Organic contamination in central Europe.
Toxic spill in Hungary. From the reservoir in the aluminum plants in Ajka (Hungary) leaked around 600-700 thousand cubic meters of toxic substance, containing liquor and non-ferrous metals. Around drowned in brown slime.
Aluminum is typically extracted from bauxite ore using sodium hydroxide. For every one ton of aluminium extracted approximately two tons of highly alkaline red sludge is produced, the color of which comes from iron oxide,
Normally, the sludge contains heavy metals and whatever else is found in the rock besides aluminium, which can include copper, zinc, arsenic and sometimes radioactive elements
The Hungarian government has declared a state of emergency as toxic mud travels rapidly in tributaries towards the Danube River, facilitated by heavy rains and flooding.
