Additional information

No tests are available on silicic acid, lithium salt. Data considered here is read-across from potassium silicate based on an analogue-approach. In a GLP guideline study with honey bees by Richards (2006), following EPA OPPTS 850.3020 (Honey Bee Acute Contact Toxicity), for a potassium silicate solution (29.1 wt %) the 48 h LD0 and L50 were determined to be 25 ug and > 25 ug active matter per animal, respectively.
