Applicant's summary and conclusion
- Executive summary:
In an adsorption desorption study using the batch equilibrium method, Koc values have been determined for ZrOCl2 in two different soils:
Soil A (pH = 5.45) = 18868 at 20 °C
Soil B (pH = 8.3) = 89286 at 20 °C
Absorption to solid soil phase is expected for zirconium and water soluble zirconium salts, respectively. Water soluble zirconium salts like zirconium tetrachloride, zirconium diacetate or zirconium dichloride oxide once in aqueous media dissociate very quickly at pH values of 4 to 9.5 forming the conjugate acid and hydrated forms of the insoluble ZrO2 (the most stable form of zirconium in water) (Daunderer, M.; Lehrbuch Klinische Toxikologie, 89. Erg. Lfg.; 11/94).
Due to the similar dissociation pattern it is concluded, that read across to other soluble zirconium salts is valid for the assessment of ecotoxicological endpoints of zirconium tetranitrate.
