Tehran, Iran, Jan. 25
By Mehdi Sepahvand - Trend:
Researchers at Sharif University of Technology have published a report, which says that every year 725,000 tons of pollutants are emitted into the air in Iranian capital of Tehran.
Dr. Hossein Afshin used the help of a crew of some ten students to collect data on air pollution in Tehran during the last Iranian year, which ended March 20, categorizing sources of pollution alongside the volume of particles that enter the air, ISNA news agency reported Jan. 25.
The report shows that 85 percent of the pollutants come from mobile sources and the rest from static ones.
It further details that diesel vehicles and motorcycles are the major producers of particulate matters in the air in the capital city.
While in developed countries such reports are issued annually, the latest such report in Iran prior to Afshin's came 11 years ago. The reports are crucial to environmental and municipal decision-makings to tackle air pollution.
Due to severe air pollution in Tehran, the government closes schools and reduces working hours on many occasions throughout the year to reduce health issues it causes to people, especially to the youth.
