Description of key information
No studies on SFL are available.
The key study was conducted on an analogous substance and assessed the acute toxicity of calcium carbonate (nano) to Oncorhynchus mykiss (rainbow trout). The 96 h EC50 was >100% v/v saturated solution and the NOEC was 100% v/v saturated solution.
The result from this study demonstrates that calcium carbonate is not acutely toxic to fish at the limit of its solubility in water and can be read across to SFL.
Key value for chemical safety assessment
Additional information
Rationale for read across:
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 (including calcium salts) and the remainder is composed of organic plant material. None of the components of SFL carry a classification for physical chemical properties or the environment and therefore SFL is not classified as hazardous to the environment. Since the major component of SFL is calcium carbonate, it can therefore be assumed that the properties of SFL will be governed by those of calcium carbonate. It is therefore considered appropriate for this data to be used for read-across purposes and any further testing would be scientifically unjustified.
The key study [Priestly (2010a)] was performed to OECD Guideline 203 and in accordance with GLP. The study assessed the acute toxicity of calcium carbonate (nano) to Oncorhynchus mykiss (rainbow trout) in a limit test. No mortalities or adverse effects were noted at the concentration tested. Hence, the 96 h LC50 for calcium carbonate (nano) was found to be >100% v/v saturated solution and the NOEC was 100% v/v saturated solution.
The concentration of calcium carbonate (nano) that might cause acute toxicity is therefore greater than the maximum solubility of calcium carbonate in water. Since this study is applicable to SFL, it is expected that SFL would also not be acutely toxic to fish.
