As mentioned previously, in the case of the current substance (i.e., Pb-salts), the chemical safety assessment will be based on elemental metal concentrations, regardless of their (pH-dependent) speciation in the environment. Hence, as the assessment is based on the element concentration (i.e., Pb), physicochemical processes like phototransformation and hydrolysis are not relevant. Formation of different Pb-hydroxides may occur, but the chemical assessment will not make any differentiation among the different Pb-species (pooling of different speciation forms). This elemental-based assessment (pooling all speciation forms together) can be considered as a worst-case assumption for the chemical assessment. In general, (abiotic) degradation is an irrelevant process for inorganic substances that are assessed on an elemental basis.
