The log Koc value was predicted with the program KOCWIN and with three QSPR methods. The resulting geometric mean of log Koc = 4.165 (Koc = 14622 L/kg) is considered as valid as it is being supported by several different QSPR approaches.It is proposed to use the predicted value for the adsorption coefficient of log Koc = 4.165 in the chemical safety assessment.The substance is considered to be immobile in sediments and soil (McCall et al. 1981).
As additional adsorption/desorption testing cannot be expected to reveal new results with any added value concerning the risk assessment of this substance, additional Annex IX studies on adsorption/desorption shall be waived.
Henry's law constant:
This information is not available. The Henry's law constant can be calculated (EUSES 2.1.2) from the available information on the physical-chemical properties of the substances, giving a value of 28.6 Pa· m3/mol.The substance is considered as moderately volatile under environmental conditions.
