PBT asessments are not relevant to metals.
Bioaccumulation: This is not relevant for essential elements:
metal-generic information, available from 2009 -2011 EU guidance
documents, clearly indicates that a classic BCF approach is not
considered relevant. The EU CLP and EU EQS guidance (2009-2011) both
indicate that due to homeostatic regulation, the “bioaccumulative”
criterion is not applicable to essential metals.
The copper Risk Assessment Report (2008) and REACH Chemical Safety
Report (2010) have provided detailed information on (1) the essentiality
of copper; (2) the homeostatic control of copper; (3) the mechanisms of
action of copper-ions; (4) the comparison between copper toxicity from
dietary versus waterborne exposures.
The data clearly demonstrate that:
The assessment therefore demonstrates that the hazard criterion
“bioaccumulative” is not relevant for copper. More details : see
Persistence: Copper is an element, and as such the criterion
“persistence” is not relevant for the metal and its inorganic compounds
Considering the above, copper is neither PBT nor vPvB.
