Kolontár, 4 October 2010. A dam at a Hungarian aluminium factory near Kolontár broke. Approximately 1.5 million cubic metres of alkaline red sludge and water were released with disastrous consequences: 10 people died, hundreds of hectares of agricultural land were contaminated. One year after these events, we collected information on the current environmental conditions in the area. As an ongoing effort, the Accident Prevention and Control Expert Group of the ICPDR continues its work to avoid or mitigate such disasters in the future.

Ajka, 15 November 2011. The redsludge accident of October 4 has generated a world-wide interest in the area of Ajka in Western Hungary. Since then, media attention has ceased. This article aims to provide an English summary of the measures that were taken to manage the accident since October 20.

Kolotar, 4 October 2010. The acute toxic risk deriving from the heavy metals in the red sludge is rather low, as their concentrations are rather low. However, the chronic toxicity threat is high.

The Accident Emergency Warning System (AEWS) of the Danube River Basin is activated whenever there is a risk of transboundary water pollution, or threshold danger levels of certain hazardous substances are exceeded.

Accidental pollution in the Danube River Basin can cause widespread damage to the environment, and endanger the health of local people and the state of local economies downstream. This was exemplified by the effects of the Baia Mare cyanide spill in Romania in 2000 or by the Hungarian redsludge accident at Ajka in 2010. The ICPDR is working to prevent accidental pollution and to improve response capability by compiling an inventory of all relevant "Accident Risk Spots".

Hazardous substances can remain in the environment for a very long time, and harm ecosystems and human health. Although monitoring indicates that the loads of some substances have been reduced in recent years, many problems still persist. The increasing number of these man-made substances present in the environment is a matter of concern, and calls for the application of the precautionary principle.
