Tehran Closed Schools Due to Air Pollution
Every year with the drop in temperature in winter, a phenomenon known as temperature inversion occurs during which cold air underpins warm air at higher altitude, leading to the entrapment of air pollutants in the city, which causes heavy smog. The parliament has only belatedly started reviewing the 35-article Clean Air Bill, after letting it gather dust for nearly two years. Unfortunately, progress remains slow. The bill singles out inefficient vehicles, substandard fuels, industrial activities and dust storms as the major sources of air pollution in the country.
Drawn up by DOE in cooperation with other bodies, the bill proposes more frequent technical inspections of private vehicles. While the current law stipulates technical inspection of all vehicles once every five years, DOE is pushing for biennial checks. The department insists that government vehicles should also be subjected to annual inspections. The government has banned the production of highly-polluting, carburetor-equipped motorcycles from September and is urging people to opt for eco-friendly electric ones. The administration has been distributing Euro-4 gasoline in major cities for months and has ordered automakers to make their products comply with the standard. Experts say the three main sources of air pollution in Iran are motorcycle carburetors (a device that blends air and fuel in the engine), diesel cars without filters and gasoline gas guzzlers. They say if 10% of the highly-polluting clunkers are removed from the streets, it will help reduce vehicular pollution by 48%.
