Figure Phosphorus concentrations in lakes (total phosphorus) between 1992 and 2010 in different geographical regions of Europe.
The data series per region are calculated as the average of the annual mean 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 transitional, coastal and marine waters (CSI 021) - Assessment published Mar 2013
In 2010, the highest concentrations of oxidized nitrogen were found in the Baltic Sea, in the Gulf of Riga and Kiel Bay, and in Belgian, Dutch and German coastal waters in the Greater North Sea. Reported stations in the Northern Spanish and Croatian coastal waters also showed high concentration levels. The highest orthophosphate concentrations were found in the Baltic Sea, in the Gulf of Riga and Kiel Bay, and in Irish, Belgian, Dutch and German coastal waters in the Greater North Sea. Coastal stations along Northern Spain and Southern France also showed high concentration levels. Between 1985 and 2010, overall nutrient concentrations have been either stable or decreasing in stations reported to the EEA in the Greater North Sea, Celtic Seas and in the Baltic Sea. However, this decrease has been more pronounced for nitrogen. Assessments for the overall Mediterranean and Black Sea regions were not possible, data only being available for stations in France and Croatia.  For oxidized nitrogen concentrations, 14% of all the reported stations showed decreasing trends, whereas only 2% showed increasing trends. Decreases were most evident in the Baltic Sea (coastal waters of Germany, Denmark, Sweden and Finland, and open waters) and in southern part of the coast of the Greater North Sea. Increasing trends were mainly found in Croatian coastal stations.  For orthophosphate concentrations, 10% of all the reported stations showed a decrease. This was most evident in coastal and open water stations in the Greater North Sea, and in coastal stations in the Baltic Sea. Increasing orthophosphate trends, observed in 6% of the reported stations, were mainly detected in Irish, Danish and Finnish coastal waters (Gulf of Finland and Gulf of Bothnia) and in open waters of the Baltic Proper.

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment published Oct 2012
Average nitrate concentrations in European groundwaters increased from 1992 to 1998, but have declined again since 2004. The average nitrate concentration in European rivers decreased by approximately 11% between 1992 and 2010 (from 2.5 to 2.2 mg/l N), 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, being more than halved between 1992 and 2010 (54% decrease). Also average lake phosphorus concentration decreased over the period 1992-2010 (by 31%), the major part of the decrease occurring in the beginning of the period, but is still ongoing. 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 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.

GIS Map Application WISE SoE: Orthophosphate in rivers
This map shows the mean annual concentrations of phosphate (orthophosphate, OP) as mg/L PO4-P measured at Eionet-Water River monitoring stations during 2011. All data are annual means. For most countries these are based on measurements over the whole year, whereas some countries have samples only from the growing season (due to ice cover in winter). The purpose of the map is to provide an overview of the annual concentrations of the orthophosphates in rivers across Europe and to enable viewer to make comparisons of the values in European countries, River basin districts or in individual monitoring sites. High or increased (compared to reference condition) concentration of Phosphate represents a risk to normal functioning of River ecosystems, causing eutrophication with potentially excessive growth of benthic algae or other aquatic vegetation, oxygen deficiency in the bottom substrate and reduced biodiversity.

Figure 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.
