Administrative data

adsorption / desorption: screening
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance has a low octanol water partition coefficient and the adsorption potential of this substance is related to this parameter
Justification for type of information:
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.
