Total ammonium concentrations in rivers between 1992 and 2005 in different regions of Europe
Northern Europe: Denmark (26), Finland (27), Norway (10), Sweden (79). Western Europe: Austria (91), Belgium (10), France (181), Germany (111), Luxembourg (3), United Kingdom (14). Eastern Europe: Estonia (44), Hungary (89), Latvia (36), Lithuania (23), Poland (76), Slovenia (21). Southern Europe: Greece (14), Italy (66), Spain (124). Southeastern Europe: Bulgaria (88), Macedonia FYR (9). 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 between 1992 and 2005 (Northern, Western and Eastern Europe), between 1999 and 2005 (Southeastern Europe) and between 2000 and 2005 (Southern Europe) have been calculated using only stations that have recorded concentrations for each year included in the time series, except one year missing concentrations for Denmark (2005), Greece (2005) and Luxembourg (2003).
