Nitrate and phosphorus concentrations in selected WCE freshwater bodies

Finland (6 stations on 6 lakes), Germany (5 stations on 5 lakes), Hungary (15 stations on 6 lakes), Latvia (1 station on 1 lake) and Slovenia (4 stations on 2 lakes). Total phosphorus data from Austria (5 stations on 5 lakes), Denmark (19 stations on 19 lakes), Estonia (4 stations on 1 lake), Finland (11 stations on 11 lakes), Germany (5 stations on 5 lakes), Hungary (11 stations on 2 lakes), Latvia (1 station on 1 lake), Sweden (3 stations on 3 lakes) and Slovenia (4 stations on 2 lakes). Groundwater bodies: 147 groundwater bodies with data from Austria, Bulgaria, Denmark, Estonia, Finland, Germany, Lithuania, the Netherlands, Norway, Portugal, Slovakia, Slovenia and the United Kingdom. Rivers: data from Austria, Bulgaria, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Latvia, Lithuania, Poland, Slovakia, Slovenia, Sweden and the United Kingdom. Concentrations are expressed as median of annual average concentrations for groundwater, rivers and lakes. Data are from representative river and lake stations. Stations that have no designation of type are assumed to be representative and are included in the analysis.
