No data are put forward as this endpoint is not relevant for lead , and metals in general
Annex VIII states that "Further degradation testing shall be considered
if the chemical safety assessment according to Annex I indicates the
need to investigate further the degradation of the substance. The choice
of the appropriate test(s) will depend on the results of the chemical
Waiving of the need for data for this endpoint in the aquatic
compartment (water and sediment) may be considered if “The substance is
highly insoluble in water”, or if “The substance is readily
biodegradable” (ECHA 2008, Chapter R.7B – Endpoint Specific Guidance).
However, 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 is an irrelevant process:
biotic processes may alter the speciation form of an element, but it
will not eliminate the element from the aquatic compartment by
degradation or transformation. This elemental-based assessment (pooling
all speciation forms together) can be considered as a worst-case
assumption for the chemical assessment.
