Azerbaijan, Baku, Oct.8/ Trend, F. Karimov/

Asphalt and mineral production units in Iran's capital,Tehran, have been temporarily closed due to air pollution in the city, ISNA quoted Tehran province's environment department director Mohammad-Hadi Heidarzadeh as saying.

Air pollution indicators show that the density of pollutant particles of less than 2.5 micron is 140 PSI and the density of pollutant particles of less than 10 micron is 120 PSI. So, the city is experiencing an unhealthy air, he added.

In July, Shargh newspaper quoted the head of Iranian Parliament's Environment Committee Mohammadreza Tabesh as saying that Tehran experienced 147 days in which air quality was substandard based on the PSI (Pollutant Standards Index) during the last solar year, which ended on March 21.

Tehran had 217 unhealthy days two years ago, he said.

The air over Iran's capital is among the most polluted in the world. Experts say many Iranians suffer serious health problems as a result.

Motor vehicles account for 70 percent of pollution in the Iranian capital. Low quality gasoline and diesel is partially responsible for the problem.

Officials say all car makers should be obliged to manufacture vehicles meeting Euro-4 and Euro-5 standards.

Iran currently produces 14 million litres of Euro-4 and Euro-5 gasoline per day. The amount will reach 22 million once the RFCC unit of Shazand oil refinery comes on stream.
