Description of key information

Key value for chemical safety assessment

Additional information

There are no tests availbale on toxicity to birds. However, direct emissions from soluble silicates to the terrestrial compartment are considered negligible. Since silicates are furthermore natural components of soil minerals, such tests would be of limited value. SiO2 makes up 59% of the earth's crust and similar percentages are present in many sediments and soils. The contribution of anthropogenic inputs to the occurrence in the various compartments will be negligible compared to the concentrations contributed to by the natural silica flux.
