Effects of air pollution on European ecosystems
Past and future exposure of European freshwater and terrestrial habitats to acidifying and eutrophying air pollutants
10 messages for 2010 — freshwater ecosystems
Freshwater ecosystems in Europe are rich in biodiversity but at risk. They provide essential ecosystem services to humans, such as cleaning water, preventing floods, producing food, providing energy and regulating freshwater resources...

SOLUTIONS project output simulating the impact of chemical mixtures on a potentially affected fraction of species (msPAF) and highlighting regions where there could be significant chemical pollution pressure on freshwater species
This map shows a mixture toxicity metric called multi-substance Potentially Affected Fraction of species (msPAF). For individual substances, the Potentially Affected Fraction of species (PAF) is derived from the results from laboratory toxicity tests, as the fraction of the tested species that would show effects if a laboratory test would be performed with a given concentration of the chemical. To this end, the results from laboratory tests have been converted beforehand into a species sensitivity distribution (SSD). The individual PAFs are then combined into an msPAF using the dose-addition principle. For this map, toxicity tests have been used that seek to quantify the no-observed-effect concentration (NOEC). The use of this endpoint links the result to the regulatory concept of “sufficient protection” of aquatic ecosystems. The above has been applied to the simulated concentrations of 1,785 chemicals on 365 consecutive days, and the 95 percentile of the results per site have been mapped.
The share of Trichoptera taxa sensitive to climate change in the European ecoregions
Trichoptera taxa are species with restricted distribution ('endemic species'), species inhabiting the crenal zone (springs), that cannot move further upstream, and species adapted to low water temperatures (cold stenothermy) in European ecoregions
Total pollutant emissions to water and transfers to UWWTPs by industry for EEA-33 in 2007 to 2017 by pollutant group
Total pollutant emissions to water and transfers to UWWTPs by industry from 2007 to 2017 by pollutant group
Water exploitation index (WEI) (total water abstraction per year as percentage of long-term freshwater resources in 1990 and 2002/2004)
The diagram illustrate per country WEI in 1990 and 2002/04
BOD5 concentrations in rivers between 1992 and 2010 draining to 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 included per sea region is given in parentheses. There were no stations with consistent data series on BOD7 in rivers draining to the Arctic Ocean. BOD7 data has been recalculated into BOD5 data.
Nitrate and phosphorus concentrations in selected WCE freshwater bodies
Numbers of groundwater bodies, lake and river monitoring stations in brackets
Northward shift and changes in occurrence of selected freshwater species
This indicator shows the evolution of the number of observations of Southern European dragonfly species in Flanders. Due to climate change the number of records of Southern European dragonflies increases in Flanders. Some species that were only occasional visitors in the past, such as Lestes barbarus now have permanent populations.
Number of introduced non-native freshwater species of various taxa which have an ecological effect
Number of species in the pan-European region listed as "worst invasive alien species threatening biodiversity in Europe" occurring in terrestrial and freshwater ecosystems
Nutrients in water bodies in the EU-27
Percentage of assessed freshwater animal species in each conservation class in the EU-25 per biogeographic region
The number of assessed species present in each region is given in brackets.
Inland bathing water quality in the European Union, 1990-2011
The figure shows the bathing water quality in different European countries over time: 1990, 7 EU Member States; 1991 to 1994, 12 EU Member States; 1995-96, 14 EU Member States; 1997 to 2003, 15 EU Member States; 2004, 21 EU Member States; 2005-06, 25 EU Member States; 2007 to 2011, 27 EU Member States. No inland bathing waters are reported from three Member States (Cyprus, Malta and Romania). The quality classes under the New Bathing Water Directive (2006/7/EC) are jointed with compliance categories under the Bathing Water Directive (76/160/EEC).
