Biodegradation as used for organic substances does not apply to
inorganic substances such as copper and its compounds, but attenuation
of the toxicity is observed.
This was recognized in the Guidance to Regulation (EC) No
1272/2008 Classification, Labelling and Packaging of substances and
mixtures (metal annex): “Environmental transformation of one species of
a metal to another species of the same does not constitute degradation
as applied to organic compounds and may increase or decrease the
availability and bioavailability of the toxic species. However as a
result of naturally occurring geochemical processes metal ions can
partition from the water column. Data on water column residence time,
the processes involved at the water – sediment interface (i. e.
deposition and re-mobilisation) are fairly extensive, but have not been
integrated into a meaningful database. Nevertheless, using the
principles and assumptions discussed above in Section IV.1, it may be
possible to incorporate this approach into classification. "

pathways" and "addional information on environmental fate".
