Figure D source code Biochemical Oxygen Demand (BOD5) and total ammonium concentrations in rivers between 1992 and 2008
Concentrations are expressed as the average of annual mean concentrations. Up to 3-year gaps of missing values have been interpolated or extrapolated. Only complete series with no missing values after this interpolation/extrapolation are included. Number of river monitoring stations included in analysis per country is noted in brackets. BOD7 data has been recalculated into BOD5 data.

Figure Biochemical Oxygen Demand (BOD5) and total ammonium concentrations in rivers between 1992 and 2009
Concentrations are expressed as the average of annual mean concentrations. Up to 3-year gaps of missing values have been interpolated or extrapolated. Only complete series with no missing values after this interpolation/extrapolation are included. The number of river monitoring stations included in the analysis is noted in brackets. BOD7 data has been recalculated into BOD5 data.

Figure Biochemical Oxygen Demand (BOD5) and total ammonium concentrations in rivers between 1992 and 2010
Concentrations are expressed as annual mean concentrations. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations included per country is given in metadata (see downloads and more info). BOD7 data has been recalculated into BOD5 data.

Figure Biochemical Oxygen Demand (BOD5) and total ammonium concentrations in rivers between 1992 and 2011
Concentrations are expressed as annual mean concentrations. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations included per country is given in metadata (see downloads and more info). BOD7 data has been recalculated into BOD5 data. If data on total ammonium are not available, data on ammonium are included into the data series.

Figure BOD5 concentrations in rivers between 1992 and 2011 draining to different sea regions of Europe
The sea region data series are calculated as the average of annual mean data from river monitoring stations in each sea region. The data thus represents rivers or river basins draining into that particular sea. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations included per sea region is given in parentheses. There were no stations with consistent data series on BOD7 in rivers draining to the Arctic Ocean. BOD7 data has been recalculated into BOD5 data.
