Residue from treatment of calcined zinc ore concentrates with antimony trioxide, zinc dust, lead oxide and copper sulfate. Consists primarily of zinc and a composite of metallics: cobalt, copper and lead.
Zinc is an essential element which is actively regulated by organisms, so bioconcentration/bioaccumulation is not considered relevant.
Bioaccumulation is not considered relevant for essential elements
because of the general presence of homeostatic control mechanisms. the
data from a field food chain transfer study indicate that
bioconcentration of zinc is indeed very low. It is in all cases also
lower in contaminated soil, as compared to control soil.
