Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

NOEC (growth, 96 h): 5000 mg/kg soil dw.

NOEC (reproduction, 96 h): 5000 mg/kg soil dw.

Additional information

There is only data available for soil macroorganisms except arthropods. Here, no inhibitory toxic effects occurred on the growth and reproduction of C. elegans up to nominal concentrations of 5000 mg/kg sediment dry weight (dw) with the read-across substance Silicic acid, aluminum magnesium sodium salt (CAS 12040-43-6, SMAS). Thus, a NOEC of 5000 mg/kg sediment dw based on nominal concentrations was determined. Between 200 and 3200 mg/kg sediment dw, significant stimulatory effects on reproduction occurred. 

The performance of studies investigating further terrestrial toxicity of amorphous aluminium sodium silicates was waived due to the natural occurrence and abundance of SiO2, silicates and aluminium as minerals in the soil.
