File chemical/x-pdb 50 years of protecting Europe's environment
Today the European Union has the most environmentally friendly arsenal of rules in the world and has done more to tackle pressing ecological problems, such as climate change, than any other major power. But it has not always been like this. Caring for the environment did not feature in the Treaty of Rome, the document that gave birth to the modern day EU. Yet environmental problems were never far away. Europe’s love affair with the car was moving into top gear, industry was busy belching out pollutants and raw sewage was being pumped into our rivers and seas.

GIS Map Application Ammonium in rivers
The map shows the mean annual concentration of total ammonium (TA), expressed as milligrams of N-NH4 per litre of water, observed in river monitoring stations and reported by EEA member countries via WISE. For most countries the mean annual value is based on observations over the whole year, whereas some countries only collect samples during the growing season (due to ice cover in winter). Total ammonium concentration can increase as a result of discharges from waste water treatment plants, industrial effluents and agricultural runoff. Ammonium exerts a demand on oxygen in water as it is transformed to oxidised forms of nitrogen. It is also an important nitrogenous fertilizer for aquatic plants, so it can cause eutrophication and indirectly reduce the dissolved oxygen due to increased BOD. In addition it is toxic to aquatic life at certain concentrations in relation to water temperature, salinity and pH. For example ammonium hydroxide in water is extremely toxic to fish and aquatic life at elevated pH levels. It can also pollute drinking water and bathing water. The purpose of the map is to provide an overview of the mean annual value of total ammonium in rivers across Europe and to enable the user to compare values per country or individual monitoring station, depending on the scale of visualisation. Historical data since 1993 can be displayed using the time slider.

Figure Annual average river nitrate concentration (mg/l NO3-N) in 2008, averaged by river basin district
This map shows the mean annual concentrations of Nitrate (NO3) as mg/L NO3-N measured at Eionet-Water River monitoring stations during 2008. 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)
