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.
