Figure Biochemical Oxygen Demand (BOD5) and total ammonium concentrations in rivers between 1992 and 2010
Concentrations are expressed as annual mean concentrations. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations included per country is given in metadata (see downloads and more info). BOD7 data has been recalculated into BOD5 data.

Indicator Assessment Oxygen consuming substances in rivers (CSI 019) - Assessment published Oct 2012
Concentrations of BOD and total ammonium have decreased in European rivers in the period 1992 to 2010 (Fig. 1), mainly due to general improvement in wastewater treatment. See also WISE interactive maps: Mean annual BOD in rivers and Mean annual Total Ammonium in rivers

GIS Map Application WISE SoE BOD in rivers
This map shows the mean annual concentrations of BOD (Biochemical oxygen demand) measured at Eionet-Water River monitoring stations from 1992 till 2011. All data are annual means. The purpose of the map is to provide an overview of the annual concentrations of BOD 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. BOD (Biological - or biochemical - Oxygen Demand) refers to the amount of organic matter present in water that will consume oxygen as it is decomposed by micro-organisms. BOD is commonly used for 5-day BOD (BOD5); for those Member States reporting 7-day BOD (BOD7), these values have been converted to BOD5 (BOD7 = 1.16 BOD5) for reasons of comparability.Large quantities of organic matter (microbes and decaying organic waste) in water are a potential risk to aquatic ecosystems and human health. A reduction in the amount of oxygen in water as a result of the decomposition of organic matter can endanger aquatic life through asphyxiation and disrupt the ecological balance of the water. It can also pollute water used for drinking and bathing. High levels of BOD can indicate such pollution. In less detailed scale, data is aggregated by country and pie charts are displayed. In more detailed scale individual stations appear in shape of triangles. Historical data (from 1992 on) can be displayed and viewed with time slider tool.

Figure Total ammonium concentrations in rivers 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). The number of river monitoring stations included per geographical region is given in parentheses.

Figure Nitrate concentrations in rivers 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). The number of river monitoring stations included per geographical region is given in parentheses

Data Waterbase - Rivers
Waterbase is the generic name given to the EEA's databases on the status and quality of Europe's rivers, lakes, groundwater bodies and transitional, coastal and marine waters, and on the quantity of Europe's water resources

Figure Chemical status of rivers and lakes
The graphs illustrate the chemical status of river and lake water bodies as percentage of water bodies in poor and good chemical status, by count of water bodies.

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.
