Description of key information

Additional information

Concerning aquatic short-term toxicity effects, tests for representatives of each trophic level (fish, Daphnia, algae) are available. The test results with structurally related compounds presented hereby confirmed that the toxicity profile of silicic acid, aluminium salt for aquatic species is of low concern. The most sensitive species were the algae. However, the EC50 values of all species are above 410 mg/L, which is far higher than the solubility of the substance in water.

Long-term toxicity data are available for daphnids and algae in tests with structurally related compounds. The most sensitive species were algae with an EC10 value of 41 mg/L (growth rate). A study on chronic toxicity to fish has not been conducted due to the low acute toxicity and animal welfare reasons.
