Additional information
BOD5 data from Austria, Bulgaria, Czech Rep., Denmark, France, Hungary, Luxembourg, Slovak Rep. and Slovenia. BOD7 data from Estonia. Ammonium data from Austria, Bulgaria, Denmark, Estonia, Finland, France, Germany, Hungary, Latvia, Luxembourg, Poland, Slovak Rep., Slovenia, Sweden and the UK. 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).
