Additional information

Soil adsorption/ desorption studies with SFL are not possible.

Irrespective of the method selected to monitor the test material, analytical difficulties could arise from the addition of SFL to soil due to its high concentration of calcium ions. A significant contribution of dissolved calcium would be expected in all samples due to the presence of calcium salts as a naturally occurring mineral fraction in soils. Therefore, it would not be possible to analytically distinguish between contributions to the analysed solution calcium concentration originating from the test material and that originating from the soils themselves.

Since SFL is primarily composed of inorganic substances, the organic carbon content of the soils is not anticipated to play a significant role in the mobility of inorganic salts and therefore the actual test endpoint, that of an organic carbon normalised adsorption coefficient (Koc) is probably not actually valid/ relevant for this type of substance. The determination of a Koc value is also not applicable to a UVCB substance.
