Indicator Assessment Oxygen consuming substances in rivers (CSI 019) - Assessment published Oct 2012
Concentrations of BOD and total ammonium have decreased in European rivers in the period 1992 to 2010 (Fig. 1), mainly due to general improvement in wastewater treatment. See also WISE interactive maps: Mean annual BOD in rivers and Mean annual Total Ammonium in rivers

Indicator Assessment Oxygen consuming substances in rivers (CSI 019) - Assessment DRAFT created Apr 2012
Concentrations of BOD and total ammonium have decreased in European rivers in the period 1992 to 2009 (Fig. 1), mainly due to general improvement in wastewater treatment. See also WISE interactive maps:   Mean annual BOD in rivers and Mean annual Total Ammonium in rivers

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 Total ammonium concentrations in rivers between 1992 and 2009 in different geographical 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 specification). The number of river monitoring stations included in the analysis per geographic region is noted in brackets.

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.
