Description of key information
The acute toxicity of sugar factory lime (SFL) to Daphnia magna has been investigated in a GLP study performed in accordance with OECD Guideline 202. The 48 h EC50 was >100 mg/L based on the water accommodated fraction.
The results from this study demonstrate that SFL is not acutely toxic to aquatic invertebrates.
Key value for chemical safety assessment
Additional information
The key study [Degussa (2007c)] was performed to OECD Guideline 202 and in accordance with GLP and was therefore assigned a reliability of 1. The study assessed the acute toxicity of Sugar Factory Lime (SFL) to Daphnia magna in a limit test. Since the test substance is a multi-component substance and is poorly soluble in water, the test was performed with the water-accommodated fraction (WAF) of 100 mg SFL/L medium. No toxic effects were seen at this test concentration. Hence, the 48 h EC50 was >100 mg/L.
The study for SFL is supported by an acute toxicity study to Daphnia magna performed with calcium carbonate (nano) [Priestly (2010b)]. The study assessed the acute toxicity of calcium carbonate (nano) to Daphnia magna in a limit test. No toxic effects were seen when a 100% v/v saturated solution of calcium carbonate was tested. Hence, the 48 h EC50 was >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.
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).
