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.
