Description of key information

For an inorganic substance for which the chemical assessment is based on the elemental concentration, biotic degradation is an irrelevant process.

Key value for chemical safety assessment

Additional information

For an inorganic substance for which the chemical assessment is based on the elemental concentration (i.e. pooling all inorganic speciation forms together), biotic degradation in the environment is an irrelevant process. Biotic processes may alter the speciation form of an element, but it will not eliminate the element from the environment by degradation or transformation processes. This elemental-based assessment (pooling all speciation forms together) can be considered as a worst-case assumption for the chemical assessment.
