A holiday is supposed to be a fun off day to enjoy life in some fashion. For the second time in a month, heavy air pollution in Iran’s smog-filled capital has forced authorities to close government offices and schools and declare a two-day public holiday because of the health dangers of being outdoors. Yet this happened in July 2009 too when Iranian authorities declared public holiday in the capital Tehran after a sandstorm blotted out the already heavily polluted city. All of this is caused by several factors, some man made and some due to local climate and geological conditions. It is also not unique for Tehran though that city is suffering in the extreme.
