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.

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.

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

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.
