The toxic red sludge that caused a catastrophe in the west Hungarian countryside in an unprecedented spill will sooner or later reach the Bulgarian sector of the Danube, according to eco-activists.
"What is worrisome is that no-one is really sure what exactly is contained in the sludge or when it will reach Bulgaria," stated Ivan Hristov from WWF Bulgaria.
He said that in view of that a constant monitoring of the contents of Danube waters is necessary.
The WWF representative also drew attention to similar industrial repositories in Bulgaria and their safety, saying more than 20 of them currently exist in the country.
The red sludge has already polluted Hungarian rivers Torna, Marcal and Raba, which eventually flow into the Danube.
Bulgarian authorities have reported no pollution of the Bulgarian Danube stretch this far.
Some 1 M cubic meters of the toxic substance are estimated to have leaked from the facilities, causing the deaths of 9 persons, injuring dozens and ruining the property of hundreds.
