Description of key information
Additional information
The ability of the substance to adsorb to soil was investigated in a screening study in accordance with the standardised guidelines OECD 121 and EU Method C.19 under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
The soil adsorption/desorption screening test was carried out using the HPLC estimation method at a column temperature of 30 °C in a mobile phase of methanol : reverse osmosis water (55:45 v/v). As the test material is a salt of a dicarboxylic acid, testing was performed at a neutral pH with the test material in its ionised form only. The adsorption coefficient (Koc) of the test material has been determined to be <17.8, logKoc <1.25. This low value is considered consistent with the low partition coefficient.
This value indicates a low potential for the substance to adsorb to soil/sediment and suggests high mobility in the environment.
As the screening study indicated a low potential for adsorption, no higher level testing for this endpoint has been proposed by the registrant
