Description of key information

ADSORPTION / DESORPTION

The registration substance has a measured Log Kow of 1.6 and based on this value the Exposure Modelling Program EUSES 2.1 calculates a Koc of 19.1 L/kg (QSAR for organic acids) corresponding to a Kd soil of 0.381 L/kg, Kd sediment of 0.953 L/kg and Kd activated sludlge of 7.05 L/kg. These Kd values are low which means that an Adsorption / Desorption study is not warranted.

AIR-WATER PARTITIONING

Based on the vapour pressure and water solubility of the registration substance EUSES 2.1 calculates a Henry's Law Constant (HLC) of 7.6 E-04 Pa*m3/mol at 12 deg C or dimensionless 3.2*E-7 m3/m3.
