Main reason for air pollution in Tehran revealed

Iran has imported gasoline which contains Pollutant MMT (Methylcyclopentadienyl Manganese Tricarbonyl) – a gasoline additive that enhances octane to reduce knock.

The Iranian car manufacturers union has recently conducted a test on gasoline which is sold in Tehran.

It announced that the gasoline which contains MMT is the main reason for air pollution in the city, Iran’s Tasnim news agency reported on November 18.

The State Inspectorate Organization has corroborated that imported gasoline contains pollutant elements.

However, Shahrokh Khosravani, Deputy Head of National Iranian Oil Refining and Distribution Company (NIORDC) said that one of the ten gasoline consignments which were imported in July may contain pollutant elements.

Air pollution is measured in particle matter of 2.5 microns in diameter or PM 2.5, were clean air is between 0-50, safe air is 50-100, 100-150 is considered not safe, 150-200 is warning while over 200 is emergency level.

Last year, according to PSI (Pollutant Standards Index), Iran had 147 days during which air quality was substandard. Two years ago, this number stood at 217 days.

Iranian deputy oil minister, Abbas Kazemi, said on June 27 that the administration has taken the decision to import gasoline with the highest international standards.

Saeed Motesaddi, the deputy director of the Iranian Environment Protection Organization, said on October 17 that the administration has taken great steps toward the protection of natural environment.

“One of the most important steps was to stop the production of gasoline by petrochemical units,” Iran’s Shana news agency reported.

Iran’s oil minister Bijan Namdar Zanganeh said on May 23 that the “petrochemical gasoline’s quality is bad and inappropriate.”

In recent years, three petrochemical complexes were producing gasoline to meet the domestic need under the international sanctions imposed on the country’s oil sector, the Mehr news agency quoted managing director of the National Iranian Oil Refining and Distribution Company Abbas Kazemi as saying on May 17.
