Cobalt in zebra mussels from the Donau
Significant differences between the sampling sites
Cobalt is an essential element for many animals. High cobalt levels, however, may be toxic. Many organisms, like zebra mussels, are capable of accumulating cobalt.
Cobalt concentrations in zebra mussels from the river Danube gradually increase downstream. Highest concentrations are detected at Jochenstein at the German-Austrian border. This sampling site is located downstream of the Inn-confluence and is strongly influenced by navigation.
