Toxic gases have been in the air for two weeks in and around the Crimean city of Armyansk. All the children have now been evacuated from the area.
The occupying government have explained that acid from the local chemical plant Crimean Titan has dried and now actively emits sulfur trioxide into the air. This toxic gas is very dangerous, it causes rashes and affects respiratory organs. When sulfur trioxide and water (including water in the air) come into contact, sulfurous acid is produced.
