Additional information

Experimental data on the adsorption/desorption of magnesium hydrogen orthophosphate (CAS 7757-86-0) is not available. Testing the adsorption/desorption behaviour according to OECD Guideline 121 is not feasible as the test method is not validated for inorganic substances. A batch equilibrium study according to OECD Guideline 106 was not conducted since analysis of the test material may not be possible due to interference from the soil extracts that may leach into the aqueous media during the test. This would prevent quantification of the test material.
