Description of key information
No long term study was performed with the substance. A read-across was made with all the soluble aluminium salts: AlCl3, AlNO3 and AlSO4 on Pimephales promelas
Key value for chemical safety assessment

Additional information
The substance is a ceramic . In contact with water the substance is hardening within minutes integrating most of the soluble fraction into the solid formed. Nevertheless to assess the toxicity of the substance, the worst case scenario for solubility has been applied:
In the absence of organic matter, Al3+ is the predominant aluminium species at low pH (less than 5.5). As pH increases above 5.5, aluminium-hydroxide complexes formed by hydrolysis become increasingly important and dominate aqueous aluminium speciation . Al3+, depending on the composition of the medium and pH, may form Al(OH)3 or AlCl or AlNO3 or AlSO4. According to the long term solubility calculation:
- At long term, if we consider the substance as a 100% CaAl2O4component:
o 1mg of ground substance if completely dissolved will provide 0.341mg of total Aluminium (34.1%) until Al(OH)3saturation.
Knowing that maximum CaAl2O4content is 70% , the ratio between substance and Aluminium equivalent Al(OH)3 is 0.7 x 0.341 = 0,238. or 1g of Aluminium equivalent Al(OH)3 is 4.2g of substance.
A read-across was made with all relevant soluble aluminium salts and an assessement factor of 4.2 is applied for the calculation of the substance long term NOEC .A long-term reliable chronic toxicity studies with AlCl3 to Pimephales promelas is identified as acceptable from the published literature. The Lowest NOEC (7 days) is 15 mg/L
Other two supporting studies on aluminium nitrate and aluminium sulfate may be used to assess the low toxicity of the soluble fraction of the substance.
Hence the calculated NOEC for the substance is 63 mg/L
