Adsorption / desorption

According to column 2 of Annex VIII, this study does not need to be conducted since Calcium iodate has low octanol water partition co-efficient value of -5.28. Also, the Soil Adsorption Coefficient estimated using the KOCWIN v2.00 indicate that the Log Koc value in soil environment would be 1.7831. Therefore this study was considered for waiver.

Henry's Law constant:

Henry's Law states that at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid. The Henry's Law Constant of calcium iodate which is a solid at 25°C is 0.00000000000000004233 (4.233E-017)Pa m³/mol.
