Additional information

The three tests on acute toxicity to the three trofic level for aquatic toxicity have been performed (Tediosi, 2013) on the similar substance Reaction mass of dipotassium phosphonate and Phosphonic acid, potassium salt (1:1) in water solution. No concern for aquatic acute toxicity is raised from the three acute tests. Tests results are fully applicable also to calcium dihydrogenphosphite because salts dissociate in aqueous media and the phosphite anion is expected to be the driver for the effects.
