    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).
