Abiotic degradation

The term ‘Hydrolysis’ refers to the “Decomposition or degradation of a chemical by reaction with water”, and this as a function of pH (i.e., abiotic degradation). In the case of metals like bismuth the chemical safety assessment is generally based on total elemental metal concentrations, regardless of their (pH-dependent) speciation in the environment. Therefore, physicochemical processes like degradation or transformation by reaction with water are judged not relevant for the bismuth component of bismuth subnitrate.

Biotic degradation

The concept of biotic degradation does not apply to inorganic substances like bismuth subnitrate.
