Right next to Hortobagy National Park – the oldest and possibly most sensitive national park of Hungary - lies an abandoned toxic waste repository. Three to four thousand tonnes of dangerous chemicals (including trichloroethylene compounds and other chlorinated solvents, galvanic sludge and cyanide-based tempering salts) are flowing out freely from the mouldering barrels of the repository into the ground. The warehouse has no walls and its top is almost completely in ruins.
