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 adsorption/desorption test does not need to be conducted as based on the physico-chemical properties, the substance can be expected to have a low potential for adsorption as the maximum log Kow is 3.95 (experimental study), therefore, the organic carbon-water partitioning coefficient (Koc) is calculated from the log Kow using EUSES (predominantly hydrophobics QSAR). The calculated Log Koc value is 3.3. As further studies on transport and distribution in the environment are not available, this predicted value is used in the assessment.
As a rule of thumb, substances with log Koc > 4 are generally regarded as highly adsorptive and likely to distribute in sediment and soil. Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.11: PBT/vPvB assessment, Version 3.0, June 2017
