Marine environment

Our marine environment is impacted in many ways by human activities. One of our core tasks is to assess the effects of environmental pollution on fish as a compartment of the marine environment and as an important natural resource. To this end, we investigate which potential pollutants are taken up by fish in which concentrations, how these substances accumulate in the fish, how they affect the fish and which degradation products are formed in the organism, always with a view to potential hazards for consumers. In addition to various inorganic and organic pollutants, the risk assessment of dumped munitions is one of our main research areas.
