Tehran, Oct 18, IRNA – A deputy at the Department of Environment (DoE) said the ratio of clean air in the first six months of the current calendar year has been tripled as compared to the same period last year.


 
Saeed Motesadi told IRNA on Saturday that statistics show that unpolluted days of the current year increased by 10% and polluted days reduced by 25% in comparison with the last year.


Meanwhile, he added, a comparison between clean days of the current year (1393) and the year 1390 (March 2011 – March 2012) shows that clean days have a six-fold increase and unpolluted days reduced by 50%.

Pointing to the statistics, Motasadi said since the beginning of the current year (March 21) up to October 12, altogether 6 days the air was clean, 146 days was unpolluted and 53 days was polluted whereas the corresponding figures for the last year were 2, 132 and 71 days respectively. The figures for 1391 show no clean days, 135 unpolluted days and 70 polluted days and for a year before it, 1390, no clean day, 72 unpolluted days and 133 polluted days.

This year, he further remarked, most polluted days were after the storm on June 2 as polluted days were mostly dusty.

The official said that distribution of standardized fuel, elimination of petrochemical gasoline and standardization of vehicles were among measures that reduced air pollution in the big cities, including Tehran.
