Figure Trend in total ammonium (NH4) concentrations and BOD5 in selected WCE rivers (1992-2004)
Numbers of river monitoring stations in brackets
Located in Data and maps Maps and graphs
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 Annual average concentrations of ammonium N measurements at Bimmen / Lobith (Rhine)
Located in Data and maps Maps and graphs
Figure Concentrations of total ammonium, BOD, nitrate, and orthophos-phates in European rivers between 1992 and 2001
Located in Data and maps Maps and graphs
Figure Average pollution concentrations for European rivers
Located in Data and maps Maps and graphs
Figure Total ammonium concentrations in rivers between 1992 and 2008 in different sea regions of Europe
Geographical coverage: Atlantic Ocean, Baltic Sea, Black Sea, Mediterranean Sea and the North Sea.

Figure Total ammonium concentrations in rivers between 1992 and 2009 draining to different sea regions of Europe
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 (see indicator specificatios). The number of river monitoring stations included in the analysis per sea region is noted in brackets.

Figure Development of mean plot concentration in open-field measurements of sulphate (SO4, 285 plots), nitrate (NO3, 294 plots), and ammonium (NH4, 294 plots); 1996-2001
Located in Data and maps Maps and graphs
Figure Concentrations of total ammonium, biochemical oxygen demand, nitrate and orthophosphate in European rivers between 1992 and 2002
Concentrations are average of the annual average concentrations per year
Located in Data and maps Maps and graphs
Figure Total ammonium concentrations in rivers between 1992 and 2011 in different geographical regions of Europe
The data series per region are calculated as the average of the annual mean for river monitoring stations in the region. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations included per geographical region is given in parentheses. If data on total ammonium are not available, data on ammonium are included into the data series.
