According to the guidance given in Annex VII
of REACH legislation and Chapter R.7B (Endpoint Specific Guidance) of
the ECHA REACH Guidance Document, (2008), the requirements for “Ready
biodegradability” can be waived if the substance is inorganic (e.g.,
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 safety assessment." Waiving of the need for data
for this environmental endpoint 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 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.
