TEHRAN — About 83 percent of air pollution in Tehran and 70 percent in other major cities in the country is caused by mobile sources, said Abdollah Motevalli, deputy director of the Standards and Quality Inspection Company.
There are two main types of air pollution sources, mobile sources such as cars, buses, planes, trucks and trains and stationary sources such as oil refineries, industrial plants and factories.
About 40 percent of emissions come from stationary sources, while 60 percent of pollution comes from mobile sources.
Mobile sources of pollution include cars, airplanes, and trains, while stationary sources include refineries, industrial units, and factories.Compliance with the implementing regulations and the issuance of the vehicle inspection certificate, the traffic police dealing with cars without inspection badges, and the intensification of inspection supervision will definitely reduce the impact of mobile sources on urban air pollution, Motevalli said.
He went on to say that in line with the implementation of the Clean Air Law, a total of 669 light vehicle technical inspection centers, 179 heavy vehicle centers and 447 hydrostatic laboratories were active nationwide, IRNA reported Sunday.
All motor vehicles, including light, semi-heavy and heavy-duty motorcycles, used by government, public and non-government sectors; are obliged to obtain a technical inspection certificate, which can be very effective in reducing air pollution, optimizing fuel consumption and vehicle safety, and therefore the health of citizens.
21,000 Iranians die from air pollution in a year
In the past [Iranian calendar] This year (March 2021-March 2022), air pollution has killed more than 21,000 people in 27 cities across the country, said Darioush Gol Alizadeh, head of the National Weather and Climate Change Center affiliated with the Environment Ministry, in August.
According to the Health Ministry report, about 21,000 deaths from PM 2.5 have occurred in 27 polluted cities in the country, causing $11 billion in damage, and 6,000 air pollution-related deaths have also been reported in Tehran.
above that [Iranian calendar] Year 1399 (March 2020-March 2021) 40 polluted days were reported in Tehran. Last year we also had 30 days of pollution and this year we have been breathing polluted air for 85 days since the beginning of the year, he explained.
Part of the emissions in Tehran are due to the traffic of diesel cars using regular diesel fuel, Gol Alizadeh said.
Around 34 million liters of petrol with the Euro 4 and Euro 5 standard are distributed daily in metropolitan areas and traffic junctions. According to the plan, by 2017 this should be 70 million liters, while the average daily consumption of petrol and diesel is 90 million liters. which reaches 105 million liters on some days, he lamented.
In winter, gas consumption in the household sector ranges from 550 million cubic meters to 650 million cubic meters, which has increased by 20 percent, and if we lower the temperature by one degree, there can be about 25 million cubic meters saved, and it can easily part of the need from power plants, he said.
