The Second Regional Stakeholders Meeting
Transboundary Air Pollution Plan of Islamic Republic of Iran
Presented by
Vahid Esfahanian
Vehicle, Fuel and Environment Research Institute

2. Outline Introduction Monitoring Plan Plan for Emission Inventory
Plan for air pollution Modeling
Preliminary design of an air quality network for Tehran

3. Introduction
The prediction and management of air quality is gaining increasing importance around the world.
The present situation in Asia is that air pollution problems associated with long rang transport of pollutants
The issue of spatial scale for air pollution management has become more important as scientists and policy makers realize that current management programs operating within human-designated jurisdictions may not be large enough.

4. Monitoring Plan
Existing station
New stations

5. Monitoring Plan …. Existing station Name: Chamsari Area: one Hectar
Location: 40 km at the south of Ilam, near the common border of Iran-Iraq
Geographical location:

6. Monitoring Plan …. Existing station …. The recording pollutants are:
NO2
SO2
PM10

7. Monitoring Plan …. Existing station ….
Another air pollutants of interest from the stand point of long range transport are:
Ozone (O3)
Volatile Organic Compounds (VOC)
At the second step if there is enough fund toxic air pollutants should be recorded in Chamsari station.
Heavy metals like mercury and lead
Manmade chemicals like polychlorinated biphenyls (PCB)
Polycyclic organic matter (POM)
Pesticides like dichlorodiphenyl-trichloroethane (DDT)

8. Monitoring Plan …. New stations
Vast surface area of Iran ( km2)
Pollutants transported over Iran from Europe and west Asia toward south Asia
Due to geographical situation of Iran and propinquity to neighboring countries including Iraq and central Asia states, where the concentration of pollutants is high
Iran needs some new stations to well monitor the inflow and outflow of air pollutants.

9. Monitoring Plan …. New stations ….
Another important issue in transboundary air pollution is meteorological parameter
Wind speed
Wind direction
The north, north-west and west of Iran are the locations where the air pollutants flow toward Iran
The north east of Iran is the location where air pollutant flow out of Iran
In other boundaries including south and south-east boundaries the intensity of flow is not much strong

10. Monitoring Plan …. New stations ….
The more stations should be established in boundaries where the intensity of inflow and outflow is high.

11. Plan for Emission Inventory
Three main categories of air pollution sources are:
Mobile Sources
Point Sources
Area Sources

12. Plan for Emission Inventory …
Mobile Sources
Point Sources
Road Traffic
Rail Traffic
River Traffic
Aircraft
Large Industrial Processes
Small Industrial Processes
Large Boiler Plant
Area Sources
Gas Combustion (domestic and commercial)
Oil Fuel Combustion (domestic and commercial)
Coal Combustion (domestic and commercial)
Agriculture and Nature
Other

13. Plan for Emission Inventory …
Iran should establish some station all over Iran and
Implement some project
To obtain reliable statistics of emission inventory

14. Plan for air pollution Modeling
An air quality model can predict the concentrations of pollutants
Air quality models can determine the origins of pollutants
Models can be used to predict the future concentration of a particular pollutant after the implementation of a new pollution control program
In general all of models require two types of data:
Information about the source being modeled, including the pollutant emission rate
Information about the dispersing characteristics of the meteorology surrounding the source, such as wind speed and direction.

15. Plan for air pollution Modeling …
DOE of Iran joint with Vehicle, Fuel and Environmental Research Institute (VFERI) of university of Tehran are implementing the air pollution models over Iran.
and
hopefully in future for other regions
