been used for the calculation of PNEC.
