The last two tests run on Danube water confirm a low level of alkalinity, despite the toxic mud. Yesterday, several dead fish were found after the toxic mud spilled out of an aluminium factory in Hungary had reached the second-longest river in Europe.& 13; The Government had specified that the flow of toxic wastes that flooded 40 square kilometers in the South-Western region of the Country, had reached the Raba River, a tributary of the Danube, but not yet the longest river in Europe. However, according to the report of the Chief of the Country’s Emergency Service, the red mud has nonetheless already completely destroyed the ecosystem of the Hungarian river Marcali.
