Umwelt-Indikator

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

A graph shows the change in the concentration of total nitrogen in all major rivers that discharge into the North and Baltic Sea in Germany and indicates the target value of 2.8 or 2.6 mg/L total nitrogen for North and Baltic Sea, respectively. The concentration value is calculated as the 5-year moving average of the flow-weighted mean concentration of all major rivers in milligrams total nitrogen per litre (mg/L).

To achieve the objectives for the protection of the marine environment, Germany has committed to achieve target values for total nitrogen at the limnic-marine transition points.For the flow-weighted 5-year moving average of all rivers, these target values are achieved for the North Sea, but are still exceeded for the Baltic Sea.Some of the North and Baltic Sea tributaries still have very high conc... read more
