Indicator: Eutrophication of the North Sea/Baltic Sea by nitrogen

A graph shows the change in concentration of total nitrogen in all the main rivers which enter the North Sea and Baltic Sea in Germany. A distinction is made between the North Sea and the Baltic Sea. The concentration value is given as the moving average of the flows of the past 5 years in milligrams per litre.

To achieve the objectives for the protection of the marine environment, Germany has committed to comply with maximum concentrations of nitrogen at estuaries.On average for all rivers, these target concentrations are already met for the North Sea, but still exceeded for the Baltic Sea.Some of the North Sea and Baltic Sea tributaries still have very high concentrations.In order to fulfil the objecti... read more
