Additional information

There are no tests available on terrestrial toxicity for silicic acid, lithium salt. However, direct emissions from soluble silicates to the terrestrial compartment are considered negligible. Furthermore, since silicates are 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.

A single study is available on honeybees by Richards (2006), which was conducted with a related substance, potassium silicate. In this study the 48 h LD0 and L50 were determined to be 25 ug and > 25 ug active matter per animal, respectively.
