Romania is being hit with acid rain and increased water and air pollution as a direct result of NATO’s bombing campaign in Yugoslavia, the Romanian environment ministry said yesterday. Air pollution from fires following the bombings has caused acid rains in areas of Romania along the Yugoslav border. The ministry said that environmental damage has not been serious so far, but there could be long-term effects on the Danube River and Black Sea. Meanwhile, Serbia’s leading opposition party warned yesterday that Serbia is facing an ecological catastrophe because of NATO’s air strikes, claiming bombs have hit several chemical sites across Serbia, spilling toxics into the air and water.
