Description of key information
Additional information
Sugar factory lime (SFL) is primarily composed of inorganic substances (the major constituent is calcium carbonate, along with silicon dioxide and a small amount of other inorganic salts) and the remainder is composed of organic plant material which is naturally present in the environment.
Since many of the components of SFL are naturally occurring in the environment, aquatic species are likely to be exposed to these substances on a continual basis and hence their intracellular and extra-cellular concentrations are actively regulated. Therefore, bioaccumulation is not expected.
Studies in soil and sediment cannot be performed as irrespective of the method selected to monitor the test material, analytical difficulties could arise from the addition of SFL to soil and sediment 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 and sediment. 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 or sediment themselves.
Since SFL is primarily composed of inorganic substances, the organic carbon content of the soils or sediment 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.
Furthermore, since SFL is primarily composed of inorganic substances it does not undergo biodegradation i.e. microbial degradation to carbon dioxide and water. The inorganic portion will be degraded in the environment by means other than biodegradation. The remainder of SFL is composed of organic plant material which is naturally present in the environment. Although SFL itself is not readily biodegradable the organic portion will undergo ultimate degradation in surface water. The fact that the organic plant material is naturally occurring and non-toxic to the environment means that its presence and degradation would not lead to any disruption of the natural environmental processes.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
