More information


Additional information:
The geographical coverage is the 38 EEA member countries including Kosovo under UNSC Resolution 1244/99.
The current BOD level per river monitoring site is calculated as the average of available annual mean concentrations for the years 2018-2020. BOD is given as mg oxygen per litre (mg O2/l).

The river monitoring sites are assigned to different BOD classes to visualise the distribution of data in the dataset. The number of river monitoring sites per country is given in parenthesis.

Sweden, with BOD data for only two sites, is excluded from the chart since the sites may not be representative.
