Description of key information

Zinc is an essential element which is actively regulated by organisms, so bioconcentration/bioaccumulation is not considered relevant.

Key value for chemical safety assessment

Additional information

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.
