Additional information

BOD5 data from Austria, Bulgaria, Czech Republic, France, Hungary, Slovakia, Slovenia and United Kingdom. BOD7 data from Estonia, Latvia (1996-2001) and Lithuania (1996-2005). BOD7 data were recalculated into BOD5 data. Total ammonium data from Austria, Belgium, Bulgaria, Estonia, Finland, France, Germany, Hungary, Latvia, Lithuania, Norway, Poland, Slovenia, Sweden and United Kingdom. Concentrations are expressed as median of annual average concentrations. Data are from representative river stations. Stations that have no designation of type are assumed to be representative and are included in the analysis. Consistent time series trends have been calculated using only stations that have recorded concentrations for each year included in the time series (see Methodology section for further details).
