Pollution of the Danube River

IDENTIFICATION: European river originating in Germany and generally flowing eastward to the Black Sea

The Danube River, which passes through nine European countries, has suffered severe pollution from both natural and human sources. Maintenance of the river has been difficult because so many nations share its waters, but with the signing of the Danube River Protection Convention in 1994, improvements began to be made.

The source of the Danube is close to that of the Rhine, which flows north, making the pair of rivers a major waterway cutting through Central Europe. The Danube passes through or borders nine countries: Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, and Ukraine. Because the river’s tributaries affect other areas as well, the International Commission for the Protection of the Danube River (ICPDR) includes representatives from the Czech Republic, Slovenia, Bosnia and Herzegovina, Montenegro, and Moldova, as well as the European Union. In addition, the Danube basin includes Poland, Italy, Albania, and Macedonia, but these nations do not take part in the ICPDR.

The ICPDR was formed to carry out the mandates of the Danube River Protection Convention of 1994: to conserve and improve both surface water and groundwater of the Danube in a rational manner and to oversee the use of the river’s waters. According to the convention, the ICPDR constitutes the overall legal instrument for cooperation on transboundary water management in the Danube River basin. Its missions are to ensure the management of the waters of the and the distribution of those waters in an equitable manner, to prevent hazards from ice and flooding, and to prevent dangerous materials and from entering the Black Sea through the river. The parties to the convention have agreed to take all legal, administrative, and technical measures to maintain—or improve, if possible—the state of the water quality in the Danube and its basin and prevent any damage to the waters. The ICPDR also publishes the magazine Danube Watch, which is intended to inform the public about environmental issues concerning the Danube.

The members of the ICPDR and the members of the International Sava River Basin Commission (the Sava is a tributary of the Danube in southern Europe) issued a joint statement in October 2007, addressing the topics of navigation on the river and the river basin’s ecology. The statement noted both the positive and the negative effects that river navigation can have on the as shipping on the Danube replaces road transport. The commission members’ observations fit into a general transportation statement by the European Union covering the ecological impacts of all modes of transportation: road, rail, air, and river.

In 2008 the results of a scientific survey conducted by the ICPDR showed that the river had undergone remarkable improvement since the first such survey was taken in 2001. While the results were positive, the commission’s report on the survey findings emphasized that work still needed to be done. Swimming was possible in some areas of the river but not all. Fish taken from some parts were edible, but further investigation of mercury concentrations were still needed. Although significant populations of plants and animals still existed in the river, and the countries along the river had repaired many damaged areas, pollution of the river by plants in such major cities as Belgrade, Budapest, and Bucharest still needed attention.

By 2016, the major threats to the health of the river and its surroundings reportedly came from microplastics (particles of plastic waste), pharmaceuticals, and agricultural runoff. Insufficient data regarding the types of potential pollutants in the Danube hampered pollution mitigation efforts. The ICPDR continued its work in 2024, publishing annual reports, management plans, and an official magazine, Danube Watch. The organization remained committed to researching issues affecting the Danube River, including agriculture, drought, flood, invasive species, ecosystems, and water quality.
