Authorities have called for a full evacuation of a small town in central Bulgaria after a chemical tanker crashed, covering Debelets with a cloud of toxic fumes, AP reported. Police said the tanker - carrying an estimated 20 tons of styrene - crashed early Monday near the town of 4,500. Some 4 tons of the volatile chemical leaked from the vehicle, resulting in a toxic cloud. No injuries were reported and the leak was under control, police said. Styrene is a synthetic chemical used in the manufacture of rubber, plastic and fiberglass. Its fumes are believed to cause cancer when inhaled.
