Description of key information

Simple inorganic salts with high aqueous solubility will exist in a dissociated form in an aqueous solution. Such a substance has a low potential for adsorption. In addition a screening study (OECD 121) could not be conducted as it is technically not feasible to perform and QSARs are not suitable for such substances.

Nitrate is not bound to the soil and will follow water movements. Nitrate can therefore leach when the soil receives more water than it can take up. This happens (in) mainly in the late autumn, winter, and early spring. There exist a lot of studies on the environmental impact of NO3and NH4+/NH3.

Based on information available, it can be concluded that nitric acid, ammonium calcium salt, will completely dissociate into ions in water and thus has a low potential for adsorption. In addition, volatilization is also unlikely due to the properties of the substance
