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.These target concentrations in the North Sea and Baltic Sea are only slightly exceeded on average by all rivers, but some rivers still have very high concentrations.In order to fulfil the objectives, it is necessary that each river achieves th... read more
