Phototransformation is not a relevant endpoint for inorganic lead
As mentioned previously, in the case of the current substance (i.e.,
Pb-salt ), 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.
