The death toll from a toxic sludge spill at an alumina plant in Hungary rose to nine after an elderly man died overnight, the National Disaster Management Directorate said on Wednesday, according to RIA Novosti. At least 50 people are still in hospital. Some 700,000 cubic meters of caustic by-product burst from a storage reservoir in Ajka, some 160 km west of Budapest, on October 4. Emergency services are building a barrier near the neighboring village of Kolontar to protect the area after the broken reservoir spewed out a second wave of sludge. CNN reported yesterday that the aluminum plant that caused the spill will resume production at the end of the week.
