Planes To Drop Water Over Tehran In Desperate Attempt To Cut Smog

[hatrack]

Noting that Tehran's air pollution is still at an alarming level due to the accumulation of pollutants and the pattern of air inversion, IEPO Managing Director Mohammad Javad Mohammadizadeh said on Sunday that 10 airplanes will sprinkle water over the Iranian capital. He told Fars news agency that the project will start on Monday or Tuesday with the cooperation of Agricultural Jihad Ministry and will last for two days.

The Iranian official added that the organization's researchers are trying to find ways to shake up the atmosphere to produce rain or create artificial wind corridors to blow the thick haze away. Moreover, Tehran Governor General Morteza Tamaddon said that the IEPO is designing ventilation and air conditioner systems to be installed in about a hundred polluted spots of the choking capital.

Earlier on Saturday, Tehran's deputy governor general for development affairs, Mohammad Reza Mahmoudi, said that air pollution in some parts of the city has reached a critical level. Pollution was at its worst in Shahr-e Rey, Azadi, Razi and Qiyam areas in the southern districts and Tehran in general was on "alert level" with a Pollution Standards Index (PSI) of 151.

PSI is a yardstick for determining the concentration of various pollutants in the air, such as carbon monoxide, sulfur dioxide, nitrogen compounds, ozone and suspended floating particles. A PSI of more than 100 hints at polluted or unhealthy conditions.
