GIS Map Application Total phosphorus in lakes
The map shows the mean annual concentrations of total phosphorus (TP) as mg/L TP in European lakes and reservoirs measured at Eionet-Water Lake monitoring stations during 2011. Total phosphorus includes all phosphorus components in lake water: phosphate dissolved organic phosphorus and particulate phosphorus in algal and bacterial cells, as well as in mineral particles (e.g. clay). For most countries the concentration values are based on measurements over the whole year, but for some countries the annual mean actually represents only the growing season (due to ice cover in winter).

Figure Phosphorus concentrations in lakes (total phosphorus) between 1992 and 2011 in different geographical regions of Europe.
The data series per region are calculated as the average of the annual mean concentrations for river monitoring stations in the region. Only complete series after inter/extrapolation are included (see indicator specification). There were no stations with complete series after inter/extrapolation in the South and Southeast regions. The number of lake monitoring stations included per geographical region is given in parentheses

Figure Phosphorus concentrations in rivers (orthophosphate) between 1992 and 2011 in different sea regions of Europe
The sea region data series are calculated as the average of annual mean concentrations for river monitoring stations in each sea region. The data thus represents rivers or river basins draining into that particular sea. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations per sea region is given in parentheses.

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment DRAFT created Sep 2013
Average nitrate concentrations in European groundwaters increased from 1992 to 1998, but have declined again since 2005. On average, the nitrate concentration in European rivers declined by 0.5 mg N/l over the period 1992 to 2011 (20% relative to the average concentration), reflecting the effect of measures to reduce agricultural inputs of nitrate as well as improvement in wastewater treatment. Average orthophosphate concentrations in European rivers have decreased markedly over the last two decades- On average concentrations declined by 0.08 mg P/l between 1992 and 2011 (72% decrease relative to the average concentration). Also average lake phosphorus concentration decreased over the period 1992-2011 (on average by 0.008 mg P/l, or 27% relative to the average concentration). The decrease in phosphorus concentrations reflects both improvement in wastewater treatment and reduction in phosphorus in detergents. Overall, reductions in the levels of freshwater nutrients over the last two decades primarily reflect improvements in wastewater treatment. Emissions from agriculture continue to be a significant source.

Figure D source code Changes in Phosphorus balance and GVA of agriculture in Europe 2000–2008 (EU16 + Norway)
The chart displays changes in emission of phosphorus from agriculture (expressed as phosphorus balance, P-balance) , and the economic output of agriculture and related services and activities expressed as the gross value added (GVA) in Europe between 2000 and 2008. Changes are expressed in %, where values for 2000=100 %.

Figure Trend in median total ammonium, total phosphorus and nitrate concentration of river water bodies, grouped by ecological status/potential class
Concentrations are expressed as a median of annual mean concentrations. Up to three-year gaps of missing values have been interpolated or extrapolated. Only complete series with no missing values after this interpolation/extrapolation are included. The number of time series/river stations is shown in parentheses. The trend for 1992 to 2010 for each of the ecological quality classes has been linearly extended to 2027 — or when the concentration level becomes negative.

Figure Phosphorus concentrations in rivers (orthophosphate) between 1992 and 2010 in different sea regions of Europe
The sea region data series are calculated as the average of annual mean data from river monitoring stations in each sea region. The data thus represents rivers or river basins draining into that particular sea. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations per sea region is given in parentheses.
