    The air pollution in downtown Cairo is more than 10 to 100 times of acceptable world standards. [8] Cairo has a poor factor because of lack of rain and its layout of tall buildings and narrow streets, which create a bowl effect (bad ventilation and consequent trapping of pollutants). The main air pollution problem in Egypt is particulate matter.
