Trends in mean winter orthophosphate concentrations in the Atlantic, Baltic Sea, Greater North Sea, Skagerrak and part of the Mediterranean in 1985–2005
Numbers in parentheses indicate number of stations included in the analysis for each country
Observed changes in winter orthophosphate (PO4) concentrations, 1985–2010
The map shows stations with a statistically significant decrease (green), increase (red) or no trend (yellow) in winter ortophosphate concentrationswithin the period 1985-2010. Selected stations must have at least data in the period from 2007 to present and at least 5 years data in all.
Trends in winter mean orthophosphate concentrations in European seas
The map shows the trends per station in orthophosphate (PO4) concentrations in the upper 10 m of the water column, observed during winter of the years 1990-2017.
Phosphorus in European rivers, 1994-96
Annual average phosphorus concentration in rivers
Annual average river orthophosphate concentration (mg/l as PO4-P) in 2008, by river basin district
The map shows the annual average river orthophosphate concentration by river basin district (mg/l as PO4-P) in 2008
Average pollution concentrations for European rivers
Concentrations of nitrate and orthophosphate in rivers and total phosphorus in lakes in the period 1992–2007
Total number of stations in parenthesis. Concentrations are expressed as weighted means of annual mean concentrations for rivers and lakes. Only stations with time series of seven years or more are included.
Concentrations of total ammonium, biochemical oxygen demand, nitrate and orthophosphate in European rivers between 1992 and 2002
Concentrations are average of the annual average concentrations per year
Average concentration of orthophosphorus in European rivers
Nutrient trends in European water bodies
The data series are calculated as the average of annual mean concentrations for groundwater bodies/river stations/lake stations in Europe. Only complete series after inter/extrapolation are included (see indicator specification). The number of groundwater bodies/river stations/lake stations included per country is given in the notes below the individual substance charts.
