Zinc in livers of bream from the Donau
Relatively high zinc levels at all three sampling sites
Zinc is an essential element. In higher animals the zinc body concentrations are regulated with the liver as central organ of regulation and storage.
Zinc in bream livers from the river Danube was relatively high. Since monitoring started in 2004, concentrations varied between years without clear trends over time or continuous differences between sampling sites.
Bioindicator in rivers and lakes
