Schools Closed in Tehran Due to High Pollution Level

Schools in the Iranian capital were closed and the elderly, the sick and children advised to stay indoors yesterday after air pollution reached alarming levels.

According to Tehran’s official Air Quality Control Unit, Saturday’s Pollutant Standard Index (PSI) — a standard measurement that incorporates carbon monoxide, dust and other pollutants — reached168 , or close to “very unhealthy.”

"There was a lack of any parameter in the atmosphere to decrease the pollution,” a Tehran pollution official, Elmira Parto, told AFP in reference to the current season marked by low winds.

Following the order to close elementary and junior high schools for the day in a bid to reduce traffic, the PSI for Tehran was reported to have fallen to 113 - closer to Saturday’s level in other cities such as Beijing and Shanghai.

By comparison, Saturday’s PSI in New York was 52 and in Bangkok57 . The soaring pollution in Terhan - often blanketed in a veil of thick brown smog — has been attributed to a rapid increase in traffic and congestion.

Half of the four million vehicles in the city of 10 million are more than 20 years old and, according to official figures, the average petrol consumption is 17 liters per100 kilometers, more than three times as much as for European cars.

IRIB state television called on elderly people, especially those with cardiac problems, to stay home. Many residents in downtown Tehran wore masks to protect themselves from severe pollution which even blocked the view of the Elburz Mountains in the north.

IRIB announced a relaxation of the measures at noon yesterday as pollution levels had dropped after people followed municipal recommendations to use only public transportation means.

According to a recent study, each resident of the Iranian capital — now considered one of the world’s most polluted cities, inhales an estimated7 . 1to9 . 3kilograms of dust every year.

The poor air quality has been blamed for an increase in respiratory ailments, and asthma is increasingly common.
