ADSORPTION / DESORPTION

The registration substance has a measured Log Kow of 3.3 and based on this value the Exposure Modelling Program EUSES 2.1 calculates a Koc of 544 L/kg ; logKoc=2.73 (QSAR for non-hydrophobics) corresponding to a Kd soil of 10.9 L/kg, Kd sediment of 27.2 L/kg and Kd activated sludlge of 201 L/kg. These Kd values are low which means that an Adsorption / Desorption study is not warranted.

AIR - WATER PARTITIONING

Based on the measured water solubility of the registration substance of 25 mg/L at 20 deg C (see IUCLID Chapter 4.8) and a calculated vapour pressure of <0.001 Pa at 25 deg C the Exposure modelling program EUSES 2.1 calculates a Henry's Law Constant of 1.14 E-02 Pa*m3/mol at 12 deg C and a dimensionless Air-water partitioning coefficient of 4.79 E-06 m3/m3 at 12 deg C.
