Figure Change in the severity of river flow droughts in France 1960-2000
Located in Data and maps Maps and graphs
Figure Trends in concentration of cadmium and mercury at river stations included in the EU Exchange of Information Decision
In less polluted areas in, for example, Nordic countries, concentrations of cadmium and mercury are only 10 and 1 % of these values

Figure WISE Large rivers and large lakes
In order to have a visually uninterrupted hydrographic network WISE Large rivers and large lakes should be used in combination with Transitional waters that resides along with the River basin district data.

Figure BOD5 concentrations in rivers between 1992 and 2008 in different sea regions of Europe
Geographical coverage: Atlantic Ocean, Baltic Sea, Black Sea, Mediterranean Sea and the North Sea.

Figure Total area-specific nitrogen and phosphorus load (before retention) by sources and nitrogen surplus in large river catchments using the Moneris model.
Sorted by increasing nitrogen surplus

Figure Annual average phosphorus concentration in rivers

Figure D source code Biochemical Oxygen Demand (BOD5) and total ammonium concentrations in rivers between 1992 and 2008
Concentrations are expressed as the average of annual mean concentrations. Up to 3-year gaps of missing values have been interpolated or extrapolated. Only complete series with no missing values after this interpolation/extrapolation are included. Number of river monitoring stations included in analysis per country is noted in brackets. BOD7 data has been recalculated into BOD5 data.

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment published Dec 2010
Average nitrate concentrations in European groundwaters increased from 1992 to 1998, and have remained relatively constant since then. The average nitrate concentration in European rivers decreased by approximately 9 % between 1992 and 2008 (from 2.4 to 2.2 mg/l N), reflecting the effect of measures to reduce agricultural inputs of nitrate. Average orthophosphate concentrations in European rivers have decreased markedly over the last two decades, being almost halved between 1992 and 2008 (47 % decrease). Also average lake phosphorus concentration decreased over the period 1992-2008 (by 26%), the major part of the decrease occurring in the first half of the period. The decrease in phosphorus concentrations reflect 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.
